Howdy, Your problem is not log4j, it's commons-logging, which is nearly always the culprit. The issue arises if log4j is in a classloader below commons-logging, so commons-logging doesn't know log4j is there. You're configuring log4j OK, and if you used a log4j Logger rather than a commons-logging Log, you'd see expected behavior. But you're using a commons-logging Log, which uses the commons-logging configuration, which is tied to your server and outputs to the console.
