Thanks mainly to Entuware, James Sutherland, and all the success stories from which I got the guidance for preparation.
It's good feeling... that I'm a SCBCD for EJB 3.0.
Frankly speaking the exam was tough... it's all scenario based. No straight question. While solving mock exams I used to solve it within say 1 hr. but here it took 2 Hrs 10 minutes to complete the test.
Well here is how I prepared for it...
It's for those who already have knowledge of EJB 2.0 or 2.1
Read first..... Enterprise Java Beans by Oreilly publications. Too good book.
Then read sun's specifications.. Yes I mean it.. How much time it would take.. total you'll have to read around 1000 pages but its worth.
I tell you.... you will get the same code with some words shuffled here and there.. from the specs in your exam. Read it carefully. Try to understand.
But don't read EJB QL from specs. I don't like the way it's explained. Instead go for Oreilly's book.
Then again make one repetition of Enterprise Java Beans by Oreilly... publications. And finally one more times the specs.
Then start solving Enthuware mocks.... You'll score well in the mock exams I'm sure..
but the Enthuware mock doesn't have variety of questions for JPA.. It's all straight forward questions in Enthuware for JPA. (Directly taken from specs).
What I've experienced in the SCBCD is you'll get some design based questions on JPA. They will ask you to design certain things.. and what's going to be your approach, or what you'll do in this etc.
Since JPA is new.. I would recommend Enterprise Java Beans by Oreilly... publications. You'll get code samples, descriptors for each annotations.. that's what you need.
And JNDI ENC, Transactions, Exceptions, it's really good in Specs as well as in the same book.
See on the day of exam just make a revision of those code samples from Enterprise Java Beans by Oreilly... publications.
The mock exams from enthuware are really good. They will make you think in specified time limit.
If you do this much you are done..
Guaranteed to get the certification.
And for those who don't know EJBs and want to start preparing for it.. I would recommend read Head First EJB (The best book on EJB)
Once again I thank all of you for your posts... those really guided me... for my preparations.
