I am creating EntityManagerFactory object using the below piece of code
EntityManagerFactory emf = Persistence.createEntityManagerFactory("WFJPAPersistenceUnit");
TaskService taskService = new TaskService(emf,SystemEventListenerFactory.getSystemEventListener());
TaskServiceSession taskSession = taskService.createSession();
if (taskServer == null || !taskServer.isRunning()) {
taskServer = new MinaTaskServer(taskService);
Thread thread = new Thread(taskServer);
thread.start();
}
Because of this only, other tables like TASK, Content, I18NText, PeopleAssignement_BAS..etc tables are getting inserted with Task related data.
