Download ejb_codecamp_all.zip from this site. Has very good information / details / notes (presentation sort of ) on EJB stuff. Has pdf for exercises. Explains in terms of use cases, class diagrams, value objects. TOO GOOD.
This site requires a sort of registration in terms of email id etc(does not validate. any id / address will do). But this should not discourage one from downloading the stuff.
