AIM:

Installing & configuring tomcat webserver

PROCEDURE:

Step 1: Visit Apache Tomcat home page with a Web browser, and click the "Download" link
under the "Tomcat 7.0.70 Released" section. You will see the "Tomcat 7 Downloads"
Step 2: Click "32-bit Windows zip" link under "Binary Distributions" section. You will see the
download file save dialog box.(this supports jdk1.6 kit)
Step 3: Use the "Save file" option to save the download file"apache-tomcat-7.0.70-windows-x86.zip"
to a temporary folder.
Step 4: Unzip "apache-tomcat-7.0.70-windows-x86.zip" to file installation
folder “C:\apache-tomcat-7.0.70”.
Step 5: Try to start Tomcat server by running the "startup" command in a commandline window:
C:\ >cd apache-tomcat-7.0.70\bin
C:\ >cd apache-tomcat-7.0.70\bin>startup
The CATALINA_HOME environment variable is not defined correctlyThisenvironment
variable is needed to run this program
Step 6: To fix the missing environment variables, CATALINA_HOME,JAVA_HOME & JRE_HOME,
● Click my computer->right click properties->Select Advance SystemSetting
● In this tab, Click Environment variable
● Click new in User variables for admin
● Enter variable name & Variable value
▪ CATALINA_HOME C:\apache-tomcat-7.0.70
▪ JAVA_HOME C:\Program Files\Java\
▪ JRE_HOME C:\Program Files\Java\jre7
Step 7: Configuring Tomcat
Open “C:\apache-tomcat-7.0.70\conf”
Folder It consist of the following xml files
Server.xml
Web.xml
Tomcat-
user.xml
Context.xml
Open web.xml in notepad & modify default-listings-false to true
Open server.xml & change port number 8080 to any other (8081) if any
application access the same port Open context.xml change reloadable attribute to
true on figurationprocedure varies according to the version
Step 8: Try to start Tomcat server by running the "startup" command in a command
Line window:

OUTPUT:

RESULT:
Thus the Tomcat server is installed and configured successfully
Ex.No:5.A INVOKING SERVLET FROM HTML FORMS

AIM:

To write a html program for invoking servlet using html.

ALGORITHM:

Step1: In html program, define the html, head and title tag.
Step2: Then the title is Student Information Form and close the title and head tag.
Step3: Define the body tag inside the body tag create form and table
simultaneously.
Step4: The table consists of following information Roll no, Student name,
Address, Phone no and total marks.
Step5: In the servlet program, import the summary package and create a
own servlet class extends with generic servlet.
Step6: In the service method defined to request and response.
Step7: Create the object and for print writer and get writer()value.
Step8: The enumeration object get the servlet request parameter.
Step9: Create objects for string method and it is displayed another object value
received get parameter of name received and displayed the value
received value.

Ex.No:5.B SESSION TRACKING

AIM:
To write a html program for invoking servlet using html.

ALGORITHM:

STEP 1: Remove a specific attribute You can delete the value associated with a specific key
by calling the public void remove Attribute(String name) function.
STEP 2:Delete your whole session. To delete an entire session, use the public void invalidate()
function.
STEP 3:Setting Session Timeout You may set the timeout for a session separately by calling
the public void set MaxInactiveInterval(int interval) function.
STEP 4:Log the user out On servers that support servlets 2.4, you may use the logout method
to log the client out of the Web server and invalidate all of the users’ sessions.
STEP 4:web.xml Configuration If you’re using Tomcat, you may set the session timeout in the
web.xml file, in addition to the ways listed above.

Ex.No:6.B DISPLAYING STUDENT MARKLIST USING JSP

AIM:
To create a three-tier application for displaying student mark list using JSP and database.

ALGORITHM:
1. Design the HTML page (stud.html) with the following
a) Create a form to get the input (Register Number) from the user.
b) Set the URL of the server (marklist.jsp) as the value of the action attribute.
c) Use submit button to invoke the server and send the form data to the server.
2. Create the JSP file with the following
a) Read the parameter value (Register Number) from the form by using the
method getParameter().
b) Server retrieves the details from the database table with respect to the form input.
c) Server displays the mark list to the client as the response.
PROGRAM:
marklist.jsp:

<%@ page contentType="text/html" language="java" import="java.sql.*"%>

Ex.No:7. XML SCHEMA FOR STUDENT DETAILS

AIM:
To write a program for implementing student information using XML & XSL.

ALGORITHM:

Step1:The XML document reference to the XSL document.


Step2: The create the student information in the student tag and insert the same
information about the student.
Step3:Close all opened tags.
Step4:In XSL document create a html file include the student information in table format.
Step5:Close the necessary tags.

PROGRAM:
