Hi,

I just went through your personal website, and I am pretty surprised with your profile (You, have been working with Computer Science & Physics, almost parallely...gr8).

Paul, today in Java Space there has been a lot of new specs , for example Tiger has released, Java 6 (the Mustang, in Beta probably) and Java 7 has been started to be talked about. Similarly, EJB 3.0 is not that far.
Also, EJB3.0 is a major change to its previous version (architectural change).

So, do you think the certification for 2.0 is worth (in terms of knowledge, leave the Job offers), as it is any way different from EJB 3.0.

Thanks !!!

Hello Anshu:
You are absolutely right that we are living in a constantly and rapidly changing world, and technology is not an exception. So, it's very important to keep up with it.
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 years before the SCBCD exam based on EJB 3.0 is released. Two years is a long time in this information age. 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.

Hope it helps.
Cheers.
Paul

Yes Paul/Nick, these reasons sound good.

In fact , I wish them to be around for longer (instead of just 2 yrs, since I've learned it putting a lot of effort, in pre Head First days :-( ).

But, now I feel most of the applications are using the combination of Spring/Hibernate to replace the existing EJB1.x or 2.x Solution. And the new applications are also using them. Correct me if I am wrong here.

By the way, I will be buying a copy of your book, whenever it will be available in India.

That's why EJB 3.0 makes use of the ideas of Hibernate.

I will go for EJB 3.0 as I believe J2EE will still be the major trend.

Yes Nick, I know it very well. Thanks for pointing again.Gavin King , the person behind the Hibernate is one of the main contributor to the EJB 3.0 , it is quite natural. In fact , Hibernate is really nice (O/R mapping soln).
