Hi folks,

I'd like more control over the class loader so that I can  specify classes to ignore if they are provided outside of my web  application. Is there a way to tell my application's class loader to NOT delegate to the parent for a named list of packages or jars?

For example, if I don't package Hibernate in my WAR and some class attempts to load org.hibernate.SessionFactory, I want a ClassNotFoundException (or similar). I do not want it loading the Hibernate classes from the jar's currently in common/lib.

Constraints are I cannot delete or modify any jars in /common/lib, so I need a different way (maybe jboss-web.xml or jboss-classloader.xml or something) to stop it happening. Is it possible?
