THEORY-CONCEPT

Web Application:

A web application runs over the Internet. Ex. eBay,Amazon ,Google, facebooketc

A webapp contains five components:

1.HTTP Server: Examples are- Google Web Server , Apache HTTP Server, Apache

Tomcat Server, Microsoft Internet Information Server (IIS) etc

2.HTTP Client (Web Browser): Examples are- Internet Explorer, Firefox, Google Chrome,

Safari etc.

3.Database:Examples are- MySQL, Apache Derby, MS SQL Server, SQLite, PostgreSQL,

Commercial Oracle, IBM DB2, SAP SyBase, MS Access etc

AISSMS COE, PUNE Page 1

4.Client-Side Programs: It can be written in HTML Form,VBScript, JavaScript, Flash etc.

5.Server-Side Programs: could be written in Java Servlet/JSP, ASP, PHP, Perl, Python,

CGI, and others.

A web app is 3-tier (or multi-tier) client-server database application which run over the

Internet as shown in the following diagram,

Figure.1: Three-Tier Client-Server Architecture

1. To start a webapp, A user, issues a URL request via a web browser (HTTP client), to

HTTP server.

2. The HTTP server returns an HTML form (client-side program), which is loaded into the

client's browser.

3. The user fills up the query data inside the form and submits that form.

4. The client-side program sends the query parameters to a server-side program.

5. The server-side program receives the query parameters, queries the database based on

these parameters, and returns the query result to the client-side program.

6. The client-side program displays the query result on the browser.

Apache tomcat

Tomcat is an open-source project, under the "Apache Software Foundation" (which also provides

the most use, open-source, industrial-strength Apache HTTP Server). The mother site for Tomcat

is http://tomcat.apache.org. Alternatively, you can find tomcat via the Apache mother

site:http://www.apache.org.

EXECUTION STEPS

1. Goto http://tomcat.apache.org

2. Select tomcat version 8 from left side list under Download option (tomcat 8) or select a

link 32-bit/64-bit Windows Service Installer (pgp, md5, sha1, sha512)

3. Download and run ‘.exe ‘ file.

4. I preferred, installation of Tomcat at C:\Program Files (x86)\Apache Software

Foundation

5. Use the default settings and provide a password that you will remember.

6. Now you will find the Tomcat installed at C:\Program Files (x86)\Apache Software

Foundation\Tomcat 8.0

How to Run Tomcat

Following are the steps to check whether Tomcat has been installed successfully or not-

1. Find start program in the Programs Menu. Look under Apache Tomcat and select "Start

Tomcat" or “startup.bat”.

2. Open any web browser and type in the given URL:

o http://localhost:8080/

Now, you will see the Tomcat home page, which is provided by the Tomcat Web server running

on your computer. To shut down your server and remove the Console window, select "Stop

Tomcat" in the same menu of where you selected "Stop Tomcat".

Tomcat's Directories

It contains the following sub-directories:

• bin: It contains the binaries; startup script (startup.bat for Windows and startup.sh for

Unix and Mac OS), shutdown script (shutdown.bat for Windows and shutdown.sh for

Unix and Mac OS), as well as other binaries and scripts.

• conf: It contains the system-wide configuration files such

as server.xml, web.xml, context.xml, and tomcat-users.xml.

• lib: It contains the Tomcat's system-wide JAR files, which can be accessible by all

webapps. We can also place external JAR file (such as MySQL JDBC Driver).



• logs: It contains log files of Tomcat. Also, you can check error messages here.



• webapps: It contains the webapps to be deployed. You can also place the WAR (Webapp

Archive) file for deployment here.



• work: Tomcat's working directory used by JSP, for JSP-to-Servlet conversion.



• temp: Temporary files are stored in this directory.

How to set a path for Windows

Assuming you have installed Java in C:\Program Files (x86)\Java\jdk 1.7.0directory −

• Right-click on 'My Computer' and select 'Properties'.



• Click the 'Environment variables' button under the 'Advanced' tab.

Now, alter the 'Path' variable so that it also contains the path to the Java executable. Example,

path set to C:\Program Files (x86) \Java\jdk1.7.0\bin

through command prompt you can set the path by following command

set path=C:\Program Files (x86) \\Java\jdk1.7.0\bin

2. Apply CSS to HTML pages.

SOFTWARE & HARDWARE REQUIREMENTS

Software: Notepad, Browser

THEORY-CONCEPT

HTML: HTML is the standard markup language for creating Web pages.

• HTML stands for Hyper Text Markup Language



• HTML describes the structure of Web pages using markup

AISSMS COE, PUNE Page 6

Web Technology Lab Manual

• HTML elements are the building blocks of HTML pages



• HTML elements are represented by tags



• HTML tags label pieces of content such as "heading", "paragraph", "table", and so on



• Browsers do not display the HTML tags, but use them to render the content of the page



• HTML Versions:

HTML

1991

HTML 2.0

Table.1: HTML Versions

CSS:

CSS stands for Cascading Style Sheet. It is nothing, but design language intended to simplify

the process of making web pages presentable.CSS handles the feel and look part of a web

page.By using CSS, one can control the color of text, style of fonts, spacing between

paragraphs, layout designs.

CSS is easy to learn, easy to understandand it provides powerful control on presentation of an

HTML document.

Advantages of CSS:

It saves the time, Pages load faster, Easy maintenance, Superior styles to HTML, Multiple

Device Compatibility, Global web standards, Offline Browsing, Platform Independence.

CSS3 Modules:

CSS3 Modules are having old CSS specifications as well as extension features.

• Box Model



• Selectors



• Background



• Border



• Image Values and Replaced Content



• Text Effects

AISSMS COE, PUNE Page 7

Web Technology Lab Manual

• Animations



• 2D/3D Transformations



• Multiple Column Layout



• User Interface

TECHNOLOGY / TOOL

• The <!DOCTYPE html> declaration defines this document to be HTML5



• The <html> element is the root element of an HTML page



• The <head> element contains meta information about the document



• The <title> element specifies a title for the document



• The <body> element contains the visible page content



• The <h1> element defines a large heading



• The <p> element defines a paragraph



• HTML tags are element names surrounded by angle brackets:

<tagname>content goes here...</tagname>

CSS can be added to HTML elements in 3 ways:

• Inline - by using the style attribute in HTML elements. An inline CSS is used to apply a

unique style to a single HTML element.



Ex. <h1 style="color:blue;">This is a Blue Heading</h1>



• Internal - by using a <style> element in the <head> section. An internal CSS is used to

define a style for a single HTML page. An internal CSS is defined in the <head> section

of an HTML page, within a <style> element.



