Hi Guys,

I wanted to start learning EJB , but I am not sure which version to start with

Are EJB 2.x and 3.x fundamentally different ? I mean apart from coding stuff , are there any major architectural changes ...

Please present your point of view ....

Thanks

There are company's which still uses EJB 1.1. So it up to your Job. If you are going to work in EJB, you know which version to learn.

If you are learning your self better to go with EJB 3.0

HERE is link which will explain you how EJB 2,0 entity bean differ from EJB 3.0 entity beans.

THIS link will tell you what is new in EJB 3.0?

It's the same conceptually. I would start with EJB 3.0 and then later learn the syntax for EJB 2.1.
 
Story like this gets better after being told a few times. Or maybe it's just a tiny ad:
