public class SystemException
extends javax.ejb.EJBException
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.

The SystemException class is closely tied to the MessageCatalog. An SystemException contains a log and user message that is constructed using the MessageCatalog. In fact, each SystemException derivative should have at least one user and log catalog message.

In the case of an EJB, the following guidelines should be followed:

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.

A bean provider is responsible for using the standard EJB system exceptions (EJBException and NoSuchEntityException) where appropriate.

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. In the case of a bean method that calls another bean method, all RemoteExceptions should simply be propagated from the bean method.

If an EJB method throws a SystemException, any existing transaction will be rolled back by the Container and the bean's state will be set to "does not exists".
