client consideration in SCJA exam

[Larry Li]

Hello:
I am taking the part II of SCJA. I have a question on designing the client tier. It looks like from the requirement that I need to support both web client (i.e. JSP) and stand alone client (GUI based). I have done the class diagram and I don't really have any class that deals with client (is this right?). But when I move to the component diagram, I am not sure how to handle different clients. I have one starting from JSP to servlet to EJB and backend. Am I supposed to have another one that supports stand alone GUI client (basically EJB client)? I would appreciate any insight from all of you who have passed.
Thank you very much in advance.
