Explaination : Local Client might have a remote component object, in that case it can see all the above methods and infact use it. In the question only the client is local not the component.
I think you are right. Although a remote interface can give out only remote component interface references and local home can give out only local component interfaces, I think local client can access a remote home without narrowing. So, I agree with you that all the options in the given question are correct. Looking at the answer to this question, I can tell you that the question should rather look like the following - "Which session bean local component interface method(s) can be called successfully, by a local client?" But not to worry, as far as I know the questions in the real exam are stated very clearly. So, you are not likely to face this type of problem in the real exam. Anyway, If you dont mind me asking, when is your exam due? Regards Suman

Hi Mini, I know you are studying hard to prepare yourself for the exam. Knowing that you have only a couple of days left to sit for the exam, I would like to give you just one more piece of information regarding the SCBCD exam. I think the objective of the exam that you might want to give a little more attention to is that of EJB-QL. The HFEJB book does not really cover it all when it comes to EJB-QL. The reason I am saying this is most people think ELB-QL is very easy. They under-estimate the importance of EJB-QL and eventually get a low score in it. I hope you wont make the same mistake. Good luck Suman
the session bean can call remove(Object key) on the EJBHome, but the container will throw RemoteException. remove(Object key) method is for only entity bean. You have to know that the question is "called Successfully". as u said, a & b& c&d(never seen)methods are called. but for a, c is ok. but for b, there is no method named getHandle() in the EJBLocalObject interface. so it cause to throw an exception.
that's what i think that answer a,c is correct. [ June 22, 2004: Message edited by: youngwoo seo ]
