So what you actually want is to put in your own log4j.properties
and have it logged out to your logfile?
Yeah it's a pain to configure in WAS. I gave it up at the time.
In the .pdf document there is something about selection of classloading strategy, where to place the .jar files in either WEB-INF/lib og as utility jars in and defined in the MANIFEST.MF that is in your .ear file so logging also works from EJB's if you use this.
I don't have the .pdf anymore as I have switched to a new computer and haven't been on that project for 6+ months.
Just go to www.ibm.com and search for "log4j was" and you'll find it.
