Tomcat Error: Requested Resource is not Available.

Question

I'm working on a Struts project, which involves working w/ JSP pages, Tomcat and Java classes.
I keep receiving the following error whenever I click on a link on my main JSP page. My Servlet's name is StrutsGame, which is defined in web.xml
HTTP Status 404 - Servlet StrutsGame is not available
type Status report
message Servlet StrutsGame is not available
description The requested resource (Servlet StrutsGame is not available) is not available.
Apache Tomcat/5.5.20Note that I do not get this problem when I enter the main jsp, although this is under the same servlet name.
My main jsp page is called DisplayMainMenu.jsp, which contains links to GetAddInfo.jsp, GetDeleteInfo.jsp, GetEditName.jsp and DisplayGames.jsp.
I receive the problem discussed above when I click on GetAddInfo.jsp.
Here's how my web.xml looks like. Please help out!

make this sample web.xml as your reference:
<?xml version = '1.0' encoding = 'windows-1252'?>
