Subject Re: Log4J doesn't work at all

That system property stuff only applies to commons-logging, not Log4j.  Look 
more closely at the instructions [1].

BTW, are you using commons-logging-api.jar?  If so, that's the problem.  You 
need commons-logging.jar.  See the commons-logging release notes [2].