Example:<style>

body {background-color: powderblue;}

h1 {color: blue;}

p {color: red;}

</style>

AISSMS COE, PUNE Page 8

Web Technology Lab Manual

• External - by using an external CSS file. An external style sheet is used to define the style

for many HTML pages. With an external style sheet, you can change the look of an entire

web site, by changing one file!To use an external style sheet, add a link to it in the

<head> section of the HTML page.



Example: <link rel="stylesheet" href="styles.css">



• Use the HTML <head> element to store <style> and <link> elements



• Use the CSS color property for text colors



• Use the CSS font-family property for text fonts



• Use the CSS font-size property for text sizes



• Use the CSS border property for borders



• Use the CSS padding property for space inside the border



• Use the CSS margin property for space outside the border

DESIGN / EXECUTION STEPS

Following steps are used to Create and Execute web applications,

1. Write the HTML code in notepad and save with .html extension.

2. Write the CSS code in notepad and save with .css extension.

3. Import CSS file in HTML page.

4. Open HTML page in the browser.

TEST CASES

Title: XML and CSS

PROBLEM STATEMENT

Write a program to design book catalog by using XML and CSS to display tile, author, price and

year of the book.

OUTCOMES

Students will be able to,

1. Design static webpage using XML.

2. Apply CSS to XML pages.

SOFTWARE & HARDWARE REQUIREMENTS

Software: Notepad, Any Browser

THEORY-CONCEPT

XML stands for Extensible Markup Language. It is nothing but the text-based markup language

which is derived from Standard Generalized Markup Language(SGML).

XML tags identify the data and are used to store and organize the data, rather than specifying

how to display it like HTML tags, which are used to display the data. XML is not going to

replace HTML in the near future, but it introduces new possibilities by adopting many

successful features of HTML.

There are three important characteristics of XML that make it useful in a variety of systems and

solutions −

AISSMS COE, PUNE Page 14

Web Technology Lab Manual

• XML is extensible − XML allows you to create your own self-descriptive tags, or

language, that suits your application.



• XML carries the data, does not present it − XML allows you to store the data

irrespective of how it will be presented.

XML is a public standard − XML was developed by an organization called the World Wide

Web Consortium (W3C) and is available as an open standard.

TECHNOLOGY/TOOL

The XML document have an XML declaration, but it is optional, and it is written as−

<? xml version = "1.0" encoding = "UTF-8"?>

Where version is nothing but the version of an XML document and UTF specifies the character-

encoding used in the document.

Each XML-element needs to be closed either with start or with end elements as shown below −

An XML document can have only one root element.

<root>

</root>

XML Attributes:

Using a name/value pair, an attribute specifies a single property for an element. An XML-

element can have one or more attributes. For example −

<a href = "http://www.google.com/">XMLTutorial</a>

Here href is the attribute name and http://www.google.com/ is attribute value.

DESIGN/EXECUTION STEPS

Following steps are used to Create and Execute web applications,

1. Write the XML code in notepad and save with .xml extension.

2. Write the CSS code in notepad and save with .css extension.

AISSMS COE, PUNE Page 15

3. Import CSS file in XML page.

4. Open XML page in the browser.

TEST CASES

Manual testing is used to check whether CSS gets applied or not.

HTML, Java Script

OBJECTIVES

1. Understand about basic concepts of JavaScript.

2. Use JavaScript for validation of data.

PROBLEM STATEMENT

Write a program to design registration form for students by using HTML, CSS& Java Script and

perform following validations: all fields mandatory, phone number and email address validation.

OUTCOMES

Students will be able to,

1. Design static webpage using HTML.

2. Apply JavaScript to HTML pages for validation of data.

SOFTWARE & HARDWARE REQUIREMENTS

Software’s: Notepad, Any Browser

THEORY-CONCEPT

JavaScript is a programming language of HTML as well web. It is preferred for creating

network-centric applications.It is integrated and complimentary with Java. As JavaScript is

integrated with HTML it is very easy to implement. It is open as well as cross-platform.

Advantages:

AISSMS COE, PUNE Page 19

Web Technology Lab Manual

The advantages of using JavaScript are −

• It requires less server interaction



• Immediate feedback to the visitors



• Increased interactivity



• Richer interfaces

Validation:

When client enters the all necessary data and press the submit button form validation is

done at server side If data entered by a client is incorrect or missing,the server needs to send all

data back to the client and request for resubmission of form with correct information. This is

really a lengthy process which puts a lot of load(burden) on the server.

So, JavaScript provides a way to validate form's data on the client's side itself before sending it

to the web server. Form validation performs two functions-

• Basic Validation –First of all the form must be checked to make sure all the mandatory

fields are filled in. It would require just a loop through each field in the form and check

for the data.



• Data Format Validation − Secondly, the data that is entered must be checked for correct

format and its value. The code must include appropriate logic to test correctness of data.

TECHNOLOGY/TOOL

JavaScript can be implemented using JavaScript statements that are placed within the <script>.

You can place the <script> tags, containing your JavaScript, anywhere within your web page,

but it is normally recommended that you should keep it within the <head> tags.

The script tag takes two important attributes:

• Language − This attribute specifies what scripting language you are using.

Typically, its value will be JavaScript. Although recent versions of HTML (and

XHTML, its successor) have phased out the use of this attribute.



• Type − This attribute is what is now recommended to indicate the scripting language

in use and its value should be set to "text/javascript".

AISSMS COE, PUNE Page 20

Web Technology Lab Manual

DESIGN/EXECUTION STEPS

Following steps are used to Create and Execute web applications,

1. Write an HTML code in notepad and save with .html extension.

2. Write the function for validation of email id and phone no and enclosed this function in

script.

3. Call this function on ‘onClick’ event of submit button.

4. Open HTML page in the browser.

TEST CASES

Manual testing is used to check following validations

• All the fields like Full name, Class, Department, Address, Phone number and email id are

mandatory fields.



• Phone no. should be numbers only.

 Email id should be in proper format like abc@abc.com

CONCLUSION/ANALYSIS

Hence, we applied validate the data using JavaScript.

Web Technology Lab Manual

THEORY - CONCEPT

Java Server Pages (JSP): It is a server side programming technology that is used to create

dynamic web-based applications. JSP have right to use the complete Java APIs, including the

JDBC API to access the databases.

It is a technology that helps software developers to create dynamic web pages based on HTML,

XML and other document types. It was released in 1999 by Sun Microsystems. It is just like a

PHP and ASP, but it uses the Java programming language.

A JSP element is a type of java servlet that is designed to accomplish the role of a user interface

for a java web application. Web developers write JSPs as text files that combine HTML or

XHTML code, XML elements, and rooted JSP actions and commands.

