New App on Tomcat 5.0.19

I am converting an application containing JSP pages and servlets from Tomcat 3.3 to Tomcat 5.0.19. I have moved my web application to be under the /webapps directory and the initial HTML page is found and comes up correctly. But when the first servlet is invoked, I get an error from Tomcat: HTTP Status 404: /insidezos20/servlet/checkuser Description : The requested resource (/insidezos20/servlet/checkuser) is not available. I think there may be some type of configuration I need to do in [login to view URL] or web.xml. I have tried a few things and only end up with more errors. I would appreciate some help. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) All deliverables will be considered "work made for hire" under U.S. Copyright law.
