I'm having trouble signaling a process instance to advance beyond a wait activity.
I've looked at the jBPM example but no luck. I have a process definition with
numerous state activities. I created a lisetner for each activity. The listeners
(simulate) some external work then call the executionService.signalExecutionById()
method:
public void notify(EventListenerExecution execution) throws Exception {
System.out.println("MESSAGE: " + msg);
//Timer timer = new Timer();
//ExternalTaskProxy task = new ExternalTaskProxy();
//Date now = new Date();
//timer.schedule(task, now, 1500);
ExecutionService executionService = processEngine.getExecutionService();
executionService.signalExecutionById(execution.getId());
}
I deploy the business archive using an Ant script then run a process instance via the jBPM
console. The process instance starts but halts at the first activity. Here's the
process definition's jpdl code look like this:
<?xml version="1.0" encoding="UTF-8"?>
<process name="Simple Activity Scheduling"
xmlns="http://jbpm.org/4.0/jpdl">
<start g="188,25,48,48" name="start">

to="Activity1"/>
</start>
<state g="137,123,150,52" name="Activity1">
<on event="end">
<event-listener class="my.package.MyListener1"/>
</on>
<transition name="to Activity2" to="Activity2"
g="-138,-18"/>
</state>
<state g="137,220,152,52" name="Activity2">

</state>
<state g="165,739,92,52" name="Activity7">
<on event="start">

</on>
<transition name="to Activity8" to="Activity8"

</state>
<state g="142,846,139,52" name="Activity8">
<on event="start">
<event-listener class="my.package.MyListener8"/>
</on>
<transition name="to end" to="end"
g="-36,-18"/>
</state>
<end g="651,849,48,48" name="end"/>
</process>
Any help would be appreciated.
