| i came up with some problems again...
| i would like to run a persistent execution mode test...
| i worked quite well when deploy, start a new process instance with a process definition,
| but when i resume a persisted process instance, something i don't know what to do happened..
|
| my source code & jvm stack:
|
| public class PersistentExecutionModeTest extends EnvironmentFactoryTestCase {
|
| SessionFactory sessionFactory;
| Session session;
| Transaction transaction;
|
| 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
|
| }
|
| }
|
| here is problems:
| Hibernate:
| /* delete org.jbpm.pvm.internal.model.ExecutionImpl */ delete
| from
| JBPM_EXECUTION
| where
| DBID_=?
| and DBVERSION_=?

| BY THE WAY,
| at this line: Execution execution = executionService.signalExecutionById("test/request17", "end");
| as referenced in the previous version manual, here should be call the method with the parameters ("test:1/request17", "end")?
| but i got exception as nothing found, and i trace the source code to DefaultIdGenerator#createId
| ....
| if (parent!=null) {
| base = parent.getId();
| } else if (processDefinition.getKey()!=null){ // processDefinition.getKey() = "test"
| base = processDefinition.getKey();
| } else {
| base = processDefinition.getId();
| }
| ....
| is there anything wrong with my process definition? or because of my wrongful use of the API?
|