Using JSP, you can collect input from users through webpage forms, current records from a

database or another source and create web pages dynamically.

JSP tags can be used for different purposes, such as retrieving information from a database or

registering user preferences, accessing JavaBeans components, passing control between pages,

and sharing information between requests, pages etc.

Why we need JSP?

JSP is used for the design of dynamic web page and servlet is used to code the logic that is

present i.e. in the MVC (Model-View-Controller) architecture, the servlet is the controller and

the JSP is the view.

Architecture of JSP

1. The request / response part of a JSP is defined in below architecture

2. The client initiated request for a JSP file using browser

3. Webs server (i.e, JSP Engine) invokes the JSP file and interpret the JSP file produce a

java code. The created java code will be a Servlet.

4. Once Servlet is created, JSP engine compiles the servlet. Compilation errors will be

5. Now servlet class is loaded by the container and executes it.

Figure.2: Architecture of JSP

Syntax of JSP:

JSP declarations is used to declare variables and methods as shown below,

<% text %>

Following is the simple and first example for JSP:

//Hello.jsp

<html>

<head>

</head>

<body>

out.println("Welcome to JSP Class");

</body>

</html>

Output:

Welcome to JSP Class

Servlet:

A Servlet is a server side program and written in Java. Servlet is a web component that is

deployed on the server for creating the dynamic web pages. A Java servlet is a Java program that

extends the capabilities of a server. Although servlets can respond to any types of requests, they

most commonly execute applications hosted on Web servers.

TECHNOLOGY/TOOL IN BRIEF

1. JSP and Servlets

2. IDE: NetBeans 7.0 or Later

3. Databases: MySQL

NetBeans: NetBeans is an IDE, used for quickly and easily developing java desktop, mobile,

and web applications, as well as HTML5 applications with HTML, JavaScript, and CSS. Also

provides a huge set of tools for PHP and C/C++ developers. It is free and open source tool and

has a great community of users and developers around the world.

MySQL: MySQL is a freely available open source Relational Database Management System

(RDBMS). It uses the Structured Query Language (SQL).

SQL is the most popular language for adding, accessing and managing data in a database. It is

most noted for its quick processing, proven reliability, ease and flexibility of use. MySQL is an

essential part of almost every open source PHP application. Good examples for PHP & MySQL-

based scripts are WordPress, Joomla, Magento and Drupal.

THEORY-CONCEPT

1. PHP:

The PHP Hypertext Preprocessor (PHP) began as a little open source venture that advanced as an

ever increasing number of individuals discovered how valuable it was. Rasmus Lerdorf released

the principal form of PHP route in 1994. PHP is a recursive acronym for "PHP: Hypertext

Preprocessor".

PHP is a server side scripting dialect that is installed in HTML. It is utilized to oversee dynamic

substance, databases, session following, even form whole internet business locales. It is

incorporated with various prevalent databases, including MySQL, PostgreSQL, Oracle, Sybase,

Informix, and Microsoft SQL Server.

PHP is pleasingly zippy in its execution, particularly when gathered as an Apache module on the

Unix side. The MySQL server, once began, executes even extremely complex questions with

colossal outcome sets in record-setting time.

PHP bolsters a substantial number of real conventions, for example, POP3, IMAP, and LDAP.

PHP4 included help for Java and conveyed question designs (COM and CORBA), making n-

level improvement a plausibility out of the blue. PHP is excusing: PHP dialect tries to be as

pardoning as would be prudent. PHP Syntax is C-Like.

PHP performs framework capacities, i.e. from documents on a framework it can make, open,

read, compose, and close them. PHP can deal with frames, i.e. accumulate information from

records, spare information to a document; through email you can send information, return

information to the client.

You include, erase, adjust components inside your database through PHP. Access treats factors

and set treats. Utilizing PHP, you can confine clients to get to a few pages of your site. It can

encode information.

AISSMS COE, PUNE Page 41

Web Technology Lab Manual

Example:

"Hello World" Script in PHP

To get a feel for PHP, first start with simple PHP scripts. Since "Hello, World!" is an essential

example, first we will create a friendly little "Hello, World!" script.

As mentioned earlier, PHP is embedded in HTML. That means that in amongst your normal

HTML (or XHTML if you're cutting-edge) you'll have PHP statements like this –

<html>

<head>

<title> Hello World</title>

</head>

<body>

<?php echo (“Hello Php”); ?>

</body>

</html>

To create and run PHP Web pages three fundamental parts should be introduced on your PC

framework.

Web Server − PHP will work with for all intents and purposes all Web Server programming,

including Microsoft's Internet Information Server (IIS) however then regularly utilized is

unreservedly accessible Apache Server. Download Apache for nothing here −

https://httpd.apache.org/download.cgi

Database − PHP will work with for all intents and purposes all database programming,

including Oracle and Sybase yet most regularly utilized is uninhibitedly accessible MySQL

database. Download MySQL for nothing here − https://www.mysql.com/downloads/

AISSMS COE, PUNE Page 42

Web Technology Lab Manual

PHP Parser − keeping in mind the end goal to process PHP content directions a parser must be

introduced to create HTML yield that can be sent to the Web Browser. This instructional

exercise will manage you how to introduce PHP parser on your PC.

2. MySQL:

MySQL is the most famous Open Source Relational SQL Database Management System.

MySQL is outstanding amongst other RDBMS being utilized for creating different online

programming applications. MySQL is created, advertised and upheld by MySQL AB, which is

a Swedish organization. This instructional exercise will give you a fast begin to MySQL and

make you OK with MySQL programming.

What is a Database?

A database is a different application that stores a gathering of information. Every database has

at least one unmistakable APIs for making, getting to, overseeing, seeking and recreating the

information it holds.

Different sorts of information stores can likewise be utilized, for example, records on the

document framework or vast hash tables in memory yet information getting and composing

would not be so quick and simple with those kind of frameworks.

These days, we utilize social database administration frameworks (RDBMS) to store and

oversee tremendous volume of information. This is called social database since every one of the

information is put away into various tables and relations are set up utilizing essential keys or

different keys known as Foreign Keys.

A Relational DataBase Management System (RDBMS) is a product that:

• Empowers you to execute a database with tables, segments and records.



• Ensures the Referential Integrity between columns of different tables.



• Updates the lists naturally.



• Deciphers a SQL inquiry and consolidates data from different tables.

RDBMS Terminology

Before we continue to clarify the MySQL database framework, let us modify a couple of

definitions identified with the database.

AISSMS COE, PUNE Page 43

Web Technology Lab Manual

• Database: A database is a gathering of tables, with related information.



