Question

我使用下面的代码连接到JMS。我无法创建连接工厂，因为在PROD环境中，我只是一个消费者，并且不知道它安装了哪个服务器。我有经纪人URL，用户名和密码。

public class HelloWorldProducer implements Runnable {
    public void run() {
        try {
            // Create a ConnectionFactory
            ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory("id972483","octitt123","tcp://ozoi6000:2506");

            // Create a Connection
         Connection connection = connectionFactory.createConnection();

            connection.start();

            // Create a Session
            Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);

            // Create the destination (Topic or Queue)
            Destination destination = session.createQueue("gw.oct.request.letterbusinesscommunication.v1.in.q");

            // Create a MessageProducer from the Session to the Topic or Queue
            MessageProducer producer = session.createProducer(destination);
            producer.setDeliveryMode(DeliveryMode.NON_PERSISTENT);

            // Create a messages
            //String text = "Hello world! From: " + Thread.currentThread().getName() + " : " + this.hashCode();
            TextMessage message = session.createTextMessage(getXMLdata());
            message.setJMSCorrelationID("Sample_JMS_Test");

            // Tell the producer to send the message
            System.out.println("Sent message: "+ message.hashCode() + " : " + Thread.currentThread().getName());
            producer.send(message);

            // Clean up
            session.close();
            connection.close();
        }
        catch (Exception e) {
            System.out.println("Caught: " + e);
            e.printStackTrace();
        }
    }

我收到如下错误：

您尝试连接的端口上配置了什么？尝试将JMS客户端连接到为ActiveMQ JMS客户端所说的OpenWire协议以外的协议提供服务的端口时，您会看到这些类型的错误。

当遇到这样的错误时，通常最好询问代理实际配置的内容
