Abiodun,

I am preparing for taking the test and I recently passed the scbcd exam. I am finding it helpful really in the simulators.

There are some quirks between ejb 1.0 and 2.0 but it really hasn't presented me a problem yet.

Also, I have all my notes (paper based - sorry), which of course helps in the process...

You should consider the scbcd, it's fairly easy after reading the Head First EJB book.

Thanx I guess i would sit for the SCBCD, Only that i really don't know the importance of the exam because most companies don't use EJB

I agree, it calls into question also the usefullness of the SCEA since EJB is not used very often anymore...

Hopefully it will be updated soon...

I'm not sure what companies you are referring to not using EJB but there are quite a lot of organisations still implementing Session EJBs and the occasional odd Entity EJB (used as a Composite Entity) when appropriate. The return of the "service" concept has enforced the importance of using a Session Facade pattern on (if appropriate) Application Controllers.

I assume you are referring to Entity not Session EJBs?

Ian,

I am refering to any sort of ejb's. The Fortune 500 clients I have consulted to over the last 3 years or so have looked to Hibernate and Spring for their needs, bypassing ejb's altogether. There have even been some wholesale retrofits in order to rid themselves of ejb's.

I only consult in Colorado though, not sure what is going on in the rest of the country but, when I attended JavaOne recently it seemed to be that EJB was going the way of the dodo based on the popularity of Spring/Hibernate and all the folks I met and their experiences.

It's as if folks out there are looking for anything that doesn't require as much overhead in both the case of session and entity beens.

Not trying to be negative, I just don't know how relavent the EJB technology is anymore honestly...Hopefully 3.0 will bring the focus back to Sun approved technologies etc...it looks like it might...
