The problem with the ServletContextListener approach is that it takes over
the log4j for all apps.
For instance, I have two web apps running in geronimo. They share a common
code base. I need each one to manage their own logging. Right now using
the Listener approach, the following occurs.
WebApp 1 starts up and begins logging com.my.package
Everything looks good so far.
WebApp2 starts up and begins logging com.my.package. Now WebApp 1 is no
longer writing out to the log files and WebApp2's logs contains logging
information from WebApp1 and WebApp2.
By the way in both cases the geronimo.log file is affected as well.
