Hi! All, Suppose we have 2 CMP entity beans like in Branch & Accounts relationship. Where do we set the navigable property? a) The Navigable property on the Branch side of the relationship. b) The Navigable property on the Account side of the relationship. Where shud we use 1..* or 0..* multiplicity? In EJB 2.0 specs there is no mention of 1..*. What I have understood is that 1..* makes the record mandatory and not optional? Plz explain.

The answer should be "B" if there is only 1 correct answer. Normally you want get the Branch info for where the Account belong to. So we can navigate from account to branch. You are correct about the multiplicity. But related information is not from EJB2.0, it is from EJB Association, which is an IBM extension for EJB1.1.
