hi yoav, I've been showing up here some months ago, and now you're still on your job answering the many answers here. I'm impressed...
I'll take a look into the Log4J.MDC - don't you think it would make sense to provide guidelines on how to log debugmessages and exceptions in servlet/jsp-apps (like the App Dev. Guide of Craig)? or is there already something at the log4j site you know of? thx alot Johannes
