This is true for the most part.  Once you manage to figure out how it works, it really isn't that difficult to manage.  The difficulty becomes when you use common classes that span multiple ear files that are deployed to the same instance.  If you are actively developing and need to redeploy the common classes, then you have to rebuild each ear that is deployed - the loaders aren't isolated to the extent that each can have a different version of the same class.  It (JBoss) craps-out with a meaningless error message when this occurs.

As far as I know, the classloader architecture is pretty much madated by
the J2EE spec, and there is not much that can be done with it.

This currently gives me serious headaches with JBoss. Oh yes, 
please make a 
better classloading architecture compared to JBoss!
