ViewSscoped JSF bean & stateless that injects entityManager?
Hello,
Using TomEE 1.7.1 with JSF 2.2 I have a problem. Basically I have a bean
with javax.faces.view.ViewScoped and a Stateless that injects
EntityManager. I use Eclipselink.
This is my producer:
public class EntityManagerProducer {
@PersistenceContext(unitName = APP_NAME)
private EntityManager entityManager;
@Produces
@RequestScoped
protected EntityManager createEntityManager() {
return this.entityManager;
}
}
Passivation capable beans must satisfy passivation capable dependencies
happens pointing out my JSF bean. If I use private transient EntityManager
em; it works but it feels strange.
Any ideas?
cheers

OK so I will refactor so my controller is @RequestScoped but this use case
should be supported in java ee imo. That is- ViewScoped JSF bean and a
stateless that uses JPA...
Thanks for the help guys <3

stateless != state-less ;). Stateless bean have can have a thread safe
state. You just don't know which instance you get.

Why would you want your stateless to be serialized? Still not very used of
using EJB so for me it it's not intuitive because there's no state?

Hello sorry for what might be stupid questions but are stateless beans
serializable?

Hi
EntityManager is not serializable (its contract) so it can't be
injected in a passivation capable bean. fact it works with transent
field is cause it is serializable then.
IIRC CDI 1.1 relaxed a bit it enforcing implementation to be serializable.
