j2sdkee1.3 bank application example

I have an error message sa follows:
Server Error
Your request cannot be completed. The server got the following error:
org.apache.jasper.JasperException
when I attempt to access AccountList, TransferFunds, or ATM once logged onto the application as 200/j2ee. The java application client works ok as does the logging on and logging out of the web app.
What could I check?
Has anyone seen this before?
Cheers
Sam
