Examples of org.apache.openejb.SystemException

org.apache.openejb.SystemException
This exception is thrown when the container has encountered an unresolvable system exception that make this Container unable to process requests. A breakdown in communication with one of the primary services or a RuntimeException thrown within the container (not by a bean) is are good examples. The org.apache.openejb.SystemException represents a serious problem with the Container or request. NOTE: This exception bears no resemblence to the unchecked exceptions and errors that an enterprise bean instance may throw during the execution of a session or entity bean business method, a message-driven bean onMessage method, or a container callback method (e.g. ejbLoad). See InvalidateReferenceException for this. @see ApplicationException @see InvalidateReferenceException @see OpenEJBException @see SystemException
