I dont have the unit test case but the basic code is below:
*Sample Workflow:*
<?xml version="1.0" encoding="UTF-8"?>
<process name="TEST" xmlns="http://jbpm.org/4.3/jpdl">
<start g="0,0,80,40">
<transition to="theEnd" />
</start>
<end g="135,72,80,40" name="theEnd" />
<on event="start">
<event-listener class="WorkflowStatusEvent">
<field name="transactionId" cache="disabled">
<object expr="#{id}" />
</field>
<field name="status" >
<string value="IN_PROGRESS" />
</field>
<field name="tcn" cache="disabled">
<object expr="#{param1}" />
</field>
</event-listener>
</on>
<on event="end">
<event-listener class="WorkflowStatusEvent">
<field name="transactionId" cache="disabled">
<object expr="#{id}" />
</field>
<field name="status">
<string value="COMPLETED" />
</field>
<field name="tcn" cache="disabled">
<object expr="#{param1}" />
</field>
</event-listener>
</on>
</process>
*Event Listener Code:*
public class WorkflowStatusEvent implements EventListener {
Logger log = Logger.getLogger(WorkflowStatusEvent.class);
//value gets injected from process definition
String transactionId;
String status;
String tcn;
public void notify(EventListenerExecution execution) {
log.info( transactionId+" -- " + status);
log.info(tcn);
}
}
*Code starting the business process:*
for (i = 0 ; i < 2 ; i++) {
Map<String, Object> parameters = new HashMap<String, Object>();
parameters.put("param1", Integer.toString(i));
parameters.put("param2", Integer.toString(i));
parameters.put("id", Integer.toString(i));
executionService.startProcessInstanceByKey("TEST",parameters);
}
The SOPL in the Event listener displays the value of first cycle event if the value of i = 2.
