Is it okay to pass injected EntityManagers to EJB bean's helper classes and use it?

Question

We have some JavaEE5 stateless EJB bean that passes the injected EntityManager to its helpers.

Is this safe? It has worked well until now, but I found out some Ora

Answer 1

Well, personally, I wouldn't like to have to pass the Entity Manager to all my POJOs in my constructors or methods. Especially for non-trivial programs where the number of POJOs is large.

I would try to create POJOs/HelperClasses that deal with the Entities returned by the EntityManager, instead of using the entitymanager directly.

If not possible, I guess I'd create a New EJB Bean.