• Table: A table is a grid with information. A table in a database resembles a basic

spreadsheet.



• Column: One section (information component) contains information of one and a similar

kind, for instance the segment postcode.



• Row: A line (= tuple, passage or record) is a gathering of related information, for

instance the information of one membership.



• Redundancy: Storing information twice, needlessly to make the framework quicker.



• Essential Key: An essential key is exceptional. A key esteem can not happen twice in

one table. With a key, you can just discover one column.



• Outside Key: A remote key is the connecting pin between two tables.



• Compound Key: A compound key (composite key) is a key that comprises of numerous

sections, since one segment isn't adequately exceptional.



• Index: A file in a database looks like a file at the back of a book.



• Referential Integrity: Referential Integrity ensures that an outside key esteem dependably

indicates a current column.

MySQL Database

MySQL is a quick, simple to-utilize RDBMS being utilized for some little and huge

organizations. MySQL is produced, showcased and upheld by MySQL AB, which is a Swedish

organization. MySQL is winding up so famous as a result of numerous great reasons:

• MySQL is discharged under an open-source permit. So you don't have anything to pay to

utilize it.



• MySQL is a capable program in its own particular right. It handles a huge subset of the

usefulness of the most costly and intense database bundles.



• MySQL utilizes a standard type of the outstanding SQL information dialect.



• MySQL takes a shot at many working frameworks and with numerous dialects including

PHP, PERL, C, C++, JAVA, and so forth.



• MySQL works rapidly and functions admirably even with extensive informational

indexes.



• MySQL is amicable to PHP, the most refreshing dialect for web advancement.



• MySQL underpins huge databases, up to 50 million lines or more in a table. The default

document measure restrain for a table is 4GB, yet you can expand this (if your working

framework can deal with it) to a hypothetical utmost of 8 million terabytes (TB).

AISSMS COE, PUNE Page 44

Web Technology Lab Manual

• MySQL is adaptable. The open-source GPL permit enables developers to alter the

MySQL programming to fit their own particular surroundings.

TECHNOLOGY/TOOL

1. Technology is to be used is PHP (PHP Hypertext Preprocessor) and tool XAMPP server is to

be used to execute PHP web application.

2. XAMPP server embeds the PHP, MySQL and phpmyadmin, these three tools must be

required to run php web application.

DESIGN/EXECUTION STEPS

For the design purpose html and CSS is to be used. For this design part contains the GUI of web

applications, how its looks like? When users going to use the web application.

Steps to install XAMPP and configure the PHP, MYSQL server.

1. Download the XAMPP using following link (download latest version as per your Operating

system Windows/ Linux). Here we are using Linux Ubuntu Systems. Copy and paste downloaded

XAMPP into home location. https://www.apachefriends.org/download.html

2. Install XAMPP with following command in terminal(copy paste the command).

sudo ./xampp-linux-x64-7.2.0-0-installer.run

3. After ab

4. ove command following installation window will appear.

8. To navigate to htdocs

cd opt/lampp/htdocs

9. To create a file hello.php

gedit hello.php

Code for Sample Hello Script

<?php

echo(“Hello, Welcome to First PHP Application”);

10. Now go to your browser then type localhost/filename.php

11. Open phpmyadmin to create MySQL database

type in browser URL “localhost/phpmyadmin” you will see following window.

Here you can create the database and table inside database as per your need.Here we created “test”

database with “users” table contain four columns.

THEORY-CONCEPT

AJAX remains for Asynchronous JavaScript and XML. AJAX is another procedure for making

better, speedier, and more intelligent dynamic web applications with the assistance of XML, HTML,

CSS, and Java Script. Ajax utilizes XHTML for content, CSS for introduction, alongside Document

Object Model and JavaScript for dynamic substance show.

Customary web applications transmit data to and from the server utilizing synchronous solicitations.

It implies you round out a frame, hit submit, and get coordinated to another page with new data from

the server. With AJAX, when you hit submit, JavaScript will influence a demand to the server, to

decipher the outcomes, and refresh the present screen. In the purest sense, the client could never

realize that anything was even transmitted to the server.

AJAX instructional exercise covers ideas and cases of AJAX innovation for apprentices and experts.

AJAX is an acronym for Asynchronous JavaScript and XML. It is a gathering of between related

innovations like JavaScript, DOM, XML, HTML, CSS and so forth.

AJAX enables you to send and get information nonconcurrently without reloading the page. So it is

quick.

AJAX enables you to send just essential data to the server not the whole page. So just profitable

information from the customer side is steered to the server side. It makes your application intuitive

and quicker.

AJAX speaks with the server utilizing XMLHttpRequest question. How about we endeavor to

comprehend the stream of ajax or how ajax functions by the picture showed beneath.

AJAX communicates with the server using XML Http Request object. Let's try to understand the

flow of ajax or how ajax works by the image displayed below:

TITLE

Design and develop any web application using Struts framework.

OBJECTIVES

1. To impart the efficient and available client side and server side technologies.

2. To implement the communication between computing nodes using client side and server

side technologies.

3. To design and implement the web services with content management.

PROBLEM STATEMENT

Create a login module for the web application using struts framework.

OUTCOMES

Students should be able to,

1. Implement the effective client side and server side technologies using struts framework.

2. Solve the complex problem of development using MVC framework.

SOFTWARE & HARDWARE REQUIREMENTS

Software’s: Java 1.7 or Higher, Apache Tomcat 7 or higher, Struts API’s, Eclipse IDE.

THEORY

The frameworks plays a vital role in industries for manageable and well designed application

development as well as enterprise application development. The core of the Struts framework is a flexible

control layer based on standard technologies like Java Servlets, JavaBeans, Resource Bundles, and XML,

as well as various Jakarta Commons packages. Struts encourages application architectures based on the

Model 2 approach, a variation of the classic Model-View-Controller(MVC)

AISSMS COE, PUNE Page 71

Web Technology Lab Manual

Struts gives its own particular Controller segment and incorporates with different advancements to give

the Model and the View. For the Model, Struts can collaborate with standard information get to advances,

as JDBC and EJB, and also most any outsider bundles, as Hibernate, iBATIS, or Object Relational

Bridge. For the View, Struts functions admirably with Java Server Pages, including JSTL and JSF, and in

addition Velocity Templates, XSLT, and other introduction frameworks.

The Struts system gives the undetectable underpinnings each expert web application needs to survive.

Struts causes you make an extensible advancement condition for your application, in view of distributed

guidelines and demonstrated outline designs.

ORM remains for Object/Relational mapping. It is the customized and translucent constancy of items in a

Java application in to the tables of a social database utilizing the metadata that portrays the mapping

between the articles and the database. It works by changing the information starting with one portrayal

then onto the next.

