web.xml is the 'deployment descriptor'. It's a part of the specification for j2ee webapps. It typically contains details for configuring your application, resource mappings etc.
create a folder by name printapp in webapps of tomcat
create a folder by name 'WEB-INF' isnide printapp
create a folder by name classes inside WEB-INF
create a file by name web.xml and copy the following into it.
<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
version="2.4">
<servlet>
<servlet-name>Simple</servlet-name>
<servlet-class>simple.SimplePrint</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>Simple</servlet-name>
<url-pattern>/simple</url-pattern>
</servlet-mapping>
</webapp>
put the web.xml into WEB-INF.
Compile your servlet (ensure you have a package statement on top in the servlet source - sthing like - package simple;) into classes folder of web-inf
+printapp
- WEB-INF
- web.xml
+ classes
simple.SimplePrint (with the package folder)
restart tomcat and access as http://localhost:8080/printapp/simple
All the best. Search these forums there are infinite no. of examples
