Gao jie [http://community.jboss.org/people/super_man.sh] created the discussion "About jBPM5.1 ProcessInstance and HumanTask persisit" To view the discussion, visit: http://community.jboss.org/message/630762#630762 -------------------------------------------------------------- Dear All, I'm use MySQL for persist ProcessInstance and ProcessInstance and HumanTask Object.This is the code: public static final void main(String[] args) {      TaskClient taskClient = new TaskClient(new MinaTaskClientConnectorExt("MinaConnector",                new MinaTaskClientHandler(SystemEventListenerFactory.getSystemEventListener())));      taskClient.connect("127.0.0.1", 9123);      //init datasource.......      KnowledgeBase kbase = readKnowledgeBase();                     EntityManagerFactory emf =Persistence.createEntityManagerFactory("org.jbpm.jpa" );      Environment env = KnowledgeBaseFactory.newEnvironment();      env.set( EnvironmentName.ENTITY_MANAGER_FACTORY, emf );      env.set(EnvironmentName.TRANSACTION_MANAGER, TransactionManagerServices.getTransactionManager());      // create a new knowledge session that uses JPA to store the runtime state            StatefulKnowledgeSession ksession = JPAKnowledgeService.newStatefulKnowledgeSession(kbase, null, env );      //StatefulKnowledgeSession ksession = JPAKnowledgeService.loadStatefulKnowledgeSession(1, kbase, null, env);      //StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();               WSHumanTaskHandler taskHandler=new WSHumanTaskHandler();         taskHandler.setClient(taskClient);         ksession.getWorkItemManager().registerWorkItemHandler("Human Task", taskHandler);         Map params = new HashMap();         params.put("userId", "krisv");         params.put("description", "Need a new laptop computer");         ksession.startProcess("com.sample.humantask", params);        ksession.dispose();      taskClient.disconnect(); }   This main methd execute is ok,then I found ProcessInstance and Human info is in MySQL(in sessioninfo and task tables).Next,I write complete the task code as below: public static final void main(String[] args) {           TaskClient taskClient = new TaskClient(new MinaTaskClientConnectorExt("MinaConnector",                     new MinaTaskClientHandler(SystemEventListenerFactory.getSystemEventListener())));           taskClient.connect("127.0.0.1", 9123);               //init datasource......             KnowledgeBase kbase = readKnowledgeBase();           EntityManagerFactory emf =Persistence.createEntityManagerFactory("org.jbpm.jpa" );           Environment env = KnowledgeBaseFactory.newEnvironment();           env.set( EnvironmentName.ENTITY_MANAGER_FACTORY, emf );           env.set(EnvironmentName.TRANSACTION_MANAGER, TransactionManagerServices.getTransactionManager());           // create a new knowledge session that uses JPA to store the runtime state             StatefulKnowledgeSession ksession = JPAKnowledgeService.loadStatefulKnowledgeSession(1, kbase, null, env);           BlockingTaskSummaryResponseHandler taskSummaryHandler = new BlockingTaskSummaryResponseHandler();           List<String> groups = new ArrayList<String>();           groups.add("sales");           taskClient.getTasksAssignedAsPotentialOwner("sales-rep", groups, "en-UK", taskSummaryHandler);           TaskSummary task1 = taskSummaryHandler.getResults().get(0);           BlockingTaskOperationResponseHandler taskOperationHandler = new BlockingTaskOperationResponseHandler();           taskClient.claim(task1.getId(), "sales-rep", groups, taskOperationHandler);           taskOperationHandler = new BlockingTaskOperationResponseHandler();           taskClient.start(task1.getId(), "sales-rep", taskOperationHandler);           taskOperationHandler.waitTillDone(1000);           taskOperationHandler = new BlockingTaskOperationResponseHandler();           Map<String, Object> results = new HashMap<String, Object>();           results.put("comment", "Agreed, existing laptop needs replacing");           results.put("outcome", "Accept");           ContentData contentData = new ContentData();           contentData.setAccessType(AccessType.Inline);           ByteArrayOutputStream bos = new ByteArrayOutputStream();           ObjectOutputStream out;           try {                     out = new ObjectOutputStream(bos);                     out.writeObject(results);                     out.close();                     contentData = new ContentData();                     contentData.setContent(bos.toByteArray());                     contentData.setAccessType(AccessType.Inline);           } catch (IOException e) {                     e.printStackTrace();           }           taskClient.complete(task1.getId(), "sales-rep", contentData, taskOperationHandler);           taskOperationHandler.waitTillDone(1000);           ksession.signalEvent("Signal",null);           ksession.dispose();           taskClient.disconnect(); }   Execute the code,The task will be completed. I want to the ProcessInstance Continue to flow after task complete.So I write | | ksession.signalEvent("Signal",null); | But the processInstance not continue to flow, Please help me! -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/630762#630762] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
