SCBCD preparation problems...

Hi, I'm LITTLE confused.
I've been study from the manning "EJB in Action", book, at first, and that was starting point of my introduction with EJB.
However, in the previous preparation for SUN's certifications I found very useful the collection of "Head First" literature. Now I have start to study "Head First EJB". And, at very beginning, I found some miss-matches between these two books ( something like since "Head First EJB", has been written, some modifications are made in the ejb spec.
For Example, i 'HFE' is denoted that Session bean class MUST implements SessionBean interface, where in ejb specs. I found it's quite optional (in EJB in Action, it's not even mentioned).
Second, in HFE is stressed that also that Session bean class MUST provide TWO additional interfaces, where one containing business method, MUST extends EJBObject interface, and the other one used for making instance of first, MUST extends EJBHome or EJBLocalHome interfaces, where bot interfaces MUST throws RemoteExceptions?
Since NONE of this is mentioned in EJB in Action, who should I listening to, and what should I do (who has right)???
I'm completely stucked-up, until I resolve this mystery. Please, someone answer to me soon.
Thanks!

Bingo. Don't use it unless you want to know about EJB2.x

Which exam are you planning for? 2.x or 3.0? If it's 3.0, then it's good that you recognized the mismatch early, and you should have the in action book in your hand and not the hfejb.

hfejb3.0 is not yet in the market. and it won't be coming either.. (so soon?)

Hi..
If I'm not wrong, HFEJB is for EJB 2.0, and scbcd for EJB 2.0(i.e. SCBCD 4) is not being conducted anymore.
Manning EJB in Action is for SCBCD 5 i.e. for EJB 3.0, and ejb 2.0 and ejb 3.0 has quite a lot of differences, mainly in the syntax and classes to be written.
But what i suggest is to just have a slight idea on EJB 2.0 before going to EJB 3.0...
Then you will have a correct idea of whats happening!!!


Cheers,
Ravi.

Well, just as I said, at first I have read "EJB 3 in Action". And today I've started HFE. Fortunately at the very begin , I figure out that it's about EJB 2.0 specs.
I'm preparing SCBCD 5 exam, and I have "EJB 3 in Action", and also "Mastering EJB 3.0", for preparation (consulting sun's specs. of course).
hanks any way for warnings, and it is really pity, absence of 'HFE 3' book on market. The concept of all 'HF' editions is marvelous. Maybe we need to urge to Kathy Sierra, to go no and create one more educational 'master piece'

Hi Slobodan,

Yesterday i got the SCBCD certification, and i used principally the book "Enterprise JavaBeans 3.0, Fifth Edition by Richard Monson-Haefel, Bill Burke". This is a really good book. I have some years of experience in ejb3, but this is a good book for begin and to know almost every objectives in the exam and practice (have excercises with source code).

Good luck!

Thank you Manuel. Considering that, I would appreciate if you, or any one else who find itself able to provide me some help, take a look at my post about figuring out certain issues of MessageDriven Bean I have, which I post under "EJB and Other Java EE Technologies" topic , with the title Message Destination .
Thanks in advance folks!
