Classloading Problem

Hi

I'm looking for a debugging aid for the following problem I'm struggle with
for some time. I'm using resin 2.1.6 with JDK 1.4.2_05.
The problem is I got the following error messages and I couldn't find the
wrong .jar .jsp .class file.  I used the JVM option -verbose:class
but it doesn't say any error message. The message is show several times at
startup and each time the class-update-interval is reached.
May be some of you has a good idea on how to catch this one.

Cheers
Karl-Heinz
