java-ee – HornetQ：如何重用XAConnection和XASession

我在尝试在JBoss应用程序中的多个worker上重用XAConnection和XASession时遇到了一些问题.我已经设法将问题简化为一种方法.它应该能够使用相同的连接和会话生成和消费者消息.目前,我的应用程序有很多队列和工作人员,每个工作人员当前正在启动并启动每个自己的连接和会话,而不是共享它.应该不可能吗？

这是我的代码示例：

import org.apache.log4j.Logger;
import javax.annotation.PostConstruct;
import javax.annotation.PreDestroy;
import javax.ejb.Singleton;
import javax.ejb.Startup;
import javax.jms.*;
import javax.jms.Queue;
import javax.naming.InitialContext;

@Singleton
@Startup
public class QueueTest {

    private Logger logger = Logger.getLogger(QueueTest.class);

    @PostConstruct
    public void startup() {
        try {
            String queue = "queue/Queue1";
            String message = "test";

            //setting up connection
            InitialContext iniCtx = new InitialContext();
            XAConnectionFactory qcf = (XAConnectionFactory) iniCtx.lookup("java:/JmsXA");
            XAConnection connection = qcf.createXAConnection();
            connection.start();
            logger.debug("creating connection at " + new java.util.Date());

            //setting up session
            XASession session = connection.createXASession();
            logger.debug("creating session at " + new java.util.Date());

            //find the queue
            Object queueObj = iniCtx.lookup(queue);
            Queue jmsQueue = (javax.jms.Queue)queueObj;

            //adding message to queue
            javax.jms.MessageProducer producer = session.createProducer(jmsQueue);
            javax.jms.TextMessage textMessage = session.createTextMessage(message);
            producer.send(textMessage);
            producer.close();
            logger.debug("Message added to queue");

            //receiving message from queue
            javax.jms.MessageConsumer consumer = session.createConsumer(jmsQueue);
            javax.jms.TextMessage messageReceived = (javax.jms.TextMessage)consumer.receive(5000);

            if (messageReceived==null)
                throw new Exception("No message reveived");

            logger.debug("Got message:"+messageReceived.getText());
            consumer.close();
        }
        catch(Exception e) {
            logger.debug("Error: " + e.getMessage(),e);
        }
    }

    @PreDestroy
    public void shutdown() {

    }
}

它导致此输出：

11:47:17,905 DEBUG [QueueTest] (MSC service thread 1-8) creating connection at Thu Sep 05 11:47:17 CEST 2013
11:47:18,041 DEBUG [QueueTest] (MSC service thread 1-8) creating session at Thu Sep 05 11:47:18 CEST 2013
11:47:18,065 DEBUG [QueueTest] (MSC service thread 1-8) Message added to queue
11:47:23,081 DEBUG [QueueTest] (MSC service thread 1-8) Error: No message reveived

如您所见,消费者未收到任何消息.为什么？

编辑1：

package dk.energimidt.uapi.zigbee.services;

import org.apache.log4j.Logger;

import javax.ejb.Stateless;
import javax.ejb.TransactionAttribute;
import javax.ejb.TransactionAttributeType;
import javax.jms.Queue;

@TransactionAttribute(TransactionAttributeType.REQUIRED)
@Stateless
public class QueueTestWorkerBean implements QueueTestWorker {

    private Logger logger = Logger.getLogger(QueueTestWorkerBean.class);

    public void run() {
        try {
            String queue = "queue/Queue1";
            String message = "test";

            //setting up connection
            InitialContext iniCtx = new InitialContext();
            XAConnectionFactory qcf = (XAConnectionFactory) iniCtx.lookup("java:/JmsXA");
            XAConnection connection = qcf.createXAConnection();
            connection.start();
            logger.debug("creating connection at " + new java.util.Date());

            //setting up session
            XASession session = connection.createXASession();
            logger.debug("creating session at " + new java.util.Date());

            //find the queue
            Object queueObj = iniCtx.lookup(queue);
            Queue jmsQueue = (javax.jms.Queue)queueObj;

            //adding message to queue
            javax.jms.MessageProducer producer = session.createProducer(jmsQueue);
            javax.jms.TextMessage textMessage = session.createTextMessage(message);
            producer.send(textMessage);
            producer.close();
            session.commit();
            logger.debug("Message added to queue");

            //receiving message from queue
            javax.jms.MessageConsumer consumer = session.createConsumer(jmsQueue);
            javax.jms.TextMessage messageReceived = (javax.jms.TextMessage)consumer.receive(5000);

            if (messageReceived==null)
                throw new Exception("No message reveived");

            logger.debug("Got message:"+messageReceived.getText());
            consumer.close();

            connection.close();
        }
        catch(Exception e) {
            logger.debug("Error: " + e.getMessage(),e);
        }
    }
}

现在我在Session.Commit()上得到一个例外：
