I'm trying to migrate a project from JBoss 4.0.4 to JBoss 6. The project consists of an EJB 3 backend and a MyFaces 1.1.4 frontend. I have included the MyFaces 1.1.4 libraries in the JBoss 6 jsf deployer.
I have a call from the frontend to a backend function through a helper class.
PatientControllerEJB patientModule = BusinessHelper.getPatientServices(); patientModule.canCreatePatVisit( getUserContainer().getClientId(), patId, vType);
After that call I get a NullPointerException at the backend canCreatePatVisit function, in the session bean patientModule.
@Stateless public class PatientControllerEJBBean extends ASBusinessLogicClass implements PatientControllerEJBLocal, PatientControllerEJBRemote { @Resource private SessionContext sessionCtx = null; @PersistenceContext(unitName="amedPU") EntityManager em; @EJB private AdminControllerEJBLocal admContr; @EJB private ConfigControllerEJBLocal confContr; ... public void canCreatePatVisit(int clientId, int patId, int visitTypeId) throws ValidationException { IVisitType vt = admContr.getVisitType(visitTypeId); ... } ... }
I debugged the project and I found out that em, admContr and confContr are all null. So I suppose there is a problem injecting a session bean in another session bean but I don't know what.
I have changed the web.xml version to 2.5 in the frontend and I am using the JBoss 6 libraries. Any help would be appreciated.
I'm including a portion of the stacktrace below in case it might be helpful.
