being totally new to EJB technology, I really want a book that is much easier to understand. So I wanted to read HF EJB book.
But can anyone tell me if that is a good choice of first book to read if I want to write SCBCD 5 for EJB3. Will I be confused about the whole thing if I read the old one. Or are somethings still the same, in both EJB2 and 3...
Or should I just go ahead and read Mastering EJB3, or Orielly book first.
please post opinions....those who are already aware of the differences between EJB2 and 3...

The whole concept is more or less the same, but way to make things has completely changed. It will do more harm than good to read an old book and go for scbcd5. If you decide to go for SCBCD, you'd better read an EJB3 book.
I think it's a good idea to go for SCBCD 5. I've been playing around with EJB 3 for a while and I must say it's less complicated than EJB 2.x. Unless you're dealing with a lot of legacy apps, then SCBCD 5 should be the one you should pursue. I also heard that there will be a lot upgrade exams coming up for Java EE 5, e.g. SCWCD (not yet), SCBCD (already there), SCDJWS (not yet), SCEA (beta). It's always good to keep your skills updated to the latest technologies. My 2 cents
For the book, mainly JPA, I can recommend Pro EJB 3 Java Persistence API by Apress. It's a quite easy to understand and it covers a lot of stuff.
SCJP 5.0, SCWCD 1.4, SCBCD 1.3, SCDJWS 1.4
I have found that the exam usually comes down to what is in the specification. When you read a certification study guide you read a distilled translation of the intent of the specification creators. You have to hope that the prep author sees the same level of importance as the spec authors and the exam creation team.
Yes study guides help alot and are much easier to understand than the spec.
But you should read most of the EJB #.#(what ever version the test is on) spec
A piece of advice: If you aspire for the HFEJB book, do have a look at the errata first!
I do not think the exam preparation books are good as an introduction to EJB .
I would instead recommend tutorials on the net, such as those that can be found at: <a href="http://www.netbeans.org/kb/index.html" target="_blank" rel="nofollow">http://www.netbeans.org/kb/index.html</a>
For more alternatives, use a search-engine of your choice!
If you want to prepare for the certification, I think reading the specs is inevitable - the exam preparation books I have seen all seems to lack detail to some extent.
Hi , I think its better go for SCBCD 5.O as , it has started gaining popularity, also people who are using java 5.0 they can use EJB 3.O get the same benefits of Spring & Hibernate. So in future SCBCD 5.O will be more popular, its better to go for 5.O About the books i think you can start with Mastering EJB(Latest edition) & then Oriely, at last go for Spec's
