Can someone please point me towards some documentation which describes the advantage of the UnifiedClassLoader model over the tree-based class loading model? We purchased the JBoss documentation and all it says in the administrators guide is that “JBoss 3.x employs a new class loading architechture that facilitates sharing of classes across deployment units”. It also mentions that prior to this architecture, MBeans were not hot-deployable.   Is this basically saying that it allows you to hot-deploy a component without having to re-deploy those components which depend on it and its classes?   Any help here would be appreciated.   Thanks, Rob
