Hi!
After working with JBoss AOP successfully (I'm using standalone mode with loadtime
instrumentation) I tried to instrument a web application running inside a Tomcat
container.
This worked well for a very simple webapp but now, with a big and complex app, I'm in
trouble.
Whatever class I'm trying to instrument, no matter if it exists or not, I get the
following log output when Tomcat starts:
[ERROR] Error converting class .. Do verbose mode if you want full stack trace.
@org.jboss.aop.util.logging.AOPLogger.error
How do I "do verbose mode"? I'm using log4j.
Problems get more concrete when I try to instrument a class which actually exists in the
project:

I don't have a clue what to do with this and would be really happy to get some hints.
