I hope it looks like UML for CMR.
This is really a UML question (dont use that as an excuse to mark it to some UML beginner forum) but I am sure its very relevant to EJB.
I am not too good with UML but might get around to learning it after Head first K&B release their UML book.

If in FirstBean I dont have the CMR field getOtherBeanRef() [otherBeanRef]
will the arrow become?
<---------------------------
or will it become?
--------------------------->


I think it will become <--------------------------- because there will be no way to reach OtherBean from FirstBean

Waiting for a reply.
