Hi,

I'm working on a EJB 3.0 + Hibernate project.
I've decided to use an application managed EntityManager instead of a container managed EntityManagaer.

I'm creating the EntityManager using an EntityManagerFactory and in another class, I'm using @PersistenceUnit(name="myName") to try and inject the EntityManager I've created into an EntityManager class member (The persistence unit is defined in persistence.xml).

The problem is that the injection doesn't work and I get a null value.

I'm assuming that I can use entity injection by using @PersistenceUnit even without a container?
Any ideas what I'm doing wrong?

Hi,

I believe @PersistenceUnit injection should work as well, but this is really a question specific to the container you are using.

Hi,

I stated in my original message that it's an application managed EntityManager and that I wasn't using a container.....

Is @PersistenceUnit only supported within a container?

Hi,

@PersistenceUnit is still an annotation 'consumed' by the container. The difference is that @PersistenceUnit gives the developer more control over the entity manager regarding creation and deletion. Using @PersistenceContext the container will be responsible for the life cycle of the entity manager.
