I have a generic crud component (an EJB called CrudServiceBean) which has an EntityManager such as attribute and in other project some entities (with JPA).






- Persistence.xml



When I try to use some method of CrudServiceBean in I get an exception, Injection on field entityManager of instance failed. Could not get a value to be injected from the factoryu201D

But the persistence.xml file (with the persistence unit ) is in the entity project because the generic crud will be used in many entities projects, so how can I use my generic crud component out of the entity project?

    Hi Janeth,

    As long as Project1 and Project2 are part of the same EAR, that should be fine.

    Please look into the defaultTrace.trc file for the cause exception that would explain the "Could not get a value to be injected from the factory" thing.
