I like to start reading about EJB and their concepts. My questions are

1. Which version of EJB i can start? People said EJB2.0 is not that good. Shall i start with EJB 3. Or do i need to read EJB 2 to know the basics?

2. Which book will be better and friendly for EJB beginners?

Well, the easiest book to read is Head First EJB. That covers EJB 2.x

I think a little bit of understanding how an App Server works is very helpful. Especially with the Classloader stuff, lookups, etc.

Then check out the EJB 3.0 specification.

Hi
EJB 3 is newer version and a very simplified version of EJB
it is better that you start with ejb3.
to start i suggest you get :
http://java.sun.com/javaee/5/docs/tutorial/doc/JavaEETutorial.pdf
and get the netbeans IDE to complete your learning toolset
http://www.netbeans.org/community/releases/55/

That tutorial make you familiar with ejb3 and netbeans allows you to implement those concepts easier.

I'm working my way through Head First EJB myself now and I'm quite impressed with it. It is written with the intent of getting the reader ready to pass the Sun Certified Business Component Developer exam. So, if you already have the SCJP certification, consider going for this one too. I've always found that studing for a certification is a really good way to make the material stick.

Hello Freind
First thing is that if you think ejb 3.0 is better then you should read ejb 3.0 but i think there is no much difference between 2. 3. secondthing is about book then till to now i have read Adroman (Mastering in ejb).but i suggest that any book on ejb read completely after that you can chose any which you like but Adroman cover all topic very well

Hi,
like many others before I was unable to find a working remote call / lookup example for EJB 3.0.

On the other hand if you do not urgently need it for the job then I would advise you to start with EJB 3.0 because it is really different and much easier and mor logical. But that means coding (well done in Eclipse 3.1.2) without real testing for the first time (how long? ...)
