Description:
JBoss is infamous for its UnifiedClassLoader, which doesn't seem to behave like
a typical J2EE classloader.  I've tried numerous JBoss configurations, but none
of them seem to do everything that I need.

I've checked their bug reports and they seem to think it's a problem with "the
Apache guys" caching classes.

I am deploying session beans in an  ear file, and using the java:EJB provider to
invoke them as web services.  This works great on a fresh deployment with a
newly started server, but when I redeploy, I frequently have problems with
NullPointerExceptions.

Does anyone have a thought or suggestion about this problem?  I would be willing
to help out with testing in JBoss.

Thanks for any help or info that you can provide!
