Just come back from the exam center.
I would like to share some of my experiences about SCBCD.
I have 8 DND questions. 3 of them are EJB-QL, 2 of them are Transactions, 1 of them is Stateful Session Bean life cycle, 1 of them is Stateless Session Bean life cycle, and 1 of them is Entity Bean life cycle.
I got 3 answers wrongly. 2 in EJB-QL, and 1 in Transaction.
I feel EJB-QL are quite difficult, as I almost cannot find a suitable answer (from the DND options) that I feel it is correct. You must fully understand each clause of EJB-QL, and know which clause is for what.
For example, you should
know abstract scheme is used define the table that used in EJB-QL FROM clause.
Transaction questions are straight forward, except one question that ask for the call sequence of the Stateful Session Bean that implements SessionSynchronization interface. You must know the caller sequences, and how the transaction status in each of the sequence.
Hope this help.
