Hi Wolf-Dieter,
I am a real beginner with JBoss 7, what do you mean with "you have to add the classes as module in module
/org/apache/log4j/chainsaw/main"?
/org/apache/log4j/chainsaw/main is in the logging JAR log4j.jar.
How your module/ directory looks like? I have uploaded an example- Application, it would be very kind if you could have a look at it.
Thanks a lot for your help!!
