Hi ! could you help me for some questions ?
How can i get the task id when started a process

in my project i use  this code to do the job.



package com.sample;


import java.util.HashMap;
import java.util.Map;


import org.drools.KnowledgeBase;
import org.drools.builder.KnowledgeBuilder;
import org.drools.builder.KnowledgeBuilderFactory;
import org.drools.builder.ResourceType;

import org.jbpm.task.service.responsehandlers.BlockingTaskSummaryResponseHandler;


/**
* This is a sample file to launch a process.
*/
public class ProcessTest {


          public static final void main(String[] args) {
                    try {
                              // load up the knowledge base
                              KnowledgeBase kbase = readKnowledgeBase();
                              StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();
                              HornetQHTWorkItemHandler sHumanTaskHandler = new HornetQHTWorkItemHandler(ksession);
                              ksession.getWorkItemManager().registerWorkItemHandler("Human Task",
                                                  sHumanTaskHandler);
                              SyncTaskServiceWrapper sTaskService = new SyncTaskServiceWrapper(new AsyncHornetQTaskClient(
                                                  "HumanTaskExample-testClient"));
                              sTaskService = new SyncTaskServiceWrapper(new AsyncHornetQTaskClient(
                                                  "HumanTaskExample-testClient"));
                              sTaskService.connect("127.0.0.1", 5445);
                              KnowledgeRuntimeLogger logger = KnowledgeRuntimeLoggerFactory.newThreadedFileLogger(ksession, "test", 1000);
                              // start a new process instance
                              BlockingTaskSummaryResponseHandler taskSummaryResponseHandler =
                                                  new BlockingTaskSummaryResponseHandler();
                              BlockingTaskOperationResponseHandler responseHandler =
                                                  new BlockingTaskOperationResponseHandler();
                              BlockingGetTaskResponseHandler getTaskResponseHandler = new BlockingGetTaskResponseHandler();
                              Map<String, Object> params = new HashMap<String, Object>();
                              params.put("employee", "111");
                              params.put("reason", "Yearly performance evaluation");
                              ksession.startProcess("com.sample.evaluation", params);
                              System.out.println("Process started ...");
                              logger.close();
                    } catch (Throwable t) {
                              t.printStackTrace();
                    }
          }


          private static KnowledgeBase readKnowledgeBase() throws Exception {
                    KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
                    kbuilder.add(ResourceFactory.newClassPathResource("Evaluation.bpmn"), ResourceType.BPMN2);
                    return kbuilder.newKnowledgeBase();
          }


}



when i user the ksession.startProcess("com.sample.evaluation", params); to start a process, the task is persisted in the DB , for this ,i also want to get the task id ,but these nothing return to get it.
how can i do ?
