Java EE (Java Enterprise Edition) General Discussion

hey guys,

I have a problem here. I used the cewolf tag library to display graphs/charts etc in my jsp page. It works perfectly in Tomcat. But when i execute the same using Jboss 4.0, i get the following exceptions -

14:11:45,225 ERROR [Engine] StandardWrapperValve[jsp]: Servlet.service() for servlet jsp threw exception
org.apache.jasper.JasperException: Unable to compile class for JSP
