Sequence of SCWCD vs SCBCD and SCDJWS

Hi -

I'm wondering what Charles would recommend as to the sequence of the web component and services exams? Should SCWCD be first and then SCBCD followed by SCDJWS or some other order?

Thanks,
Brian

I haven't studied for SCBCD or SCDJWS - I did look at the objectives for each, but thought they looked really quite dry. And there is always a debate about the EJB tier of the platform being too bloated (which is becoming less true as things are starting to simplify with more standardisation in newer releases of Java EE). Really which you take is a matter of priorities. I am tempted to say that SCWCD is more useful to do before SCDJWS as you'll probably find yourself deploying Web services alongside other Web components, but you may not - it all depends! SCBCD can be done pretty much any time you like.

If I were to choose just one of these certification programmes to sit, it'd be SCWCD (obviously, else I wouldn't be here promoting it!!), for the reason that it's more interesting and lets me show my work off more to colleagues and other clients. Plus EJBs are usually overkill for the sorts of Java EE projects I work on, where a combination of POJOs and JPA often suffices.

I think SCWCD should be studied first followed by either BCD or DJWS

Ideally speaking, the order should not matter here as each are on its own track. WCD and BCD can be taken at any order, in my opinion.

But still, Web Component can give some good knowledge for Web Services. -- But not sure of it though.

I would disagree - WCD is basic compared to BCD and DJWS. DJWS can involve a lot of theory..

You don't need to have a knowledge about servlet/jsp designing to complete SCBCD.

Even the sun training goes through JSP/ servlets before talking about BCD.

Yep, it is 'better' to take SCWCD before going for SCBCD. But that is not 'required' to complete SCBCD.

Of course...it is better to learn the basic concept before diving into the BCD DJWS exams. If basics are not clear then you will end up in learning JSP servlet concept during your BCD exams.

I did my DJWS even before SCJP since I got free beta exam signup and jumped onto it.

Na, EJB technology is not only for web application development.

Please elaborate... Also which book covers BCD without needed basic information from WCD.

Books? Simply you can use EJBs for running your business logic of a swing application, or any other type of application other than a web application. Anyway this forum is not the place for a discussion about EJBs

Guys, the interpretation could very well vary. But BCD is not really dependent on WCD or JWS.

It is totally different technology and may be you can have a client (EJB client) as a Servlet or JSP (which would be like yet another client similar to a stand alone Java class).
