[jboss-user] [JBoss jBPM] - Re: Please help me, 'scheduler' unavailable ??

[EugeneV]

I am getting a similar error and cannot fix it the way suggested above.

I created a new Process Project in Eclipse (with JBoss jBPM plugin) and checked the option to "Generate simple process definition, action handler and JUnit test". It worked fine. Then I added a timer to the middle State:

   
  | <state name="first">
  |       <timer duedate='30 seconds'>
  |          <action name="action" class="com.sample.action.MessageActionHandler" />
  |       </timer>
  |       <transition name="to_end" to="end">
  |          <action name="action" class="com.sample.action.MessageActionHandler">
  |             <message>About to finish!</message>
  |          </action>
  |       </transition>
  |    </state>
  | 

Now I'm getting an error:

  | 14:50:48,888 [main] DEBUG GraphElement : executing action 'CreateTimerAction(544ec1)'
  | 14:50:48,888 [main] DEBUG GraphElement : event 'timer-create' on 'State(wait for completion event)' for 'Token(/)'
  | 14:50:48,904 [main] ERROR GraphElement : action threw exception: service 'scheduler' unavailable
  | 
and the stacktrace is:
