The default webapp usually has /usr/WebSphere/AppServer/servlets
added to its classpath. You can see the classpaths for a webapp
through the admin console.
If you are trying to access ur servlets thru a different webapp,
then check the classpath for it in the admin console.
For unregistered servlets :
http://ip/webapp/servlet/package.servlet For registered servlets :
http://ip/webapp/servlet-alias
