I have the Head First EJB book. I am not sure about the "depth" required in this topic for SCEA-1. Could someone please provide guidance? Would these chapters suffice?

2. EJB Architecture
3. Exposing Yourself: the client view
4. Being a session bean
5. Entities are persistent
8. Getting the message?

There are other chapters going into EJB, Transactions, Deployment etc.

I think the answer is less complicated than you're making the question.

To do well on the SCEA as it exists, you have to think about how Sun designed their program (meaning role-based) - they divide, rather clearly, the tasks assigned to an architect and those assigned to a developer. That being the case, you're required to understand the basics of the technology and the theories behind EJB 1.1, but you're not required to understand how to write the code to create one, or how it's deployed. If you have a basic understanding of the technology, you should do fine.

That said... I'd be careful, since I believe HF EJB is based on the 2.1 spec, not the 1.1 that the current SCEA (nor the EJB 3 that the upcoming beta) is based on.

On my SCEA resource page, I have a file called "ejb for scea" which covers what you need - and more. You should have a good understanding of the concepts of EJB first, but details are not necessary.
