WEEK-4

Design a web page using CSS (Cascading Style Sheets) which includes the following

1) Use different font ,styles:

In the style definition you define how each selector should work (font ,color etc.) .Then ,in the body of your pages ,you refer to these selectors to activate the styles.

<html>

09P31A0547

<head><title>css</title>

<style>

h1

{

color:green;

font-family:segoe script;

font-size:20px;

font-weight:15px;

text-decoration:line-through;

text-transform:uppercase;

text-align:center;

}

</style>

<body>

<h1>This is simple style sheet</h1>

</body>

</html>

Output

09P31A0547

2) Set a background image for both the page and single elements on the page.

<html><head><title>css</title>

09P31A0547

<style> body { background-image:url("css.jpg"); background-repeat:no-repeat; background-position:50%; }</style></head><body></body></html>

Output:

3)Control the repetition of the image with the background-repeat property.

<html><head><title>css</title><style>

09P31A0547

body { background-image:url("css.jpg"); background-repeat:repeat; }</style></head><body> </body></html>

Output:

4)Define styles for links as A:link A:visitedA:activeA:hover<html>

09P31A0547

<head><title>css</title><style> a.link{text-decoration:blink}; a.visited{text-decoration:underline}; a.active{text-decoration:line-through}; a.hover{text-decoration:overline};</style></head><body> <a class="visited" href="sample.html"><h2>visited</h2></a><br> <a class="active" href="sample.html"><h2>active</h2></a><br> <a class="hover" href="sample.html"><h2>hover</h2></a><br> <a class="link" href="css.html"><h2>css</h2></a></body></html>

09P31A0547

Output:

09P31A0547

5)Layers

<html><head><title>css</title></head><body><div style="position:relative;font-size:30px;z-index:2;background-color:blue;">layer1</div> <div style="position:relative;top:-50;left:10pt;font-size:60px;z-index:1;color:green;">layer2</div>

<div style="position:relative;font-size:50px;z-index:3;background-color:red;color:white;">layer3</div> <div style="position:relative;top:-50;left:10pt;font-size:80px;z-index:4;">layer4</div></body></html>

Output:

6) Cursors

Week-8User Authentication :Assume four users user1,user2,user3 and user4 having the passwords pwd1,pwd2,pwd3and pwd4 respectively. Write a servelet for doing the following.1. Create a Cookie and add these four user id’s and passwords to this Cookie.2. Read the user id and passwords entered in the Login form (week1) and authenticatewith the values (user id and passwords ) available in the cookies.If he is a valid user(i.e., user-name and password match) you should welcome him byname(user-name) else you should display “ You are not an authenticated user “.

Use init-parameters to do this. Store the user-names and passwords in the webinf.xml and

Week-11Create tables in the database which contain the details of items (books in our case like Bookname , Price, Quantity, Amount )) of each category. Modify your catalogue page (week 2)in sucha way that you should connect to the database and extract data from the tables and display themin the catalogue page using JDBC.

Week-12HTTP is a stateless protocol. Session is required to maintain the state.The user may add some items to cart from the catalog page. He can check the cart page for theselected items. He may visit the catalogue again and select some more items. Here our interest

09P31A0547

is the selected items should be added to the old cart rather than a new cart. Multiple users cando the same thing at a time(i.e., from different systems in the LAN using the ip-address instead oflocalhost). This can be achieved through the use of sessions. Every user will have his ownsession which will be created after his successful login to the website. When the user logs out hissession should get invalidated (by using the method session.invalidate() ).Modify your catalogue and cart JSP pages to achieve the above mentioned functionality usingsessions.