The Model-View-Controller Architecture

"Model-View-Controller" is a way to build applications that promotes complete separation

between business logic and presentation. It is not specific to web applications, or Java, or J2EE

(it predates all of these by many years), but it can be applied to building J2EE web applications.

AISSMS COE, PUNE Page 72

Web Technology Lab Manual

Figure.5: Basic MVC Architecture.

The "view" is the user interface, the screens that the end user of the application actually sees and

interacts with. In a J2EE web application, views are JSP files. For collecting user input, you will

have a JSP that generates an HTML page that contains one or more HTML forms. For displaying

output (like a report), you will have a JSP generates an HTML page that probably contains one

or more HTML tables. Each of these is a view: a way for the end user to interact with the system,

putting data in, and getting data out.

What is Struts?

Struts is a framework that advances the utilization of the Model-View-Controller engineering for

planning substantial scale applications. The structure incorporates an arrangement of custom

label libraries and their related Java classes, alongside different utility classes. The most intense

part of the Struts system is its help for making and preparing electronic structures. We will

perceive how this functions later in this section.

Struts Tags

Common Attributes

Almost all tags provided by the Struts framework use the following attributes:

AISSMS COE, PUNE Page 73

Web Technology Lab Manual

Attribute

Used for

the name of a bean for temporary use by the tag

name

the name of a pre-existing bean for use with the tag

property

the property of the bean named in the name attribute for use with the tag

scope

the scope to search for the bean named in the name attribute

Table.2: Struts Framework Attributes

Creating Beans

Beans are created by Java code or tags.

Here is an example of bean creation with Java code:

// Creating a Plumber bean in the request scope

Plumber aPlumber = new Plumber();

request.setAttribute("plumber", aPlumber);

Beans can be created with the <jsp:useBean></jsp:useBean> tag:

<!-- If we want to do <jsp:setProperty ...></jsp:setProperty> or --

>

<jsp:useBean id="aBean" scope="session" class="java.lang.String">

creating/using a bean in session scope of type java.lang.String

</jsp:useBean>

Most useful is the creation of beans with Struts tags:

<bean:define id="greenBean" value="Here is a new constant string bean; pun intended."/>

<bean:define id="lima" name="frijole"/>

<bean:define id="lima" name="frijole" class="com.SomePackageName.Beans.LimaBean"/>

<bean:define id="goo" name="foo" property="geeWhiz" scope="request" toScope="application"/>

Other Bean Tags

The Struts framework provides other tags for dealing with issues concerning copying cookies,

request headers, JSP implicity defined objects, request parameters, web application resources,

AISSMS COE, PUNE Page 74

Web Technology Lab Manual

Struts configuration objects, and including the dynamic response data from an action. These tags

are not discussed here, but it is important to be aware of their existence.

<bean:cookie ... >

<bean:header ... >

<bean:page ... >

<bean:parameter ... >

<bean:header ... >

<bean:resource ... >

<bean:struts ... >

Bean Output

The <bean:message> and <bean:write> tags from the Struts framework will write bean and aplication

resources properties into the current HttpResponse object.

This tag allows locale specific messages to be displayed by looking up the

message in the application resources .properties file.

<!--

looks up the error.divisionByZero resource -->

<!--

and writes it to the HttpResponse object --

<bean:message ... >

<bean:message key="error.divisionByZero"/>

<!--

looks up the prompt.name resource -->

<!--

and writes it to the HttpResponse object; --

<!--

failing that, it writes the string

-->

<!--

contained in the attribute arg0--

<bean:message key="prompt.name" arg0='Enter a name:'/>

This tag writes the string equivalent of the specified bean or bean property to

the current HttpResponse object.

<bean:write ... > <!-- writes the value of customer.getStreetAddress().toString() --

>

<bean:write name="customer" property="streetAddress"/>

Creating HTML Forms

Frequently data should be gathered from a client and handled. Without the capacity to gather

client input, a web application would be futile. So as to get the clients data, a html shape is

utilized. Client information can originate from a few gadgets, for example, content fields, content

boxes, check takes care of, pop menus, and radio catches. The information comparing to the

AISSMS COE, PUNE Page 75

Web Technology Lab Manual

client input is put away in an ActionForm class. A design document called struts-config.xml is

utilized to characterize precisely how the client input are handled. The following diagram

roughly depicts the use of Struts for using forms.

Figure.6: Struts for Using Forms

The Struts html tags are used to generate the widgets in the html that will be used in gathering

the user’s data. There are also tags to create a form element, html body elements, links, images,

and other common html elements as well as displaying errors. Below are the tags provided by

html section of the Struts framework and a short description of each.

<html:base>

<html:button>

<html:cancel>

<html:checkbox>

<html:multibox>

Generates a <base> tag. This tag should be used inside of a <head>

tag.

Generates an <input type="button"> tag. This tag should be used inside

a <form> element.

Generates an <input type="submit"> tag and causes the Action servlet

not to invoke its validate() method. This tag should be used inside a

<form> element.

Wheat Wood Clay

Stone Sheep

<html:checkbox> Generates an <input type="checkbox">.

<html:multibox> Generates an <input type="checkbox">. "Checkedness"

AISSMS COE, PUNE Page 76

Web Technology Lab Manual

<html:errors>

<html:file>

<html:form>

<html:hidden>

The ActionForm class

depends upon whether the property array specified contains a

corresponding value as the one specified for the multibox.

Generates html to display any errors that may have occurred during

invocation of the validate() method.

Generates <form>.

There is a hidden element here which is invisible. :-)

Generates <input type="hidden">.

The purpose of the ActionForm class is to contain and provide validation of the user-input data.

This class is subclassed for application specific customization.

Here is a template for a customized ActionForm class with markers denoting where special items

should be located in the class with $ symbols.

package com.akurdi.action;

import com.opensymphony.xwork2.ActionSupport;

public class LoginAction extends ActionSupport {

private String username;

private String password;

public String execute() {

if(this.username == null || this.password == null)

{

return "error";

}

if (this.username.equals("admin")

&& this.password.equals("admin123")) {

return "success";

AISSMS COE, PUNE Page 77

Web Technology Lab Manual

} else {

addActionError(getText("error.login"));

return "error";

}

public String getUsername() {

return username;

}

public void setUsername(String username) {

this.username = username;

}

public String getPassword()

{

return password;

}

public void setPassword(String password) {

this.password = password;

}

Do this:

1. Create the directory structure. The root directory is SimpleStruts, and it has the standard

WEB-INF directory with classes inside, and com.akurdi.action inside that. It also has a lib

directory within WEB-INF, which is something we haven't seen before; we'll see in a

minute what goes there.

