Hi @all,

I've got (a) very simple question(s).
In most examples online several classes have got their own EntityManager.
I think it's a waste to have to many EntityManager, isn't it?
So I'd create one in a session bean (or realated) to it, so every session has exactly one EntityManager.
All other classes will have access to this class. Does this approach have any disadvantages?
Is there a reason/advantage to have several EntityManager per Session?

Cheers,
Glotzich
