SCEA 5 and EJB

Merry XMas to you all !

Today I would like to ask a very simple Question. However I expect to have a very detailed answer if possible.
Here it goes(the question):

Do I need to know anything about EJB 2 (or any version prior to 3.0) Or is the exam part about EJB entirely about EJB 3.0 ?

If I do need to know something about prior versions of EJB please let know.

Best Regards,

J�se

Hi,

Based on my exposure, I only see the need for knowing EJB 3.0. The key difference is the JPA portion. "EJB3 In Action" is a good book for your Part1, Part2 and Part3 preparation with respect to EJB portion.

Hope the above helps.

Good Luck!

Cheers!!

No need of EJB2.0 knowledge, you can directly start from EJB3.0 ..yes EJB 3.0 in Action by Debu panda,Reza rehman is a good book to start with

Hi There !

That's a relief you know, However I already have knowledge on EJB 2.0, so there's no problem. But now I should focus on the new spec alone, to take the best profit out of the time I dedicate to this part.

However, I do have an important Question to ask:

Does EJB 3.0 still includes the methodology to handle Transactions ?

-- I mean the process where you would mark attributes in the deployment descriptor for Transactions (Required, RequiresNew, Mandatory, Supports, etc )

If the EJB 3.0 spec does not have that anymore, Has it included something new in the spec to replace Transaction functionality?

Nice work you guys, always good to have answers from you,

Good Luck, and I expect to read from you soon,

Sincerely,

Jose

Hi,

Transaction is still supported. You can either do it in the Deployment Descriptor for your Entities or use Annotations to do that.

Thank you!

Cheers!!

I did not mention EJB version anywhere in my assignment. I remember few others did the same. I think you can safely assume EJB3.0 and if you have to dive into version specific details you are probably overdoing it.
