public class ApplicationException
extends OpenEJBException

This exception is thrown when a normal EnterpriseBean exception is thrown. It acts as a carrier or wrapper for the actual application exception. The ApplicationException's nested exception will be either an EJB spec defined ApplicationException ( or a custom exception defined by the bean developer) or a RemoteException. The org.apache.openejb.ApplicationException must be caught and its nested exception rethrown by the bean proxy to the client. The org.apache.openejb.ApplicationException is non-system exception; it does NOT indicate a problem with the contaienr itself.
