EJB implementation class loading with removed dependencies with ability to replace EJB implementation class without full redeployment

摘要

A system and method for EJB classloading. By changing the EJB classloading scheme so that the EJB impl class is loaded in a child ClassLoader, the system allows the old EJB impl class to be replaced with a new one without disturbing the rest of the deployment. The key to doing this is to remove all direct references to the EJB impl class from classes loaded in the parent ClassLoaders. Removing this dependency allows the old EJB impl class to be replaced at any time with a new impl class.
