Welcome to the forum Sanghera,

Timing couldnot have been better.
I was looking forward to taking this exam soon.
Now i guess i have a great book .
But I just want your opinion on weather I should wait for a new exam with ejb 3.0 objectives or take the current exam ? Basically i have a timeframe of two months .

Thanks
Aneesh

Paul Sanghera,

Of the six EJB transaction types (Required, RequiresNew, Supports, NotSupported, Mandatory, Never), Required and RequiresNew seem pretty easy to understand, but some of the others are not so clear.

Supports seems to equate to "I don't care" and could be dangerous.

NotSupported and Never also seem like they should be avoided. Would it really hurt to use Required on RequiresNew instead?

Couldn't you use RequiresNew anywhere that you would use Mandatory and avoid the possibility of throwing a TransactionRequiredException?

thanks,
Paul

Hi Paul,


As a token of just how much faith we as the Java community all have in your book, my copy's been on backorder for over six weeks (and the store reckons another three more).

Looking forward to reading your answers this week, if I come up with a few decent questions of my own, I won't hesitate.


Regards,
Barend

Hi Paul,

I have a question on MDB. How can we maintain client side transaction in case of an MDB ?

Thanks

Paul, my additional question for you is, what EJB Container (o J2EE Server) you use in your new book?

Hi Paul,

I am not quite ready for the SCBCD exam (taking SCWCD in next couple of weeks), but thought I would say hi anyway.

To everybody, please remember that all questions you ask in this thread will not be taken into account for the drawing.

It's much better if you start a new thread with your question

Why to apply for the SCBCD for EJB 2.0 when we have EJB 3.0??

I want to apply the SCBCD for EJB 2.0 but I'm hesitating because of the presence of EJB 3.0.

Thank you very much for the introduction and for the opportunity. I'm honored to be here at JavaRanch. Please allow me to say three things:
1) Thanks to Kathy Sierra, Paul Wheaton, and others to give this great gift to the Java community.
2) Thanks to JavaRanchers to keep this place lively.
3) I take the liberty to share three pieces of information with you that will answer some of the questions, I already see on the forum:
a) The website for this book is:

From this website you can also go to the author online where readers can discuss the topics in the book and can ask me the questions.
b) If you are interested in knowing what other books from me are in the pipe, please check it out at

Aneesh and Jesus:
In my opinion, to take the SCBCD exam, you do not need to wait for the exam based on EJB 3.0 for the following three reasons:
1)It's going to take about two (may be as long as three) years for the industry to substantially move to EJB 3.0, and the exam will most likely not be released until that happens. I won't freeze my career for that long.
2) There is a large enough install base for EJB 1.1 and 2.0, so the knowledge of and experience with EJB 2.0, and the corresponding certification will be valuable credential for any Java developer and an asset for the employer.
3) One of the main goals of EJB 3.0 is to make the development "easier" than it is now. That means any developer with EJB 2.0 background working with EJB 3.0 will have relatively deeper understanding of some concepts.

Yes, with an SCJP certification (which is a pre-requisite for this exam) under your belt, two months is a reasonable period to prepare for the SCBCD exam.
Good luck, Aneesh.
Paul
