To invoke a method Expression

[abhilashs]

Hi,

I am trying to invoke a method Expression. But I am not able to call the method from the Delegate. And its giving : org.activiti.engine.ActivitiIllegalArgumentException: Field definition uses unexisting field 'testService' on class com.activiti.test.bpm.WebserviceTask

I need to know how exactly the method is invoked from the Service Task using the Expression? Should the method be in same Service Task or elsewhere?

Expression configured in BPMN:
  <serviceTask id="webService_task_id" name="WebService Task" activiti:class="com.activiti.test.bpm.WebserviceTask">
      <extensionElements>
        <activiti:field name="testService">
          <activiti:expression><![CDATA[testService.testMethod()]]></activiti:expression>
        </activiti:field>
      </extensionElements>
    </serviceTask>

Thanks
Abhilash S

Hi Abhilash,

ReflectionUtils did not find any field with the name testService in the class WebserviceTask. That's the cause of the error.
Can you create jUnit test?
