How to (re)start or stop the default Timer ?

[serkan.s.eskici.online.nl]

Hi,

I'm using the default Timer in Seam to start asynchronous or interval jobs with the @Duration and @Interval annotations.

But I don't know how to stop and restart an interval job that is already running.

I can't use @In Timer since this is the EJB timer and I get exceptions if I do this.

Any help or tip is appreciated, thx !

Hi,

Let's assume you have a class with following method:

class YourTimer ...

@Transactional
@Asynchronous
public QuartzTriggerHandle checkMessages(@Expiration Date when,
          @IntervalDuration Long interval, @FinalExpiration Date endDate){                 process();
     return null;
     }

This timer is called from a bean YourBean:

class YourBean ....

@In(create=true) YourTimer yourTimer;

private QuartzTriggerHandle timerHandle;

Which  somewhere in the bean calls:

timerHandle = yourTimer.checkMessages(cal.getTime(), 600000L, null);

After the call you have a handle of the timer and you can do what you want.
Although it looks strange. The Timer method is intercepted, so it returns a handle instead of the null.

Hopefully this helps a bit.
