I do mean the class diagram. Cade shows 3 statesless session beans, but the rest are presumably POJOs eg Product, ShoppingCart, ReturnRequest etc. Some of these should be depicted in my opinion as EntityBeans eg Product (but not ShoppingCart - why isn't this shown as a Stateful Session Bean?).
What's your opinion? And why does Cade take this approach to doing his diagram. I'm somewhat confused about to what degree we should show a J2EE technology solution and have stereotypes indicting <<SessionBean>>, <<Filter>> etc in our class diagrams.
Any thoughts would be much appreciated.