AISSMS COE, PUNE Page 78

Web Technology Lab Manual

2. Copy the Struts tag library descriptor files into WEB-INF. The files struts.tld, struts-bean.tld,

struts-form.tld, struts-html.tld, struts-logic.tld, and struts-template.tld are available in the lib

directory of your Struts installation.

3. Copy the Struts parser, struts.jar, into WEB-INF/lib/. This file is available in the lib directory

of your Struts installation

4. Create the tag descriptor library file for any custom tags you may use beyond the Struts

tags. In this case, the file defines no custom tags, but it's good practice to have it in place,

in case you need to add your own tags later.

5. Create the struts-config.xml file.

There are three main sections to a struts-config.xml configuration file. They are the "Form

Bean Definitions" section, the "Global Forward Definitions" section, and the "Action

Mapping Definitions" section defines a forward called "success".

6. Create the web.xml file.

The web.xml web application configuration file will need to define the servlet ActionServlet,

to which control will be transferred whenever an appropriate URL pattern is accessed.

The servlet is defined just as any other servlet will be defined. The URL pattern is

specified by a servlet mapping. For this application, the URL pattern is any requested

resource that ends with a .do extension.

In order to use the Struts tags, the .tld files describing the tags will need to be included in

the configuration file. The references to these tags are made just as they were for our

own custom tags in the previous chapter. The Struts framework is simply a complex set

of tag libraries (struts*.tld), with associated code (struts.jar).

7. The ApplicationResources.properties file provides resources that will be used by any subclassed

Struts classes (for example, SetNameAction). This resources file provides a place to define

prompts, labels that will display on buttons, and other information that may change. By

placing this information in the ApplicationResources.properties file, recompiling any servlets

used in the application can be avoided, as well as encouraging separation of logic and

presentation.

8. Instances of the Name class are placed in the user sessions. Only one will exist in any

particular user session. It provides methods for accessing and mutating a name.

9. The view of the application is done with the JSP index.jsp. It represents the user interface

and allows the user to interact with the application.

10. Compile, create .war file and place it into the webapps folder of tocat.

AISSMS COE, PUNE Page 79

Web Technology Lab Manual

11. Go to http://localhost:8080/Sturtsdemo/example/Login.jsp to test your application

TECHNOLOGY/TOOL

1) Eclipse IDE

2) Apache Tomcat 7.0 or higher

DESIGN/EXECUTION STEPS

Step 1) Create the directory structure as

Step 2) Create input page as below.

Step 3) Provide the entry of Controller in (web.xml) file as given above

Step 4) Create the action class (LoginAction.java)

Step 5) Map the request in (struts-config.xml) file and define the view components.

Step 6) Load the jar files

Step 7) start server and deploy the project or create .war file paste it in webapps folder and run

from manager-app.

TEST CASES

1. Manual test cases need to be performed on struts application.

2. Check whether the tomcat server is running.

3. Check whether the application running status in manager app list is true.

4. Run the application by selecting the app in the list.

5. Check whether the application giving desired results.

THEORY-CONCEPT

AngularJS is an open-source web application framework. It was initially created in 2009 by

MiskoHevery and Adam Abrons. It is presently kept up by Google. Its most recent adaptation is

1.2.21. "AngularJS is an auxiliary system for dynamic web applications. It gives you a chance to

AISSMS COE, PUNE Page 82

Web Technology Lab Manual

utilize HTML as your layout dialect and gives you a chance to stretch out HTML's linguistic

structure to express your application parts plainly and compactly. Its information official and

reliance infusion take out a significant part of the code you as of now need to compose. Also,

everything occurs inside the program, making it a perfect band together with any server

innovation".

General Features

• AngularJS is a productive system that can make Rich Internet Applications (RIA).



• AngularJS gives designers a choices to compose customer side applications utilizing

JavaScript in a spotless Model View Controller (MVC) way.



• Applications written in AngularJS are cross-program agreeable. AngularJS consequently

handles JavaScript code reasonable for every program.



• AngularJS is open source, totally free, and utilized by a great many engineers the world

over. It is authorized under the Apache permit version2.0.



• By and large, AngularJS is a system to assemble expansive scale, elite, and simple to-

keep up web applications.

Core Features:

Figure.7: Architecture of AngularJS

1. Data-authoritative: It is the programmed synchronization of information amongst model

and view parts.

AISSMS COE, PUNE Page 83

Web Technology Lab Manual

2. Scope: These are objects that allude to the model. They go about as paste amongst

controller and view.

3. Controller: These are JavaScript capacities bound to a specific degree.

4. Services: AngularJS accompanies a few implicit administrations, for example, $http to

make aXMLHttpRequests. These are singleton objects which are instantiated just once in

application.

5. Filters: These select a subset of things from a cluster and restore another exhibit.

6. Directives: Directives are markers on DOM components, for example, components,

characteristics, css, and that's only the tip of the iceberg. These can be utilized to make

custom HTML labels that fill in as new, custom gadgets. AngularJS has worked in

mandates, for example, ngBind, ngModel, and so on.

7. Templates: These are the rendered see with data from the controller and model. These

can be a solitary record, (for example, index.html) or different perspectives in a single

page utilizing partials.

8. Routing: It is idea of exchanging sees.

9. Model View Whatever: MVW is an outline design for isolating an application into

various parts called Model, View, and Controller, each with unmistakable obligations.

AngularJS does not actualize MVC in the conventional sense, yet rather something nearer

to MVVM (Model-View-ViewModel). The Angular JS group alludes it cleverly as

Model View Whatever.

10. Deep Linking: Deep connecting permits to encode the condition of use in the URL with

the goal that it can be bookmarked. The application would then be able to be re-

established from the URL to a similar state.

AISSMS COE, PUNE Page 84

Web Technology Lab Manual

11. Dependency Injection: AngularJS has a worked in reliance infusion subsystem that

encourages the designer to make, comprehend, and test the applications effectively.

Advantages of AngularJS

• It gives the ability to make Single Page Application in a spotless and viable way.



• It gives information restricting ability to HTML. Along these lines, it gives client a rich

and responsive experience.



• AngularJS code is unit testable.



• AngularJS utilizations reliance infusion and make utilization of partition of concerns.



• AngularJS gives reusable segments.



• With AngularJS, the engineers can accomplish greater usefulness with short code.



• In AngularJS, sees are unadulterated html pages, and controllers written in JavaScript do

the business handling.

Model View Controller

Model View Controller or MVC as it is famously called, is a product configuration design for

creating web applications. A Model View Controller design is comprised of the accompanying

three sections.

