Get the node name of a task

prap89 — Thu, 04 Aug 2011 15:49:18 GMT

Hello folks,I am new to Activiti and I currently building a sample application that needs me to get the service task id and its name from its properties as the process runs in the workflow. Currently I just want to print the service task name and its id. I looked in the forums and it seems you need

Hi prap89,

Try to do this inside your delegate

ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
RuntimeService runtimeService = processEngine.getRuntimeService();

Than, you can find whatever you want with the process.

// you must call this code before the workflow reach your delegate.
ProcessEngines.init();

Best regards,

Franklin

i tried it but it does not work. I get exception

What I did was:
1. Created service task and bind it with a class that implements Java Delegate
2. Followed the procedure you mentioned.

My service handler code:


public class ServiceHandle implements JavaDelegate {

 @Override
 public void execute(DelegateExecution execution) throws Exception {
  
  ProcessEngine processEngine =  ProcessEngines.getDefaultProcessEngine();
  RuntimeService runtimeService = processEngine.getRuntimeService();

  System.out.println("Event Name 1: "+ runtimeService.getActiveActivityIds(execution.getId()));
 }
}

Calling the services from within a java delegate is not going to work (it might, sometimes, but then thats pure luck).

Check the operations available on the execution object.

Re: Get the node name of a task

prap89 — Fri, 05 Aug 2011 17:36:48 GMT

execution object does not have anything related to taskname or taskid.
Can you throw some light on it?

Instead of using the JavaDelegate, switch to the ActivityBehavior approach.

There, you get an ActivitiExecution, on which you can call getActivity().
