    Need help with Timer in Seam application

    Natalia Ponomareva Newbie

      Hey guys, i hope somebody would be able to help.
      I am using timer service of EJB in a Seam application. When method marked as @TimeOut is called, i am getting

      Error invoking ejbTimeout: javax.ejb.EJBTransactionRolledbackException: java.lang.NullPointerException: facesContext

      I have no clue what facesContext it is looking for??? in my bean there is no any links to it. All the methods along work fine, but when @Timeout is called, the methods of ejb services fail with that exception.
      The souce code
      @SuppressWarnings({"unchecked"})
      @Stateless
      @Name("jobsTimerService")
      public class JobsTimerServiceImpl implements JobsTimerService {
       //in hours
       public final static int DUE_DATE_EXPIRATION_INTERVAL_IN_HOURS=2;
      
       @In(create = true)
       EmailHelper emailHelper;
      
       @Resource
       javax.ejb.TimerService timerService;
      
       @EJB
       AdditionalService additionalService
      
       @EJB
       UsersService usersService;
      
       @Logger
       private Log log;
      
       public void createTimer(long intervalDuration, String info) {
       Timer timer = timerService.createTimer(intervalDuration, intervalDuration,info);
       }
      
       @Timeout
       public void timeout(Timer timer) {
       sendNotifications();
       }
      
      
       public void sendNotifications(){
       List<User> recepients=getRecipients();
       //usually it fails in the next method!!!!!
       List objects=getObjects();
       emailHelper.send(recepients,wires);
       }
      
       }
      
       public List getObjects(){
       //using additionalService, getting the list of objects
       }
      
       public List<User> getRecipients() {
       //using usersService.. getting the list of users
       }
      
      }

      I have killed a lot time trying to find out what is wrong. If i invoke sendNotifications from UI of application, it works perfectly fine!!
      Thanks for attention

              I guess it has something to do with permissions for loading entities, since i think my class when it is called through timeout callback doesn't have those permissions. How do i fix that?

                In think you should focus on the NPE.

                You may have an observer (Expressions$2.invoke) of the event (Events.raiseEvent) "org.jboss.seam.notLoggedIn" (Identity.checkPermission) which is causing the trouble. This should be located in the components.xml Some MethodBinding/MethodExpression that is failing. You may need to post some more code if you cannot figure it out by yourself.

                  What version of Seam is this?

                    Thanks for responses!
                    Seam
                    Created-By: 1.5.0_07-87 ("Apple Computer, Inc.")
                    Seam-Version: 1.2.1.GAImplementation-Version: 1.2.1.GA

                    Also, wise_guybg, you are correct about the org.jboss.seam.notLoggedIn" component in components.xml/ Howerver, removing that doesn't solve the problem. It throws NotLoggedInExcpetion while trying to load the entity. The funny thing i noticed is the following.
                    If i load an entity that doesn't have a collection (lazy fetch type), the entity is loaded fine. but when i am trying to get entity with collections, the excpetion is thrown. Even the authentification in method doesn't solve that problem

                    Identity identity = new Identity();
                     identity.setUsername(TEST_USERNAME);
                     AuthenticatorImpl authenticator = new AuthenticatorImpl();
                     authenticator.setIdentity(identity);
                     authenticator.setEntityManager(em);
                     authenticator.setLog(Logging.getLog(Authenticator.class));
                     authenticator.authenticate();
                     authenticator.setActor(new Actor());

                    I have a temproraily fix -getting the properties this way
                    Query query= em.createQuery
                     ("select new map(r.id as id, r.amount as amount, r.createdDate as created, " +
                     "r.dueDate as due, r.reference as reference, r.status as status, r.createdBy as who) " +
                     "from WireTransferRequest r where r.dueDate >= :beginDate and r.dueDate <= :endDate"+
                     " and r.status<>:status" )
                     .setParameter("beginDate", beginDate)
                     .setParameter("endDate", endDate)
                     .setParameter("status", Status.TRANSMITTED);

                    and then creating objects and setting the pulled properties, but still wondering if there is a nice fix for that
