Ricky,
That's interesting! I would like to try the "error page functionality"
that you talked about. If you can give me some hints about how to use it,
that would be greatly appreciated. I don't understand how you can pass
the ServletException all the way up to the Error JSP without changing the
existing struts code. (May be I should get the latest code!). I guess
this will make more sense when I learn about the error page functionality.
Thanks for your time.
