I am pretty sure that Tomcat and Jboss will run independantly in separate VM instances, and hence definately separate class loaders. This implies there will be two indepedant instances of Log4j running, and they will need to log to separate files.

What is very useful is setting the log4j debugging on (-Dlog4j.debug=on). And if you search for "using" you might find that log4j is using multiple configuration files. Currently I'm trying to figure out if that is the case with my problem.
