Getting reference on Persistence Unit

[straiver]

I have 2 jar files. The first one is dao and the second one is domain logic.
After deployment DAO sets own persistence unit.
But when I'm trying to get reference on it from domain.jar:

@PersistenceContext(unitName = "name_from_dao")
private EntityManager manager;

Jboss issue is

Persistence Unit NOTYETINSTALLED

After putting classes from domain.jar to dao.jar, deployment successful.

What's the cause of this bug? Maybe I must add someone additional deployment descriptor to domain.jar?

How are you deploying the jar files, in a single ear, or as 2 seperate jar files in the deploy directory ?

as 2 seperate jar files

I am assuming that the DAO has some kind of persistence.xml where you specify the persistence unit. Why not deploy both jars within a single .ear archive, and then have the persistence.xml in a lib directory in the base level of the archive, this will allow both jar's to use the same persistence unit.
