Я использую тебя follwoing фрагмент кода:

KnowledgeBase kbase = readKnowledgeBase(); 
    StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession(); 
    GenericHTWorkItemHandler htHandler = createTaskHandler(ksession); 
    ksession.getWorkItemManager().registerWorkItemHandler("Human Task",htHandler); 

    Map<String, Object> params = new HashMap<String, Object>(); 
    params.put("employee", "ABC"); 
    ksession.startProcess("com.sample.bpmn.hello", params); 
    System.out.println("Process started ..."); 


//Creates a local task service and attaches it to a human task handler 
    public GenericHTWorkItemHandler createTaskHandler(StatefulKnowledgeSession ksession) { 
     TaskService ts = new TaskService(Persistence.createEntityManagerFactory("org.jbpm.task"), 
       SystemEventListenerFactory.getSystemEventListener()); 
     LocalTaskService taskService = new LocalTaskService(ts); 
     LocalHTWorkItemHandler taskHandler = new LocalHTWorkItemHandler(taskService, ksession); 
//  taskHandler.connect(); 
     this.service = taskService; 
     return taskHandler; 
    } 

я использовал происходит некорректно баночки (прилагается скриншот):

Получаем эту ошибку в строке startProcess. Пожалуйста, помогите мне решить эту проблему.

Answer 1

Кажется, вы используете несоответствие версий jBPM и Drools. Какую версию jBPM вы используете? Предполагая, что вы используете jBPM 5.4, вы должны использовать Drools 5.5 jars.
