public class SystemException

extends java.lang.RuntimeException

implements MessageCatalogException

The SystemException class is used to signal system-level exceptions to a caller. It is the base system exception class. A system-level exception is a severe exception that prevents a thread of execution from proceeding in a normal manner.

If an enterprise bean method encounters a system-level exception or error that does not allow the method to successfully complete, the method should throw a suitable system exception compatible with the method's throw clause:

• If the bean method encounters a RuntimeException or error, it should simply propagate the error from the bean method to the Container.
• If the bean method encounters a checked exception that the bean cannot recover from, the bean method should throw a SystemException or derivative that wraps the original exception.
• Any other fatal error should be reported using a SystemException or EJBException.

Since the practice of throwing a RemoteException has been deprecated in the EJB 1.1 specification, all such occurrences must be replaced with an instance of SystemException.

Finally, a bean provider is responsible for using the standard EJB system exceptions (EJBException and javax.ejb.NoSuchEntityException) where appropriate.
