Since class diagram should depict the static design of the system, however, in Cade's book example (Figure 8-6), it shows a class ShoppingCart which should not be one of the static design class, am I right?
Peter, The Shopping Cart is mentioned in the use cases, so I think Cade is correct to show it. However, I don't think he should show session beans. This is mixing up 'conceptual' and 'specification' views of a class diagram. However, since Cade was involved in setting up the SCEA exams, It looks like Class diagrams are open to interpretation.
