    Method annotated with @Schedule invoked twice in a singletone bean

    freakyprogrammer Newbie

      I am running my application on Jboss 7.1.1-final. I have an EJB annotated with @Singleton which has a method which is annoated with @Schedule which I use to push messsages to JMS queue at the scheduled time. But when I deploy to server scheduler is invoked twice on every interval . My Scheduler Class is here



      public class SampleSch {
                private MessageProducerService messageProducerService_;
                @Schedule(minute="*/2", hour="*",second="20", persistent=false)
                public void pushMessage() {
         // emailMessage has just to,from,subject and email content which is pushed to JMS Queue   


      But Once server started after 2 minutes as scheduled it's invoked twice after two minutes at 20th second.


      15:12:20,037 INFO  [myclass] (EJB default - 7) ************ Scheduler started at *************
      15:12:20,037 INFO  [myclass] (EJB default - 7) ************ Calling pushMsgtoQueue method to put messages into the Queue *************

      push messages into Q at 2013/08/06 15:12:20  -----> Second invocation



      How Can I resolve this?
