2. Tomcat 4.1, 
3. Servlet program Name: FirstServlet.java 
4. Program saved into below directory:

         C:\Program Files\Apache Group\Tomcat 4.1\webapps\examples\WEB-INF\classes\

Follow Instruction below

Right click on your My Computer icon of desktop.

Go to -> Advanced Tab. -> Environmental variables

Click on that you will find all the system variables lies over there.

In User Variables section you can create environmental variables. Now click on new

1) Variable name: class path

value :<path till lib of installed java>e.g.(C:\Program Files\Java\jdk1.5.0\lib);.;<path till lib of tomcat> e.g.(C:\Program Files\Apache Software Foundation\Tomcat 6.0\lib);<path till jsp- api.jar>;<path till servlet-api.jar>e.g(C:\Program Files\Apache Software Foundation\Tomcat 6.0\lib\servlet-api.jar;C:\Program Files\Apache Software Foundation\Tomcat 6.0\lib\jsp- api.jar);.;

CLASSPATH
C:\Program Files\Java\jdk1.5.0_05\lib;C:\Program Files\Apache Group\Tomcat 4.1\common\lib;C:\Program Files\Apache Group\Tomcat 4.1\common\lib\servlet.jar;

2) Variable name: path

Value: <path till bin of installed java>;<path till bin of tomcat> click ok to create this variable.

PATH
C:\Program Files\Java\jdk1.5.0_05\bin;C:\Program Files\Apache Group\Tomcat 4.1\bin;

3) Variable name: CATALINA_HOME

 Value :< path till tomcat base> e.g.(C:\Program Files\Apache Software Foundation\Tomcat 6.0)

CATALINA_HOME
C:\Program Files\Apache Group\Tomcat 4.1;C:\Program Files\Java\jdk1.5.0_05;

4) Variable name: JAVA_HOME

 Value : <path till java base> e.g.(C:\Program Files\Java\jdk1.5.0)

JAVA_HOME 
C:\Program Files\Java\jdk1.5.0_05

javac FirstServlet.java
Start tomcat server,
Internet Explorer,.
http://localhost:8080/examples/servlet/FirstServlet

Your Output will display

Tomcat 1.5 or higher version

Compile the program and place .class file into

C:\Program Files\Apache Software Foundation\Tomcat 5.5\webapps\servlets- examples\WEB-INF\classes this Directory.

Make Change into web.xml file,

<servlet>
<servlet-name>Nameof Program</servlet-name> <servlet-class> Nameof Program </servlet-class> </servlet> <servlet-mapping>
<servlet-name> Nameof Program </servlet-name> <url-pattern>/servlet/ Nameof Program </url-pattern> </servlet-mapping> http://localhost:8080/servlets-examples/servlet/ Nameof Program

Your Output will display....Thank You.
