Tomcat JSP issues

[Nicole.Winfrey]

I'm deploying a war file to Tomcat 5.5. The war file contains
precompiled JSPs.
Noted that in the WEB-INF/compiledjsp folder, there is a
generated_web.xml (generated by jspc).
When I go to the JSP after the war file is deployed, I got the
following error, which I never got it before on Tomcat 4.1.24. It used
to work on Tomcat 4.1.24.
Any clues as to the possible causes for this error?? Is it a
configuration issue on Tomcat 5.5 that I haven't set?
