Hello Friend, I am typically new to EJB concept.
Please suggest me, is there any need to have EJB2 knowledge before starting EJB3 or I can directly dive into EJB3.

You can and should jump directly into EJB 3. Indeed, I would never recommend anyone learn or work with EJB 2 unless they absolutely have to and I have used it since 2001/2002 myself. Although EJB 2 is a pioneering technology that brought many great ideas to the mainstream, it is really not very usable/productive compared to what is available today in terms of EJB 3, Spring and many others.

Thanks Reza,

Your suggestion made my voyage through EJB little bit easier. Now I can concentrate on EJB3 without fear of not having knowledge of previuos version.
I agree. Here's the link:
