Agenda

z Web Technologies (7:10 p.m. – 8:00 p.m.) – HTTP – HTML – Web Applications

– Components of Web Applications – Q&A

z Break (8:00 p.m. – 8:15 p.m.)

(3)

HTTP

z Internet can be described as the largest

client-server system

z The clients are “Web Browser” z The servers are “Web Server”

z Protocol used is HTTP( Hyper Text Transfer

Protocol).

z HTTP is a request-response protocol

– client sends request to the server in specific format

– Server responds to the request by sending a specific file

(4)

HTML

z Stands for Hyper Text Markup Language

z Interpreted language rather than a compiled

language

z Platform independent

z Follows certain standards imposed by W3C z Consists of tags also referred as markups to

(5)

HTML (contd.)

<HTML>

<HEAD><TITLE> Demo HTML </TITLE> </HEAD>

<BODY>

<P> PERSONAL DETAILS</P> </BODY>

(6)

Web Applications

z Collection of web pages is called a web site

z Websites display static content and allows user

to navigate and view information

z Web applications provide a more interactive

experience to the user by generating dynamic content

z Web apps are created to solve specific problems

for the user. Examples: Applications like My Yahoo or a Web store front software

(7)

Web Applications (contd.)

z Web applications are the integration of different

components:

– Web Servers

– Application Servers

– Server Side Scripts( either Java, Microsoft or others) – Client side scripts (Java scripts, VB scripts)

– Databases( Oracle, Mysql, DB2) – Data Interchange

• XML

• Text

– Security components like SSL, S-HTTP, Certificates – Payment Infrastructure Software

(8)

Quiz

z Is Hotmail a web application?

z Is the IEEE website a web application? z Is Yahoo’s website a B2C or B2B

(9)

Java and the Web

(10)

Java Servlets

z Java Servlets are the java class files which

execute within the process space of the application server

z Needs servlet engines to execute them z They are portable across multiple

platforms

(11)

Java Servlets (contd.)

z Servlets are dynamically loaded modules

that service request from the web server

servlet

Client

web server Application server

(12)

Java Server Pages

-

JSP

z They are simple way of generating the

dynamic HTML on the server side

z They are extension of the Java Servlets

and provide a way to separate content generation from content presentation

z Looks like any HTML code with java code

embedded in it between <% %>

(13)

Java Server Pages (contd.)

z JSP Directives

– Page Directive: Can be used to control the following

• Sessions

• Library usage

• Scripting language

• Mime types

• Error Page

• Usage: <%@ page import="java.util.*,java.text.*" %>

– Include Directive: Allows to include the contents of

(14)

Group Question

z What is the difference between JSP and

Servlet?

– To the end user? – To the developer?

(15)

JSPs vs. Servlets

z They are the same to the end user

z JSPs are always converted to servlets

z JSPs allow for the content presentation to

be separated from business logic. Servlets don’t

(16)

Microsoft Technologies and Web

(17)

Active Server Pages

-

ASP

z Very similar to JSP - another way to generate

dynamic HTML.

z Open, compile-free application environment

z ASP can be combined with reusable components

like ActiveX to create dynamic and Web-based business solutions.

z Active Server Pages enable server-side scripting

(18)

Active Server Pages (contd.)

z Looks like any HTML code with VB script

embedded in it between <% %>

z ASPs were initially designed to work with

I.I.S.

z With Sun ONE Active Server Pages it can

be made to run on the Apache Web Server and SUN ONE WEB server. More

(19)

ASP (contd.)

Sample Code <html> <head> <Title>Hi there!</title> </head>

<body background="" bgColor=#ffffff> <h2>

<%

Response.Write "Welcome to Web and eTechnologies Seminar"

(20)

.NET

z Set of software technologies

z Removes different barriers between the

systems, user through web services

z Uses the .NET Application Framework z .NET Application Framework has 2

components

(21)

Data Interchange Technologies

(22)

X.M.L.

z Stands for Extensible Markup Language. z Designed to be universal format for data

on the web

z XML allows developers to easily describe

structured data from any application in a standard way

z XML doesn’t replace HTML. Is is rather

(23)

X.M.L. (contd.)

z Is self describing and doesn’t have any

predefined tags. This makes it easy for applications to exchange data following the same protocol

z XML can be used to define other

languages like WML (wireless markup language)

(24)

XML (contd.)

z Sample XML file. <Student> <StudentId>S001</StudentId> <FirstName>Marwan</FirstName> <LastName>Forzley</LastName> <Age>10</Age> </Student>

(25)

Security

(26)

Security (S.S.L.)

(27)

Group Exercise

z Where would you use the following

technologies: – Html

– Java Servlets / JSPs/ASPs – SSL
