Let me give some more info here to explain what I am trying to do.
This suite of web-apps used to run in Jrun. It used jakarta commons-logging wrapping around Log4j. Log4j was not connected to JRun in the same way as it is connected to JBoss. In order to get logging to work, I had to create a special Log4j initialization servlet that was the first servlet loaded by the first web-app loaded.
Since JBoss (and standards) provide no way to assure which web app loads first that won't work. Commons-logging no longer finds log4j. Has anyone else used commons-logging in JBoss this way?
