Examples of org.apache.openejb.InvalidateReferenceException

org.apache.openejb.InvalidateReferenceException
This type is thrown when the EnterpriseBean throws a RuntimeException or system exception that results in the eviction of the bean instance. The InvalidateReferenceException's nested exception will be a RemoteException or possibly an ObjectNotFoundException. The Application Server must catch the InvalidateReferenceException and its nested exception rethrown by the bean proxy. After the exception is re-thrown by the bean proxy, the bean proxy must be invalidated so that all subsequent invocations by the client on that bean proxy throw a RemoteException. The proxy is made invalid. InvalidateReferenceException is non-system exception; it does NOT indicate a problem with the container itself. @see ApplicationException @see InvalidateReferenceException @see OpenEJBException @see SystemException
