EX.NO :4 INSTALLING OF APACHE TOMCAT WEB SEVER DATE:
AIM:
INSTALLING OF APACHE 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"
page. Step 2: Click "32-bit Windows zip" link under "Binary Distributions" section.
Youwill 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 acommand
line 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 correctlyThis environment
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 figuration
procedure varies according to the version

DATE:
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. PROGRAM:

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

EX.NO : 6 B FOR DISPLAYING STUDENT MARKLIST.ASSUME THAT STUDENT
INFORMATION IS AVAILABLE IN A DATABASE WHICH HAS BEEN STORED IN A
DATABASE SERVER DATE:
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.
marklist.jsp:

EX.NO : 7 PROGRAMS USING XML-SCHEMA-XSLT/XSL DATE:
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:
//student.xml <?xml version="1.0"?> <?xml-stylesheet type="text/css"
href="student.css"?> <!DOCTYPE student SYSTEM "student.dtd"> <students>
