Hello,
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).
Project1:
- CrudServiceBean.java
- CrudServiceLocal.java
Project2:
- CeraEmployee.java
- Persistence.xml
Project3:
- App.java
When I try to use some method of CrudServiceBean in App.java I get an exception, u201Ccom.sap.engine.lib.injection.InjectionException: Injection on field entityManager of instance co.com.crystal.util.CrudServiceBean@4e40f180 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?
Regards
Janeth
