Java EE (Java Enterprise Edition) General Discussion

Currently I'm working on a inventory management system in which the users are validated and redirected to the main page. Main page is a jsp and I'm using Jboss 4.0 as the server and myeclipse IDE. But when the request is dispatched to the jsp, I get a Missing Resource Exception. and it says "can't find resource bundle for org.apache.....jasper.resources.messages ". I tried to access the same jsp in a test project to find if there is an error in the jsp. Then the jsp was correctly displayed. I have also added the required libs(jasper-reports.jar,jasper.jar). And in my jsp neither of these jars are used. Please give me a guide..
