Activiti Workflow Engine: Deployment Not Successful

Question

currently I am working with activity workflow engine and XML to develop business process diagram. FYI, the activiti workflow diagram is running above Tomcat server.

But i don't know why, I always fail to deploy my process. Here is my XML code:

<definitions id="definitions"
  targetNamespace="http://activiti.org/bpmn20" 
  xmlns:activiti="http://activiti.org/bpmn"
  xmlns="http://www.omg.org/spec/BPMN/20100524/MODEL">

        <process id="accidentForm" name="accidentFormProcess">

          <startEvent id="startEvent" />

          <sequenceFlow id='flow1' sourceRef='startEvent' targetRef='submitForm' />

          <userTask id="submitForm" name="Submit Accident Form" >

            </potentialOwner>
          </userTask>

          <sequenceFlow id='flow11' sourceRef='claimAccident' targetRef='endProcess' />

          <endEvent id="endProcess" />

         </process>
</definitions>

Is there anything wrong with my XML? And is there any way to do debugging. For example by using some log or error console? Thanks in advance

Answer 1

• Firstly there are multiple userTask with ID value 'sendBoss'. Probably to be called 'sendEmploye'.
• There is no ID/IDREF binding for IDREF 'reviewForm' in sequence flow 'flow7'.
• There is no message definition referenced in intermediate event 'parallelTask'.

TIP: You can use activiti designer plugin for eclipse. http://docs.alfresco.com/4.2/index.jsp?topic=%2Fcom.alfresco.enterprise.doc%2Ftasks%2Fwf-install-activiti-designer.html

Configure logger in activiti. http://activiti.org/userguide/index.html#loggingConfiguration

Answer 2

The Best way is to use Activiti Designer Plug-ins in Eclipse. Make use of Maven for activiti dependency. Must try it works. And, for deployment use of "Repository Service" is Must. It is one of the API services provided by the process Engine of Activiti.
