HI guys, I am new to jbpm. I am using jbpm 5.4 following the jbpm-installer and I am thinking how to integrate the process system into my web application. One step is I wrote below code to query the task list for a user with userId.
The taskservice I used is the default one installed and deployed by the installer: jbpm-human-task-war.war, and I did no change any configuration file after the installation. I can query the task list from the eclipse *Human task view* successfully.  But when I ran below code to query the task list for krisv(I am sure that I can get krisv's task from the Huamn task view), it always failed due to timeout, or just return 0:
import java.util.List;

import org.jbpm.task.AsyncTaskService;
import org.jbpm.task.service.hornetq.AsyncHornetQTaskClient;
import org.jbpm.task.service.responsehandlers.BlockingTaskSummaryResponseHandler;

public class TestTaskClient {

    public static void main(String[] args) {
        AsyncTaskService  client = new AsyncHornetQTaskClient();
        client.connect("", 5153);
        BlockingTaskSummaryResponseHandler taskSummaryHandler = new BlockingTaskSummaryResponseHandler();
        client.getTasksAssignedAsPotentialOwner("krisv", "en-UK", taskSummaryHandler);
       // I also tried client.getTasksAssignedAsPotentialOwner("krisv", null, taskSummaryHandler); but still failed;
        List tasks = taskSummaryHandler.getResults();

Anyone tell me why? Thanks in advance.
