final class problem
Hi,
I have a web app which was working fine. I made a lot of changes, and it works fine on my
machine at home. But when I try to install it on my server, using the tomcat manager init
command, I get this error. If I knew which class it was trying to instanciate, I might be
able to fix it, but I'm basically hoping that someone has seen this before and knows what
the problem is. None of the classes I wrote are marked 'final'.
This dump was copied from the app log.
Thanks in advance for any clues:
