How about some information on the environment you are trying to run in.
Java version
Tomcat version
Operating system
-- Can you get the Tomcat example JSP to run?
-- Have you looked at the servlet source that throws the error?

did you copy any sort of servlet.jar or server-api.jar from one directory to another? If so, undo that and try again.
