Need an advice for preparation of SCBCD exam regarding book selection. As far as I found , just two books are highly recommended :
1.Enterprise Java Bean 3.0 O'Reilly
2.EJB 3 in action
I have gone through their first pages on amazon and they seem quite difficult for a person who is new to EJB like me.
Just wondering is it worth to buy HEAD FIRST EJB 2.0 to understand the EJB world and clear the basics , and then jump on these books?
How different is EJB 3 is from EJB 2?
But just curious why not read EJB 2 before exam :-)
I think that it will confuse you more than it can help. The way beans are used has changed. Entity beans have also completely changed. After studying EJB2, you'll have to rethink a few things, learn new annotations, learn JPA... Unless you have some time and some strong interest in EJB2.x, if I were you I'd leave them for later.
I would prefer to say that use HF Ejb 2 if you are new to ejb, not all the chapters but first few, introduction and sesion bean. It won't be bad idea. HF is good for introduction as it share developers concerns (it imagine what would be new bee's doubt). Quick few would be helpful to solve you doubts.
Migration from ejb 2 to 3 is one of the topics , you would be able to understand the things need to take care easily.
Another thing, ejb 3 in action, says this is big improvement compare to ejb 2 at lot of places, you could understand (imagine) the things.
Jndi lookup is still relevent (Imp) with ejb 3, you can understand it in better way with HF.
My view are for people who are new to ejb and have few extra days to prepare for exam.
No match to HF to understand the basics of tech for new comer.

Yes I agree with what you said. HF EJB 2 is a very good book and everyone should read a few chapters from it. And I guess new HF book would be in market after 6 months.
