    A question about the scheduler

    Yair Zaslavsky Newbie

      Hi, I want to write a JMX service that upon the activation of its "test" method, a perioudic job will begin.

      I added the following lines to the jboss-service.xml:







      I then wrote the interface of the service:

      @Local
      @Remote
      public interface TestTimer
      {
      public void test();
      }


      And then I implemented the service itself:
      @Service (objectName="trail:service=TestTimer")
      @Management(TestTimer.class)
      @Depends ("acme:service=Scheduler")
      public class TestTimerMBean implements TestTimer, Schedulable {
      private SchedulerMBean schedulerMBean;
      public void test()
      {
      try
      {
      System.out.println("Hello time " + System.currentTimeMillis());

      MBeanServer server = MBeanServerLocator.locate();

      schedulerMBean = (SchedulerMBean) MBeanProxyExt.create(
      SchedulerMBean.class,
      "acme:service=Scheduler",
      server);

      if (schedulerMBean != null)
      System.out.println("succeeded in looking up scheduler");


      System.out.println("@@@@@My class name is " + getClass().getName());
      schedulerMBean.setSchedulableClass(getClass().getName());
      schedulerMBean.setInitialRepetitions(20);
      schedulerMBean.setInitialStartDate("NOW");
      schedulerMBean.setSchedulePeriod(2000);
      schedulerMBean.start();
      schedulerMBean.startSchedule();
      }
      catch (Exception e)
      {
      e.printStackTrace();
      }

      }

      public void perform(Date arg0, long arg1) {
      // TODO Auto-generated method stub


      try
      {
      File f = new File("c:\\sched.txt");

      FileOutputStream fos = new FileOutputStream(f,f.exists());
      fos.write(("date is " + arg0 + "arg is " + arg1).getBytes());
      fos.close();
      }
      catch (Exception e)
      {
      e.printStackTrace();
      }
      }
      }


      When I deploy, I can see that there is a perioudic job that runs, but I dont see that the method "perform" is executed (the file c:\sched.txt is not created and i do have permissions - i also tried using system.out.println - and nothing - the jboss application server runs on my machine )
      What am I doing wrong here?

      Thanks
