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

I've been using helper methods and passed the EntityManager there, and it is perfectly OK.

So I'd recommend either passing it to methods whenever needed, or make the helper a bean itself, inject it (using @EJB) and inject the EntityManager there as well.
