c. Proper Dress code and Identity card.
4. Sign in the laboratory login register, write the TIME-IN, and occupy the computer
system allotted to you by the faculty.
5. Execute your task in the laboratory, and record the results / output in the lab
observation note book, and get certified by the concerned faculty.
6. All the students should be polite and cooperative with the laboratory staff, must
maintain the discipline and decency in the laboratory.

WEEK 1:
Design the following static web pages required for an online book store web site.
1) HOME PAGE: The static home page must contain three frames.
2) LOGIN PAGE
3) CATOLOGUE PAGE: The catalogue page should contain the details of all the books
available in the web site in a table.
4) REGISTRATION PAGE

Aim: Design the following static web pages required for online book store.
1. Home page:- the static home page must contains three pages
2. Top frame:- logo and college name and links to homepage, login page, registration page
and catalogue page
3. Left frame:- at least four links for navigation which will display the catalogue of
Respective links
4. Right frame:- the pages to links in the left frame must be loaded here initially it Contains
the description of the website.
DESCRIPTION: In this program the entire web paged are created by using basic HTML
tags. Home page is divided into 3 frames by using <frameset> and <frame> tags. A frame is
used to display a web page within a web page.
<frameset>:
 The <frameset> tag defines a frameset.
 The <frameset> element holds one or more <frame> elements.
 Each <frame> element can hold a separate document.
 The <frameset> element specifies HOW MANY columns or rows there will be in the
frameset, and HOW MUCH percentage/pixels of space will occupy each of them.
<frame>:
 The <frame> tag defines one particular window (frame) within a <frameset>.
 Each <frame> in a <frameset> can have different attributes, such as border, scrolling,
the ability to resize, etc.
PROGRAM:
home.html:
<frameset rows="40%,*">
<frame src="top.html" noresize scrolling="NO" name="topframe">
<frameset cols="25%,*">
<frame src="left.html" noresize scrolling="NO" name="leftframe">
<frame src="right.html" noresize name="rightframe" scrolling="auto">

WEEK - 10: Implement the web applications with Database using
(a) PHP, (b) Servlets and (c) JSP.

a) A user validation web application, where the user submits the login name &
password to the server. The name and password are checked against the data already
available in Database and if the data matches, a successful login page is returned.
Otherwise failure message is shown to the user.

(c) USING SERVLETS

AIM: Develop Servlet Application of Basic Calculator(+,-,*,/,%) using ServletInputStream
and ServletOutputStream.
DESCRIPTION:
In java with using 2 operant’s and 1 operator we can calculate the basic mathematically
operation such as addition, subtraction, multiplication, division Servlet is a Java class which
extends the capabilities of server that provides the application accessed by means of request
response model. It uses two interfaces i.e. HTTPRequest & HTTPResponse
HTTPRequest: This is an interface which provides methods for extracting HTTP parameters
from the query or request body depending on the type of request i.e. get or post
HTTPResponse: This interface provides an OutputStream for retrieving information such as
images or PrintWriter for retrieving text output.
