Hi Ranchers,

I just started with SCBCD 5.0 preparations, I feel like I am in a maze and feeling kind of difficult to get plunged inside EJB. It would be great if some one could give me a hierarchy of concepts or order in which various concepts are to be studied to get better understanding.

I am new to EJB, I am a novice...I have just heard people talking about various key terms in EJB and have never got an chance to work or study anything with respect to this. Hence I would like know this concepts hierarchy from the basics.

I guess there would be may more people of my category. It would be of great help to us.

Thanks a lot for your time

Regards,

It's kinda difficult to give you a hierarchy of topics. The certification give you a list of objectives. I would recommend you to go objective by objective (just like Mikalai Zaikin notes do). Mikalai Zaikin Notes

Its also very helpful to read about the experiences of people that already passed the test. Wall of Fame

Anyway, the following is a VERY VERY little list of topics that should help you to start studying:

1- Enterprise JavaBeans: Session Beans (Stateless, Stateful) - Message-Driven Beans. (They are components, they can not live outside of the container)

2- JPA (Object-Relational mapping): Entity Beans (They are POJO's, they can live outside of the container). Entity Beans lifecycle management: Entity Managers, Persistence Contexts (Transaction-scope, Extended).

3- Interceptors.
4- Transactions.
5- Exception handling.
6- Security.

This is just like an overview of topics, there are SOME MANY subjects missing here that you'll be finding in your study path (Roles, EJB 2.x Interoperability, Restrictions, Requirements, etc etc etc.). This is just to help you start.
