[jboss-user] [JBoss jBPM] - about Jbpm scheduler

[rekyll]

Hello !

I have a problem about Jbpm scheduler.

My process definition file is:

  | ......
  | <task-node name="chiefCheck">
  | 		<task name="chiefCheckTask" swimlane="chief">
  | 			<timer duedate="10 seconds" repeat="5 seconds" name="chiefCheckTimer" transition="end">
  | 				<action class="com.rathink.bpm.example.askforleave.handler.action.ChiefCheckTimerActionHandler"/>
  | 			</timer>
  | 		</task>
  | 		<transition to="timeDecision" name="chiefCheckEnd"/>
  | 	</task-node>
  | ......
  | 




My jbpm.cfg.xml is like this:


  | <jbpm-context>
  | 		<service name="persistence" factory="org.jbpm.persistence.db.DbPersistenceServiceFactory"/>
