}调用这个方法的时候报错：NoClassDefFoundError:MailMessage

如果把MailMessage改为单例的。

则不会报这个错。而是：NoClassDefFoundError:SendMailMessageImpl

如果把SendMailMessageImpl改为单例的。

则不会报这个错。而是：NoClassDefFoundError:SendMessageResult

小弟百思不得其解。

调用receiveJmsMail方法为：

/**
* 邮件消息出jms队列
* @author gouwei
*/
public class QueueComsumerMail extends QueueBase implements MessageListener {
    private static final long serialVersionUID = 1L;
    private static final Logger log = LoggerFactory.getLogger(QueueComsumerMail.class);
    //private MessageDrivenContext mdc;
    private QueueReceiver queueReceiver;
    private JmsCommon jmsCommon = new JmsCommonImpl();
    /**
     * 邮件接收消息
     * @param Message
     */
    public QueueComsumerMail() throws JMSException {
            queueReceiver = queueSession.createReceiver(queueMail);
            queueReceiver.setMessageListener(this);
            queueConnection.start();
    }
    /**
     * 邮件接收消息
     * @param Message
     */
    public void onMessage(Message message) {
        try {
            MapMessage mailContent = (MapMessage)message;
            jmsCommon.receiveJmsMail(mailContent);
        } catch (Exception e) {
            //mdc.setRollbackOnly();
            log.error("接收邮件消息异常!",e);
        }
    }

    public void close() throws JMSException {
        queueReceiver.close();
        queueSession.close();
        queueConnection.close();
    }

有点着急，希望大家帮我分析分析。。谢谢了！
