throw RemoteException to the client?

[Himai Minh]

According to the JSR 318,
1. RemoteException is deprecated since EJB 1.1.
2. web service client of a bean gets RemoteException when a bean throws a system exception.
3. a business method of a session bean and the onMessage method of a MDB do not throw RemoteException.

I am wondering about 2. If RemoteException is not used anymore, why the web service client gets RemoteException ? For backward compatibility? Or, with EJB 3.1, all the beans throw EJBException that wraps any system exception ?

Enthuware mock exam points out that a system exception is wrapped as a RemoteException and being thrown to the remote client.
I am waiting for their reply and ask this question on this forum.

For backward compatibility?

Yes, that is the only reason!
