@Deprecated public class SystemException
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:
RuntimeException
or
error, it should simply propagate the error from the bean method to the Container.
SystemException
or
derivative that wraps the original exception.
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 RemoteException
s 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".

public SystemException()
SystemException
with no associated message.
public SystemException(SystemException topException, SystemException bottomException)
SystemException
from two source SystemException
s
by concatinating the screen and log messages of the two source SystemException
s.
The messages of the first SystemException
will preceed those of the second in the
constructed SystemException
. Furthermore, the new SystemException
will have the embedded exception of the first SystemException
associated with it.
