[jboss-user] [JBoss jBPM] - Help needed : missing scheduler while testing a timer

[sonicfab]

Hi.
I'm testing a simple process with one node and a timer at that node, and I get the following error :

  | 16:34:23,466 INFO  [STDOUT] 16:34:23,466 ERROR [GraphElement] action threw exception: service 'scheduler' unavailable

My test setup is a simple servlet whose doGet method send a signal to the process :


  | ProcessDefinition processDefinition = ProcessDefinition.parseXmlString(
  | 				"<process-definition >"+
  | 				   "<start-state name=\"start'\">"+
  | 				      "<transition name=\"\" to=\"TimerNode\"></transition>"+
  | 				   "</start-state>"+
  | 				   "<node name=\"TimerNode\"> "+
  | 				   	"<timer name=\"testTimer\" "+
  | 				   		"duedate=\"1 business minute\" >"+
  | 				   	"</timer>"+
  | 				      "<transition name=\"\" to=\"end1\"></transition>"+
  | 				   "</node>"+
  | 				   "<end-state name=\"end1\"></end-state>"+
  | 				"</process-definition>"
  | 				);
  |         ProcessInstance instance = new ProcessInstance(processDefinition);
  |         
  |         instance.signal();
