Well thanks.
I followed the example of code in CreateTimerAction and CancelTimerAction (and switched
from jbpm 3.0.2 to 3.1.2) and now I can see my timers in the DB. But when I try to set an
Action to be called when the timer fires, I got an error.
Here is my related code:
anonymous wrote : Action timerAction = new Action();
| Delegation delegation = new Delegation();
| delegation.setClassName("logique.alerte.TimerHandler");
| timerAction.setActionDelegation(delegation);
| String sDueDate = "5 minutes";
| String sTimerName = "bob";
| Date dDueDate = businessCalendar.add( new Date(), duration );
|
| Timer timer = new Timer(executionContext.getToken());
| timer.setName(sTimerName);
| timer.setDueDate(dDueDate);
| timer.setAction(timerAction);
| timer.setGraphElement(executionContext.getEventSource());
|
| SchedulerService schedulerService = (SchedulerService)
Services.getCurrentService(Services.SERVICENAME_SCHEDULER);
| schedulerService.createTimer(timer);
And here is the error:

So how can I save the Action before closing the session ?
