Any exception that specializes EJBException is a system exception.
Any system exception destroys the bean.
Any other exception is an application exception (apart from CreateException
& FinderException too) and they wont destroy the bean instance.
The critical difference is in the transaction support.
Application exceptions do NOT support automatic rollbacks, one has to use
EJBContext.setRollBackOnly() method to trigger a roll back.

Jeff,
Please review section 12.3.1 table 8 of the EJB 1.1 which gives very
explicity desriptions of what impact throwing a SystemException
(RemoteException or EJBException), an Application Exception or a
RuntimeException.
I dont want to make this confusing so Id suggest making a xerox of the table
and referring to it.
