Question

我创建了一个队列管理器，队列，通道（服务器连接）。当我尝试发送消息时，看到此错误： com.ibm.msg.client.jms.DetailedIllegalStateException：JMSWMQ0018：无法以连接模式“客户端”和主机名“ epspa（1401）”连接到队列管理器“ MY_LOCAL_QM”。检查队列管理器是否已启动，如果在客户端模式下运行，请检查是否正在运行侦听器。有关更多信息，请参见链接的异常。

也许我需要将用户设置为队列管理器？因为我使用相同的Java代码，但是尝试连接到另一个队列管理器，所以效果很好。但这不适用于我的队列管理器。 IBM MQ已安装在另一台PC上。

 private static final String HOST = "epspa";
private static final int PORT = 1401;
private static final String CHANNEL = "API.SVRCONN_LOCAL";
private static final String QMN = "MY_LOCAL_QM";
private static final String QUEUE_NAME = "API.QUEUE_NAME";
private static final String message ="message";

public static String sendMessage(String message) {
    String result = "Error";
    try {
        MQQueueConnectionFactory cf = new MQQueueConnectionFactory();
        cf.setHostName(HOST);
        cf.setChannel(CHANNEL);
        cf.setPort(PORT);
        cf.setQueueManager(QMN);
        cf.setTransportType(WMQConstants.WMQ_MESSAGE_BODY_MQ);

        Destination destination = null;
        MessageProducer producer = null;

        Connection c = cf.createConnection();
        Session s = c.createSession(false, Session.AUTO_ACKNOWLEDGE);
        destination = s.createQueue(QUEUE_NAME);
        producer = s.createProducer(destination);
        TextMessage tmo = s.createTextMessage();


        ((MQDestination) destination).setMessageBodyStyle
                (WMQConstants.WMQ_MESSAGE_BODY_MQ);

        tmo.setIntProperty(WMQConstants.JMS_IBM_CHARACTER_SET, 1208);
        tmo.setIntProperty(WMQConstants.JMS_IBM_ENCODING,546);
        tmo.setText(message);
        producer.send(tmo);

        result = "Success!";
    } catch (JMSException e) {
        e.printStackTrace();
    } catch (Exception e) {
        e.printStackTrace();
    }
    return result;
}

Answer 1

cf.setTransportType（WMQConstants.WMQ_MESSAGE_BODY_MQ）;

嗯，那是不正确的。应该是：

cf.setTransportType(WMQConstants.WMQ_CM_CLIENT);

JMSWMQ0018：无法连接到队列管理器

JMS错误没有提供有关MQ正在抱怨的足够详细信息。您需要输出LinkedException。

catch (JMSException e)
{
   if (e != null)
   {
      System.err.println("getLinkedException()=" + e.getLinkedException());
      System.err.println(e.getLocalizedMessage());
      e.printStackTrace();
   }
}

您确定1401端口正确吗？ MQ的默认端口号是1414。针对您的队列管理器启动runmqsc。即

runmqsc MY_LOCAL_QM

然后发出以下命令：

DIS LISTENER(LISTENER.TCP)

PORT属性赋予什么值？

tmo.setIntProperty（WMQConstants.JMS_IBM_CHARACTER_SET，1208）; tmo.setIntProperty（WMQConstants.JMS_IBM_ENCODING，546）;

为什么要设置CCSID和编码？您为什么不让JMS＆MQ处理呢？

这是一个功能齐全的JMS程序，它将消息放入队列：
