Using DAO for Part 2 Assignment:Still Relevant?

[Rahul Mishra]

Hi All,

What is your general perception on injecting Entity Manager directly into Stateless Session Beans to access entities and doing away with the clutter created by DAO Factories and DAO's.

Since the message is posted in SCEA Forum , i am looking for an answer with the exam perspective and not based on real life projects.

I am actually interested to know if someone has used the Entity Manager directly from Stateless Session Bean in their solution and passed.

Thanks,

[Jeanne Boyarsky]

Yes. This is an acceptable way of doing things.

Rahul,

Your approach is correct. You don't need DAO anymore for this scenario.

Venkat

But my evil twin tells me that this approach leads to entity access code being littered everywhere.

How do i convince my evil twin ? ;)

I'm not convinced that this is a good way of thinking about the exam.

I just googled and found this: http://www.infoq.com/news/2007/09/jpa-dao

In real life, I wouldn't put any custom code in a session bean. I'd delegate elsewhere. You asked about the exam where it is acceptable either way. In real life, it depends.
