Hi,

I have Interface which is defined as

@Local
public interface MyPersistenceManagerLocal {

  public List getPropertyList(int id);

}

and implentaion class for above interface is

@Stateless
public class MyPersistenceManagerBean implements MyPersistenceManagerLocal {

  @PersistenceContext(unitName = PersistentSettings.PERSIST_NAME)
  private EntityManager entityManager;

  @Override
  public List getPropertyList(int id) {
    System.out.println("inside MyPersistenceManagerBean.getPropertyList()");
    ......
 ......
 ......
  }
}

and i am calling this in another class

@Stateless
public class ClientImpl implements Client {

  @EJB
  MyPersistenceManagerLocal persistenceManager;

  final List dbList = persistenceManager.getPropertyList(id);

}
 
 i am getting NullPointerException on
  final List dbList = persistenceManager.getPropertyList(id);
in debug mode i got persistenceManager is null.

i am new in EJB and JPA not able to solve this. any help why i am getting persistenceManager as null
 

is your persistence context properly defined in persistence.xml file and named according to your PersistentSettings.PERSIST_NAME constant value?
