JNTU WEB TECHNOLOGIES RECORD MANUAL FOR ENGINEERING STUDENTS
Week-1
Aim: To design the following static web pages required for an online book store website.
HOME PAGEThe static home page must contain three frames.Top frame: Logo and the college name and links to home page, login page, registration page.Catalogue page and Cart page (the description of these pages will be given below).Left frame: At least four links for navigation, which will display the catalogue of respective links.For e.g. when you click the link “CSE” the catalogue for CSE book should be displayed in the Right Frame.Right frame: The page to the link in the left frame must be loaded here. Initially this page contains description of the website.

Cascading Style SheetsAim:
To design a webpage using CSS(cascading style sheet) which includes the followingUse different font, styleIn the style definition you define how each selector should work (font, clor, etc). Then in the body of your pages, you refer to these selectors to activate the styles.
To design a page includes Set a background image for both the page and single element on the page. We can define the background image for the page like BODY{background-image : Url (my image.gif);}
To design a page includes Control the repetition of the image with the background repeat property. As background repeat:repeat. Tiles the image until the entire page is filled, just like an ordinary background image in plain HMTL.
To design a page includes Define styles for links as A:link A:visited A:active A:hover
To design a page that includes work with layers. To design a page includes

Week-6Creating a New Bean:
To create a simple visual bean with area filled with a color. The shape of the area depends on the property shape. If it isset to true then the shape of the
area is square and it is circle if it is false. The color of the area should be changed dynamically for every mouse click. The color should
also be changed if we change the color in the property window.
Program:Colors.javapackage sunw.demo.colors;import java.awt.*;import java.awt.event*;public class Colors extends Canwas{
transient private Color color;private boolean rectangular;public Colors(){
addMouseListener(new MouseAdapter() { public void mousePressed(MouseEvent me) { change(); } }); rectangular=false; setSize(200,100); change();
}public boolean getRectangulat(){
return rectangular;
}public void setRectangular(boolean flag){
this.rectangular=flag; repaint();
}public void change(){

}private Color randomColor(){

public void paint(Grapics g){
Dimention d=getSize(); int h=d.height; int w=d.width; g.setColor(color); if(rectangular) { g.fillRect(0,0,w-l,h-l); } else { g.fillOval(0,0,w-1,h-1); } }}
WEEK-7Installation Of TomcatAim: To write the installation procedure for Tomcat web server and APACHE and while installing use the port number as 8080.
Week-8User AuthenticationAIM:
Assume four users user1, user2, user3 and users having passwords pwd1, pwd2, pwd3&pwd4 respectively. Write a servlet for doing the following:
1. Create a cookie and add these four user ids and passwords to this cookie.2. Read the user id and passwords entered in the login form and authenticate with the
values (user id and passwords) available in the cookies. If be is a valid user (i.e., username and password match) you should Welcome him by name (user-name) else you should display “you are not an authenticated user.

WEEK 9Inserting values into Registration page AIM: Install a database (my sql or oracle)
Create a table which should contain at least the following field:Name, password, email_id, phone number. Practice “JDBC” connectivity. Write a java program [servlet] jsp to connect to that database and extract data from the tables and display them. Experiments with value various sql queries. Insert the details of the uses who register with the website, wherever a new user click the submit button in the registration page.
