Hi folks,

Well I myself am new to EJB. Three quarters of the way through Head First EJB and planning to take the SCBCD exam shortly.

The reason I write is that I have grown slightly disheartened of late with my quest to learn about all things EJB.

Taking Stan up on his response, I also worked on a project where the architecture was such that you had a stateless session bean entry point and everything after that was delegated to POJO's. A Toplink layer provided the o/r mapping for persistence.

I am currently midway through the extensive Entity Bean chapters of my exam prep and I have began to question (a) Why am I studying something that seems to get bypassed all to regularly in favour of technologies such as JDO, Hibernate, Toplink etc, (b) Why am I studying an area that as I understand it was heavily revised between EJB specs 1.1 and 2.0 and will be again with 3.0.

Indeed, it seems to me that there is considerable discussion these days as to just how much value EJB adds. With books on the market such as 'Expert One on One J2EE Development without EJB', which comes from a seemingly highly regarded author, I'm really beginning to wonder.

Should I be focusing my energies on learning about the J2EE web tier instead. What future is predicted for EJB's? Will the industry start to look at alternatives for transaction management, security and everything else that EJB provides?

As I said I'm new to this so so any thoughts or inspiration would be much appreciated.

Regards
