Step 1:
First think we have to download Apache Tomcat...
You can go to home site of apache or Click here

Step 2:
Extract the downloaded zip file into C:

 

 Step 3:
create new folder in webapps folder... consider our folder name is "test"

Step 4:
create another folder within "test" folder.. set new folder name as "WEB-INF"

Step 5:
create "classes" folder within "WEB-INF" folder..

Step 6:
create web.xml file within WEB_INF folder.
and copy and paste following code into web.xml file

web.xml


<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<web-app>
<servlet>
<servlet-name>Hello</servlet-name>
<servlet-class>Hello</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>Hello</servlet-name>
<url-pattern>/Hello</url-pattern>
</servlet-mapping>
</web-app>


here Hello is a servlet class name..
each an every time we have to put entry in web.xml file for every new servlet class..

Step 7:
now we have to start the server..
