Hi Scott,
Thanks for your detailed reply. The chapter is very informative and it's
great to get assistance from the guy who wrote it!
When I loaded illegal.jsp last night the page redirected as it should and
showed the exception inheritance tree. When I ran the page this morning,
however, it doesn't redirect. It simply reports the error at line 6: Attempt
to divide by zero. I can't think of any changes I've made to the server or
environment. I've appended the error message below my signature.
Regards,
Marc Garrett
