Using a scheduler to repeat a simple task

[gwtLearner]

Hi there,
I am using smart gwt 2.2 and firefox.
Just need to have a simple Scheduler to repeat a task for example every 30 seconds.
Tried to used gwt Scheduler class and it works. This is the code:

 
	
	private final class LoadAlarmGrid implements RepeatingCommand{		
		public boolean execute() {			
			updateAlarmsGrid();
			return true;
		}		
	}

       Scheduler.get().scheduleFixedPeriod(new LoadAlarmGrid(), 30000);

Would anyone know how to stop the scheduler?

Thank you.
