Hi, all,
I'm studying the "SCEA for J2EE Techonology Study Guide".
When I study the example case on chapter 8, some of classes in the sequence diagram cannot be found in the class diagram, such as xxxxJSP, xxxxVO. Is this method correct and acceptable in real SECA exam? May any passed SCEA experts share your opinions?
Thanks in advance!
Eric

Hi Eric,
I once read that book. I think the class diagram is used to present the domain business classes. Since XXXJSP and XXXVO is related to concrete technology (JSP) and pattern (Value Object), they need not to be shown in class diagram.
