They are making it simple!!!

After putting all those efforts into learning EJB, the guys are coming back to POJOs and POJIs (i.e. plain old Java Objects and plain old java interfaces!). First I felt cheated. Learning EJB will be so easy for new people now! Then I felt oh.. so many things to un-learn and re-learn!!

But then, it is human nature to resist change at first. Will life be better? Will it be a huge change for systems already implemented in the earlier versions of EJB?

Waiting for your valued comments.

EJB 3.0 First Draft

There is no reason to feel cheated. If you understand the current EJB specification than learning the new "simplified" EJB 3.0 will be a breeze. The other important thing to remember is that there are a ton of applications in the field that are currently using EJB and will need support for years to come. EJB 2.0 has been out for years... yet I work with numerous clients that are still on EJB 1.1. EJB 3.0 is at least 18 to 24 months away from being released... how soon do you realistically expect companies to begin using it?

Rest assured that you will reap benefit from your EJB 1.1/2.0 knowledge for years to come.

Leena,
While there is less code, the concepts are still the same.

"Removing need of interfaces and deployment descriptors and these may be generated by the container using metadata annotations"
This is a good example of what I mean. The container is generating the code for you. But you still need to understand what is going on.

EJB 3.0 In Nutshell

so many things to un-learn and re-learn!!

EJB 3.0 changes are to be appreciated. Sun is making things simpler which is welcome. Nothing is permanent expect Change

As Chris mentioned it will take some time before we start using it. Jboss has made EJB 3.0 preview available.
