Since the book is based on the EJB 2.0 specification, is it on the J2EE 1.4 Platform? I heard that the beta exam of SCWCD will be launched in coming January. That exam is typically designed for J2EE 1.4 Platform, isn't it?
I just would like to know whether the current SCBCD exam is on J2EE 1.4 or not so that I can know that Head First EJB book is written, according to which version of J2EE Platform...
Thank you in advance...

hello Ko Ko,
I'm neither Kathy or Bert, but I'll give an answer anyway - hopefully it's the right one.
The SCBCD is based on the EJB 2.0 specification and will be for a long time.
That's all you need to now.
To my knowledge J2EE 1.4 is using EJB 2.1 specification, so don't use features in EJB 2.1 if you want to try it out!
Cheers
Erik

Erik Kaellgren,
It is very nice that you answer for the others instead...
Do u mean that the EJB 2.1 will not be used in the industry for a long time? And do u mean that EJB 2.0 will be the main version for EJB developers for two or three years?
I just would like to know whether I should adapt to the EJB 2.1 directly or just have to be satisfied with version 2.0 at this moment...
It is very kind of you that you got some answers for me...
Thank you very much...

EJB 2.0 is a part of J2EE V 1.3 spec. There are many application which still use EJB 1.2 version.
EJB 2.1 will be a part of J2EE v 1.4. If I am not wrong some people are working on EJB 3.0 spec as well.

I was just wondering if the SCBCD certification will be updated with EJB 2.1 version after J2EE V 1.4 is released?

Oh, really? The current exam is just launched and still fresh... But the J2EE V1.4 will be released soon... I guess they might not update the exam so quickly like this... But we have to wait and see...
Thank you for your information too...

Ko Ko,
1) for the certification you should concentrate on EJB 2.0 specification for the time being.
2) the general problem with new releases is that it takes a long time to be used in the industry.
For example, Weblogic is always faster to implement a new release of j2ee than Websphere.
Also, you might work for a company that still uses Webshpere 4.0 and then you can not even use EJB 2.0!
If you're a student you probably go for the latest version to learn, not only for a certificate, but for life.
Otherwise you need to be more pragmatic. An example, the other day I saw a customer that wanted somebody to
work on a JDK 1.0 (yes) applet to make it work in a new environment.
So you really need to be flexible!
Hope it wasn't too confusing!
Cheers
Erik

There NO "EJB 1.2 version"
avalable specifications are : 1.0, 1.1, 2.0 (for current version of SCBCD) and 2.1

Oops... I overlooked that mistake too...
So let's concentrate for EJB version 2.0 towards SCBCD....
I think Head First EJB book will be very popular, like SCWCD Exam Study Kit of Hanumant, which is an essential book for SCWCD Exam...

Is it really that the development team is currently working on EJB 3.0?
Why are the technologies running so fast?
We can't follow them anymore, can we? :roll:

I see... U mean that they are the one who always updating the version of EJB... Once I heard that JCP is composed of many big organizations, I think BEA and IBM is also in JCP, aren't they?

There are a lot of organizations in JCP as well as medium-size companies...
Thank you for introducing me about the JCP... I got some knowledge about it now...

As I understand it, the intent is to show that you understand, and can use, EJB's today, not some vague time in the future when the major players support the new spec.

Hi Ko Ko,
Sun decided (and we agree), that the SCBCD exam should be based on J2EE 1.3 and EJB 2.0. The thinking is that EJB systems are so large that migration is a BIG DEAL, and very few companies will be using J2EE 1.4 and EJB 2.1 any time soon.
I think it's pretty safe to say that the exam won't be updated for 12 to 18 months - don't wait!

That's a good information... Coz I have been planning SCBCD with the worry that it will be updated, when J2EE 1.4 is released... But I heard that it is sure that the beta version of SCWCD will be launched in coming January... So the SCWCD will be up-to-date to J2EE 1.4 and the current version of SCBCD will be long for at least one year ahead...
Thank you for your information, Bert...
