SCEA part 1: EJB 2 and EJB 3 ?

hi,
reading the objectives of the SCEA part 1, i find that EJB 2 and EJB 3 seem to be part of the exam.
I find it strange that both versions are part of the exam, although it does make a bit sense since EJB 2 is still in use in a lot of projects.

How many questions about EJB 2 and how many questions about EJB 3 can we expect in the exam ?
50%-50% ?

I can't remember, but the question will be very high-level. You should focus on EJB 3 and JPA.

It's really EJB3.

But you should know the benefits EJB3 has over EJB2.x. Plus, an architect does need some basic EJB2 knowledge. I mean, if you've already got a working EJB2 environment, you should know that there's really no need to change it.

Focus on the changes between EJB2 and EJB3, which is pretty much the first chapter of every EJB3 book on the market. But you certainly don't need any deep knowledge of EJB2.

well,
thats good it's basically only EJB 3.
It would be a pain to have to remember again all the details of both versions of the EJB.

So i guess i will focus on EJB 3, with very little study (or none at all) on EJB 2.

No, no need to study details. The questions in part 1 are very high-level or scenario-based.

I cannot really remember but it requires very little technical knowledge, you should focus more on EJB 3 architecture and design (only high level).

I just noticed that you already have SCBCD 1.3 and 5.0. In that case don't need to study EJB (in preparation for SCEA part 1) anymore it will be only waste of your time.

There won't be too many direct questions on EJB 2.x, but you need to know EJB 2.x enough to answer questions like, "How does EJB 3 improve so-and-so aspect when compared to EJB 2.x?" . But you can expect the exam to basically focus on EJB 3.

Ken Shastri,

but in the exam I may find a question about interfaces and methods used in EJB prior to EJB3, right?

And about persistence, I may find a question about Entity Beans I can't answer if I only know JPA, right? I mean, will I need to study about Entity Beans prior to EJB3?

Thank you very much. Bye

Antonio

You should not, that is too complicated for SCEA 5 part 1.

Thank you very much for your reply.

About the other question, will I have any question about persistence (Entity Beans) prior to JPA?

Thank you very much. Bye

You can read the Exam Objectives. I cannot remember.
