Edit the log4j.xml file in the conf folder of your server type. Add a new appender and category infos.
That's exactly what I'm trying to avoid. I already have the log4j.xml files with the correct info for each of my web apps. I want JBoss to use them instead of the main log4j.xml file.
This is how it works with WebLogic, and I'm trying to make it work the same here.
I have the same problem with the log4j.properties files. The isolation (by the way default in JBoss 4.0) does not do the job...
Did it work for you?