• Model − It is the most minimal level of the example in charge of looking after

information.



• View − It is in charge of showing all or a part of the information to the client.



• Controller − It is a product Code that controls the connections between the Model and

View.

MVC is mainstream since it secludes the application rationale from the UI layer and backings

detachment of concerns. The controller gets all solicitations for the application and afterward

works with the model to set up any information required by the view.

AISSMS COE, PUNE Page 85

Web Technology Lab Manual

Figure. 8: Model View Controller

Model

The model is in charge of overseeing application information. It reacts to the demand from see

and to the directions from controller to refresh itself.

The View

An introduction of information in a specific arrangement, activated by the controller's choice to

exhibit the information. They are content based layout frameworks, for example, JSP, ASP, PHP

and simple to incorporate with AJAX innovation.

The Controller

The controller reacts to client enter and performs communications on the information show

objects. The controller gets input, approves it, and afterward performs business operations that

alter the condition of the information demonstrate.

AngularJS is a MVC based structure.

• An AngularJS application comprises of following three essential parts −ng-app −

This directive defines and links an AngularJS application to HTML.

AISSMS COE, PUNE Page 86

Web Technology Lab Manual

• ng-model − This directive binds the values of AngularJS application data to HTML

input controls.

• ng-bind − This directive binds the AngularJS Application data to HTML tags.

DESIGN/EXECUTION STEPS

Steps for AngularJS

1. When a link https://angularjs.org/ is opened, there are two options to download AngularJS

library −

• View on GitHub − Click on this button to go to GitHub and get all of the latest scripts.



• Download AngularJS 1 − Or click on this button, a screen as below would be seen −

• This screen gives various options of using Angular JS as follows:

AISSMS COE, PUNE Page 87

Web Technology Lab Manual

• Downloading and hosting files locally

1. There are two different options legacy and latest. The names itself are self-descriptive.

Legacy has version less than 1.2.x and latest has 1.5.x version.

2. We can also go with the minified, uncompressed or zipped version.

• CDN access − You also have access to a CDN. The CDN will give you access around

the world to regional data centers that in this case, Google host. This means using CDN

moves the responsibility of hosting files from your own servers to a series of external

ones. This also offers an advantage that if the visitor to your webpage has already

downloaded a copy of AngularJS from the same CDN, it won't have to be re-

downloaded.

Example:

Now let us write a simple example using AngularJS library. Let us create an HTML file

myfirstexample.html as below –

<!doctype html>

<html>

<head>

<scriptsrc="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.2/angular.min.js"></script>

</head>

<bodyng-app="myapp">

<divng-controller="HelloController">

<h2>Welcome {{helloTo.title}} to the world of

Tutorialspoint!</h2> </div>

angular.module("myapp",[])

.controller("HelloController",function($scope){

AISSMS COE, PUNE Page 88

Web Technology Lab Manual

$scope.helloTo={};

$scope.helloTo.title="AngularJS";

});

</script>

</body>

</html>

Following sections describe the above code in detail:

1. Include AngularJS

We have included the AngularJS JavaScript file in the HTML page so we can use AngularJS −

<head>

<scriptsrc="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>

</head>

To update into latest version of Angular JS, use the following script source.

<head>

<scriptsrc="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.2/angular.min.js"></script>

</head>

2. Point to AngularJS app

Next we tell what part of the HTML contains the AngularJS app. This done by adding the ng-

app attribute to the root HTML element of the AngularJS app. You can either add it to html

element or body element as shown below −

<bodyng-app="myapp">

</body>

3. View

The view is this part −

<divng-controller="HelloController">

<h2>Welcome {{helloTo.title}} to the world of Tutorialspoint!</h2>

AISSMS COE, PUNE Page 89

Web Technology Lab Manual

</div>

ng-controller tells AngularJS what controller to use with this view. helloTo.titletells AngularJS

to write the "model" value named helloTo.title to the HTML at this location.

4. Controller

The controller part is −

angular.module("myapp",[])

.controller("HelloController",function($scope){

$scope.helloTo={};

$scope.helloTo.title="AngularJS";

});

</script>

This code registers a controller function named HelloController in

the angularmodule

named myapp. The controller function is registered in angular via the

angular.module(...).controller(...) function call.

The $scope parameter passed to the controller function is the model. The controller function

adds a helloTo JavaScript object, and in that object it adds a title field.

5. Execution

Save the above code as myfirstexample.html and open it in any browser.

Output as below:

Welcome AngularJS to the world of Tutorialspoint!

• At the point when the page is stacked in the program, following things happen −



• HTML archive is stacked into the program, and assessed by the program. AngularJS

JavaScript document is stacked, the precise worldwide question is made. Next,

JavaScript which registers controller capacities is executed.

AISSMS COE, PUNE Page 90

Web Technology Lab Manual

• Next AngularJS look over the HTML to search for AngularJS applications and

perspectives. When see is found, it associates that view to the comparing controller work.



• Next, AngularJS executes the controller capacities. It at that point renders the

perspectives with information from the model populated by the controller. The page is

presently prepared.



6. How AngularJS integrates with HTML

• ng-app directive indicates the start of AngularJS application.



• ng-model directive then creates a model variable named "name" which can be used with

the html page and within the div having ng-app directive.



• ng-bind then uses the name model to be displayed in the html span tag whenever user

input something in the text box.



• Closing</div> tag indicates the end of AngularJS application.

AngularJS directives are used to extend HTML. These are special attributes starting with ng-

prefix. We're going to discuss following directives −

• ng-app − This directive starts an AngularJS Application.



• ng-init − This directive initializes application data.



• ng-model − This directive binds the values of AngularJS application data to HTML

input controls.

• ng-repeat − This directive repeats html elements for each item in a collection.

TECHNOLOGY/TOOL

Any IDE or you can use web browser.

TEST CASES

Deploy the Html program run test the result for dynamic implementation of AngularJS.

CONCLUSION/ANALYSIS

With the help of this assignment it is helpful to understand features of AngularJS. MVC

model structure and its use in advanced web programming is studied.

THEORY – CONCEPT

Java Beans :

J2EE application container contains the components that can be used by the clients for executing

the business logic .These components are known as Enterprise Java Beans (EJB) .

J2EE platform has component based architecture to provide multi-tiered, distributed and highly

transactional features to enterprise level applications.

EJB mainly contains the business logic & business data. EJB component is an EJB class. It is a

java class written by EJB developer & this class implements business logic.

It is used for developing very much scalable and robust enterprise level applications to be

deployed Application Server such as JBOSS, Web Logic etc.

