    EJB 3.1 Timer problems in scheduling recurring task

    Andrea Bennati Newbie

      I'm trying to use an EJB 3.1 Timer to schedule a recurring task every 5 minutes.

      I'm using JBOSS 6.0.0.Final.

       

      This is the simple code I have deployed:

       

       

      import javax.ejb.Schedule;
      import javax.ejb.Stateless;
      import javax.ejb.Timeout;
      /**
      * Session Bean implementation class AlerMonitorBean
      */
      @Stateless
      public class AlerMonitorBean {
          /**
           * Default constructor.
           */
          public AlerMonitorBean() {
              // TODO Auto-generated constructor stub
          }
         
          @Schedule(minute="0/5")
          public void GestisciAlert() {
               System.out.println("Gestisti Alert - Tick"+System.currentTimeMillis());
          }
         
          @Timeout
          public void GestisciTimeout(){
               System.out.println("Timeout");

       

      }

      }

       

       

      import javax.ejb.Schedule;

      import javax.ejb.Stateless;

      import javax.ejb.Timeout;

       

      /**

      * Session Bean implementation class AlerMonitorBean

      */

      @Stateless

      public class AlerMonitorBean {

       

          /**

           * Default constructor.

           */

          public AlerMonitorBean() {

              // TODO Auto-generated constructor stub

          }

       

          @Schedule(minute="*/5")

          public void GestisciAlert() {

          System.out.println("Gestisti Alert - Tick -> "+System.currentTimeMillis());

              //TODO: insert code

          }   

      }

       

       

      I notice the following in Jboss Console:

      I expected that method "GestisciAlert" was called once every 5 minutes.....

       

      Every 5 minutes Timer starts and activates target method several times (about once per second) for a minute....

      Then it stops and starts again after 4 minutes.

       

      Hope someone can help me.

          The syntax you are using is correct. So it should have fired once every 5 minutes. Can you try this - change that timeout method to:

           

          @Schedule(minute="*/5")
              public void GestisciAlert(javax.ejb.Timer timer) {
                System.out.println("Gestisti  Alert for timer: " + timer + " - Tick -> "+System.currentTimeMillis());
              }   
          

           

          And post that output.

            I obtain the following error:

             

            ERROR [org.jboss.kernel.plugins.dependency.AbstractKernelController] Error installing to Start: name=jboss.j2ee:ear=SoaEAR.ear,jar=SoaTimerEJB.jar,name=AlerMonitorBean,service=EJB3 state=Create: java.lang.IllegalStateException: Could not find timeout method: soa.schedule.AlerMonitorBean.GestisciAlert()

              That's strange. Can you post the entire exception stacktrace?

                I think I know what the problem is. There was a thread here which discussed something similar. Basically, the @Schedule by default creates a persistent timer. The @Schedule is expected to create an auto-timer on deployment of the bean. But ideally, it should not create the auto timer for an already persisted timer (or it should clear off the previous instance). I think there was a JIRA for this one, which I probably missed for 6.0 Final. Let me find that thread first.

                 

                For now, delete the JBOSS_HOME/server/<servername>/data folder and as a workaround, use:

                 

                @Schedule(minute="*/5", persistent="false")

                That should get you past these issues.

                    I think I know what the problem is. There was a thread here which discussed something similar.

                    ...

                    I think there was a JIRA for this one, which I probably missed for 6.0 Final. Let me find that thread first.

                     

                    Aaaahhhh! unfortunately, this never made it to the JIRA http://community.jboss.org/message/562006#562006

                      @Schedule(minute="*/5", persistent="false")

                      Applying this workaround the scheduled method never start.

                        As per EJB3.1 spec, by default the "hour" value is 0. Which means that it will fire every 5 minutes at midnight (when hour == 0 for an hour).

                         

                        What you want is:

                         

                        @Schedule(minute=”*/5”, hour=”*”, persistent="false")
