The root of the confution is that in EJBs the bean implementation doesn't
directly implement the remote interface. If this were so, your bean
wouldn't have compiled.
In your remote interface, you said that the 'getMessage' method threw only
RemoteException. However, your bean's implementation of 'getMessage' is
declared as throwing MessageException. Because of the way the interface is
defined, the client side stubs get an exception (through the RMI
call) that they don't expect. This causes the UndeclaredThrowableException
you've been seeing.
