Log4j is not logging after JBoss start finish

[Leonardo Oliveira]

I have a problem with Log4j log. The JBoss is not logging after the start.
Server log is not empty. It contains all valid logging info up to the
point where JBoss finishes loading. The last entry is:

The Log4j service was started (I can see the message in boot.log) and my log4j.xml is:

Someone can help me?

Thank you,

Hi Leonardo,

do you supply your own log4j jar with the web application you're deploying? If so, this might be the reason for JBoss no longer logging. I've got the same problem where I use a 3rd party API that subclasses the log4j LoggerFactory, and this seems to interfere with JBoss' version of log4j. The effect is the same as you describe, no more logging. So, if you can rip out the log4j from your web app, try that ... if not (like in my case), I don't know ... if you come across a solution, please post it, I'd be interested in it as well!
