Subject: Re: [EJB-INT] which of these should be an entity bean?
Yes and no. :) For the methods of TeacherLite to be available in the
Entity Bean, you would need to declare the methods either in the Teacher
interface itself or in a TeacherLiteIfc interface that Teacher extends;
in either case the method signatures in the interface would have to
declare "throws RemoteException" but the methods in the TeacherLite
class itself would not be required to do so. And this actually makes
sense, because when TeacherLite is used by itself, it's not remote and
its methods do not throw RemoteException; when the methods are accessed
via the Entity Bean, it IS remote, and the remote interface method
signatures DO declare "throw RemoteException".
Make sense?
