    persistent execution mode

    jeffery c Newbie

      can anyone give me a persistent execution mode program demo?
      i have been stucked..

      my testcase and exception jvm method call stack as follow:

      public class PersistentExecutionModeTest extends EnvironmentFactoryTestCase {
      
       public void testDeploy() { // seems ok
      // /*
       JbpmConfiguration environmentFactory = (JbpmConfiguration)getEnvironmentFactory();
       ProcessService processService = environmentFactory.get(ProcessService.class);
      
       ClientProcessDefinition processDefinition = ProcessDefinitionBuilder
       .startProcess("test")
      
       .startActivity("start", WaitState.class)
       .initial()
       .flow("end","end")
       .endActivity()
      
       .startActivity("end", AutomaticActivity.class)
       .endActivity()
      
       .endProcess();
      
       Deployment deployment = new DeploymentImpl();
       deployment.addObject("testProcesssss", processDefinition);
      
       ((ProcessServiceImpl) processService).deploy(deployment);
      // */
       }
      
       public void testStartProcessInstance() { // seems ok, 2
      
       JbpmConfiguration environmentFactory = (JbpmConfiguration) getEnvironmentFactory();
       ExecutionService executionService = environmentFactory.get(ExecutionService.class);
       Execution execution = executionService.startProcessInstanceById("test:1", "request17");
       }
      
       public void testResumeProcessInstance(){ // something wrong...
       JbpmConfiguration environmentFactory = (JbpmConfiguration)getEnvironmentFactory();
       ExecutionService executionService = environmentFactory.get(ExecutionService.class);
       Execution execution = executionService.signalExecutionById("test/request17", "end"); // exception occured here
      
       }
      
      }
