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

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();
