RE: setting up multiple log4j configurations for multiple WAR pac kage s?

[Jacob Kjome <ho...@visi.com>]

Does JRun not load from the WebappClassLoader first?  Tomcat does this, and 
I believe the servlet spec defines this behavior (but don't quote me on 
that).  Sounds like the same thing JBoss does by default.  The way Tomcat 
works makes things much easier to work with since libraries in the server 
won't mess up your webapp which has its own versions locally with the 
webapp.  I'll be JRun can be configured to load from the WebappClassLoader 
first.  Might want to look at see.  Otherwise, you can do configuration 
yourself and use a repository selector from the log4j sandbox.  Search the 
archives and the Wiki for more info on using repository selectors in 
application servers.
