File not found exception ...

Hi friends,

I deployed a servlet called SimpleServlet into weblogic server but when i tried to call it from html page it gives file not found (error 404)error.Same program is getting executed when i use tomcat server.What may be the problem.

Hierarchy is as follows

Simple(.java file)/WEB-INF(.xml files)/classes(.class files)

The program is successfully getting deployed and deployment descriptors are also created.

plz help me out.