EJB 3.0 is being a large shift from EJB 2.0 and makes development of EJB based applications

relatively easy.

Features of EJBs:

Some of the features of an application server include the following:

• Client Communication: The client, which is often a user interface, must be able to call the

methods of objects on the application server via agreed-upon protocols.

• State Management: You'll recall our discussions on this topic in the context of JSP

(JavaServer Pages) and servlet development back in Chapter 6.

• Transaction Management: Some operations, for example, when updating data, must

occur as a unit of work. If one update fails, they all should fail.

• Database Connection Management: An application server must connect to a database,

often using pools of database connections for optimizing resources.

• User Authentication and Role-Based Authorization: Users of an application must

often log in for security purposes. The functionality of an application to which a user is

allowed access is often based on the role associated with a user ID.

• Asynchronous Messaging: Applications often need to communicate with other systems

in an asynchronous manner; that is, without waiting for the other system to respond. This

requires an underlying messaging system that provides guaranteed delivery of these

asynchronous messages.

• Application Server Administration: Application servers must be administered. For

example, they need to be monitored and tuned.

AISSMS COE, PUNE Page 98

Web Technology Lab Manual

Types of Enterprise Java Beans (EJB):

There are three types of Enterprise Java Beans namely:

1. Session Beans

2. Entity Beans

3. Message driven beans

Session Beans

• Session beans are intended to allow the application author to easily implement portions of

application code in middleware and to simplify access to this code.

• Represents a single client inside the server

• The client calls the session bean to invoke methods of an application on the server

• Perform works for its client, hiding the complexity of interaction with other objects in the

server

• Is not shared

• Is not persistent

When the client stops the session, the bean can be assigned to another client from the server

Session beans are divided into two types:

1. Stateless Session Bean:

Stateless Session Bean is intended to be simple and “light weight” components. The client,

thereby making the server highly scalable, if required, maintains any state. Since no state is

maintained in this bean type, stateless session beans are not tied to any specific client, hence any

available instance of a stateless session bean can be used to service a client.

• values only for the duration of the single invocation

• Except during method invocation, all instances of

stateless session bean are equivalent

Stateless Session Bean’s Life Cycle:

• The client invoke the create method

• The EJB container :

Instantiates the bean

Invokes the setSessionContext Invokes ejbCreate

• The bean is ready

• While in the ready state

Web Technology Lab Manual

Exist

2. ejbcrete

ejbRemove

Ready

Figure.9: Stateless Session Bean’s Life Cycle

client may invoke a business method :

A client may invoke the remove method and the container calls the bean's ejbRemove method

It’s never passivate .

2. Stateful Session Bean:

State ful Session Bean provides easy and transparent state management on the server side.

Because state is maintained in this bean type, the application server manages client/bean pairs.

Stateful session beans can access persistent resources on behalf of the client, but unlike entity

beans, they do not actually represent the data.

Stateful Session Beans Life Cycle:

• The client invoke the create method

• The EJB container :

Instantiates the bean

• The bean is ready

• While in the ready state

• container may passivate the bean moving it from memory to secondary storage

•

• A client may invoke a business method

EJB container may activate a bean, moving it back to the ready stage, and then calls the bean's

ejbActivate method.

A client may invoke the remove method and the container calls the bean's ejbRemove method

Difference Between Stateless and State Full EJB Are as Follows

Stateless:

1. Normally data members are not put in stateless session bean

2. Stateless beans are pooled

AISSMS COE, PUNE Page 100

Web Technology Lab Manual

3. No effort for keeping client specific data

4. No Activation/Passivation in stateless session bean

Stateful:

1. Data members that represent state are present in stateleful session bean

2. Stateful beans are cached

3. Setting the tag idle-timeout-seconds determines how long data is maintained in stateful

session bean

4. Activation – Passivation used

An Entity Bean

• An entity bean is an object representation of persistent data maintained in a permanent data

store such as a database. A primary key identifies each instance of an entity bean. Entity

beans are transactional and are recoverable in the event of a system crash.

• Entity beans are representations of explicit data or collections of data, such as a row in a

relational database. Entity bean methods provide procedures for acting on the data

representation of the bean. An entity bean is persistent and survives if its data remains in the

database.

• An entity bean can implement either bean-managed or container-managed persistence. In the

case of bean-managed persistence, the implementer of an entity bean stores and retrieves the

information managed by the bean through direct database calls. The bean may utilize either

Java Database Connectivity (JDBC) or SQL-Java (SQLJ) for this method.

• In the case of container-managed persistence, the container provider may implement access

to the database using standard APIs. The container provider can offer tools to map instance

variables of an entity bean to calls to an underlying database. The container saves the data.

There is no code in the bean for access the database. The container handles all database

access required for the bean which create links between beans are created using a structure

called abstract schema.

Enterprise Java Beans (EJB) Architecture

The EJB architecture is an extension of Web architecture. It has an additional tier. The clients of

an enterprise bean can be a traditional java application lie, applet, JSP or Servlet.

Like in a web application, client browser has to go all the way to web container to use a servlet

or JSP, the communication between beans and clients is performed by the EJB container.

The following are the flows of the EJB architecture.

• The client is working on a web browser.



• There is a database server that hosts a database, like MySQL /Oracle.

AISSMS COE, PUNE Page 101

Web Technology Lab Manual

• The J2EE server machine is running on an application server



• The client interface is provided with JSP/Servlet. The enterprise beans reside in the

business tier providing to the client tier.



• The Application Server manages the relationships between the client and database

machines.

Figure.10: EJB Architecture



• In a diagram, an enterprise bean is a non-visual component of a distributed, transaction-

oriented enterprise application. Enterprise beans are typically deployed in EJB containers

and run on EJB servers.

There are three types through which two or more activities may interfere:

1. Dirty read

2. Non-Repeatable read

3. Phantom read

• Clustering and Load-Balancing: Clustering is the process of combining the multiple

peripherals, computers and other resources into a single unit.



• A clustered system then works as load balanced system. In a distributed system when a

request is send to the server, an algorithm running on the server decides which server has

less load and sends the request to that server. EJB container encapsulates these features to

provide smooth and efficient service.



• Deployment Descriptor: A deployment descriptor is an XML file packaged with the

enterprise beans in an EJB JAR file or an EAR file. It contains metadata describing the

contents and structure of the enterprise beans, and runtime transaction and security

information for the EJB container.



• EJB Server: An EJB server is a high-level process or application that provides a run-

time environment to support the execution of server applications that use enterprise

beans. An EJB server provides a JNDI-accessible naming service. It manages and

coordinates the allocation of resources to client applications, provides access to system

resources and provides a transaction service.
