Hi,

I havent done much of programming using EJB 2.

So now i wish to get to know about them....What do you suggest...

Learn it from EJB 2 and then progress to EJB 3.

What are the resources available for EJB 3.

Regards

JBoss is an open source application server which you can start using. There are many others servers too. The current versions of JBoss support EJB3.

which way is better to go...start off with EJB 3 or graduate from EJB 2 to EJB 3...



My personal opinion is that its better to start off with EJB 2 and then move to EJB 3. Once you are familiar with EJB 2, moving to EJB 3 will not be a big deal, even though EJB 3 has some drastic changes.

Lot of J2EE applications are running on EJB 2.0. Regarding EJB 3.0 not sure whether it will take off. Lot of investments have also gone into OR frameworks like Hibernate.
 
It's a tiny ad. At least, that's what she said.
