Hi Maciej :
Thanks a lot for your sample code. And by that, I finally figured out why my call \
does not work. The way we call the "deploy process definition", and "start process \
instance", and "signal execution" is by 3 persons (or 3 stages) to simulate a \
business facility. So my work is providing a utility for them to execute and call. \
But your sample code is doing all of them in one-shot (from deploy PD, to signal \
execution). My utility is like the following and got executed by parameters such as \
(-deploy, -start, -signal, etc):
private synchronized void initJbpmEngine()
{
//
// got called when this utility class instantiated.
//
if (processEngine != null)
return;
configuration = new Configuration();
processEngine = configuration.buildProcessEngine();
out("Process Engine Identity Hash Code: " + \
System.identityHashCode(processEngine));
repositoryService = processEngine.get(RepositoryService.class);
executionService = processEngine.getExecutionService();
historyService = processEngine.getHistoryService();
managementService = processEngine.getManagementService();
taskService = processEngine.getTaskService();
identityService = processEngine.getIdentityService();
}
public void deployProcessDefinition(String fileName)
{
....
}
public void startProcessInstance(String processDefinitionName)
{
....
}
public void signalExecution(String executionId)
{
executionService.signalExecutionById( executionId );
}
Once calling those operations in stages, the executionService.signalExecutionById( \
... ) will throw the "a foreign key constraint fails" exception. But my problem is I \
can not find a jBPM API to pass (or fill in) the required information to \
executionService to execute the signalExecutionById(...) if we are doing thing in \
stages.
Thanks a lot for your help and time in advance again.
Tun Mang
