hello
we're running tomcat 4.0.3 (I know it's old, but I can't change it).
following problem occurs:
when invoking the Servlet from a client i get the error messages below. the
restart seems to be ok though. also it is interesting that the error
messages
depend wheter it the servlet is placed in a package or not.
first there are the messages from palcing it directly in the
.../hiApplServerDev/WEB-INF/classes directly. after the ====-line, you will
find the exceptions thrown if it is placed in classes/highMediator-directory
and it is part of the highMediator-package.
i have romved a big part of the stack traces, but will post it if needed.
also
pls tell me if code is helping you.
I haven't been working on it for a while, but as i remember i have used it
the
same way before without any problems. I've spent the last two days with the
problem, but can't get anywhere....
I am grateful for any hints in which direction to go from here.
THANKS
pete
