I just want to ask which exam is good to take first. SCBCD or SCWCD?
I am novice for both. But I am currently assigned to an EJB kind of
Project. Lot of my friends would say to take SCWCD first since it is easy than SCBCD according to them. And I already coded some Web Component. I already bought the 2 books Head First Servlet and JSP and also Head First EJB. But I am still confused on which one to study first.
I am thinking of SCBCD since I am using it in my current project.
I really need a good advice. Thanks.
Theoretically speaking, it should not matter in which order you take SCWCD and SCBCD. Practically speaking, the following factors should be considered:
1) It depends upon which side of programming you are coming from? For example, if you are getting at J2EE from with end programming background, to do SCWCD first may be a better choice. While if you are coming from a backend programming, to do SCBCD first may be a good idea.
2) It also depends upon where you currently are in your career and where you are headed. In context of your job (or career), does it make more sense to do SCWCD or SCBCD today?
So, in your case it should be SCBCD first :-).

I have one question. Do you see any specific benefit in doing SCWCD before SCBCD? Will it add or make easy the study/understanding for SCBCD?

I purchased your book last week. This was after my very good experience with the SCWCD exam study kit by Deshmukh et al.
However I'm a little dissapointed right now. 4 days has gone and I havnt come any further than to trying to get the Fortune bean up. The appendix A doesnt seem to match my (latest? 2005Q1) version of suns application server. Neither does the book seem to give me enough information about writing the xml files properly myself to use another application server (like orion). Or perhaps its just me being really stupid. =) I'm not sure. I havnt changed any code in your examples. What I'm doing wrong?
Here are some error messages I received with todays experimentations. The first one is in swedish, but it basically says that runclient isnt a commando or a program:
1) E:\workspace\EJB-lekstuga>runclient -client FortuneApp.ear -name FortuneClient -textauth

I have passed SCWCD by preparing with HFSJ. Now I am planning to go for SCBCD. For SCWCD I didnt refer to the specs. I just read and worked out HFSJ. So only an author can say, what are all the things that we are missing out in the technology because of just referring to a study guide and passing the exam. If you can list out some thing, I will try myself to correct them atlease in EJBs.
And also, for these kind of specialization exams(SCWCD, SCBCD, SCDJWS) why do they have only online objective type exam. It would be better if they have some assignment submission. Why are they not doing it?.

Thank you for the question.
Yes, there are two more books from me in the pipe, both on Sun technology: SCJP (based on J2SE 5.0)and SCSA (Sun Certified System Administrator for Solaris 10). More information:
I would like to know whether you planned for writing any more books for Java certifications?
There are still some "buffers" available: SCJA, SCMAD & SCDJWS.

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.

I wish to ask the Author of SCBCD exam kit the following:
Does this book cover EJB 3.0 also that is to say does it give the readers an idea about how much transition or changes should be anticipated, if and when the new exam covering EJB 3.0 comes out. Does it specifically mentions where and how the complex parts would be simplified in future version EJB while explaining EJB 2.0 concepts.

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?

I downloaded your SCBCD Exam Study Kit ebook a few weeks ago and am about half way through it now. After reading the section on session beans there is one topic that I'm not sure I fully understand. Could you explain why resource manager access and access to other beans is permitted in an ejbCreate method for stateful session beans but is prohibited for stateless session beans?
