Question

我使用spring jms连接到Websphere MQ。

Connection names (all as an example): hostname: <Websphere ip address> http://localhost:9043
given hostname 12.123.0.12

In Resources->JMS->Queue connection Factories
name: MQDemo
JNDI name: MQDemo

2 Queues:
name: MQ.T11.UPDATE.REQUEST
JNDI name: jms/MQ.T11.UPDATE.REQUEST

name: MQ.T11.INQUIRY.REPLY
JNDI name: jms/MQ.T11.UPDATE.REQUEST

DemoMain.java

主要方法：

ApplicationContext ctx = new ClassPathXmlApplicationContext("app-context.xml");
    // get bean from context
    JmsMessageSender jmsMessageSender = (JmsMessageSender)ctx.getBean("jmsMessageSender");
    // send to default destination 
         jmsMessageSender.send();

JMSMessageSender.java

package name: com.java.geek

 @Autowired
  private JmsTemplate jmsTemplate;


  /**
   * send text to default destination
   * @param text
   */
  @Cacheable("message")
  public void send() {
      System.out.println("in send");
        jmsTemplate.send(new MessageCreator() {
        @Override
        public Message createMessage(Session session)throws JMSException {

            System.out.println("in create message");
        Message message = (Message) session.createTextMessage("Hello JMS");
        return message;
        }
        });

    }

  public JmsTemplate getJmsTemplate()
  {
      return jmsTemplate;
  }

  public void setJmsTemplate(JmsTemplate jmsTemplate)
  {
      this.jmsTemplate = jmsTemplate;
  }

APP-context.xml中

我收到了错误，

和另一个错误SAXException。

我无法连接到Websphere MQ。请建议代码中的错误在哪里。

Answer 1

NoClassDefFoundError表明编译器能够找到类，但运行时进程不是。

我建议您的运行时类路径中可能缺少某些内容。尝试将它与构建/编译类路径进行比较。

Answer 2

我说你需要检查代码运行的盒子上是否正确安装了MQ Client。复制WMQ jar并期望它能够正常工作是一个常见的错误。您的代码将构建，但您将从MQ类中获得这种类型的NoClassDefFound。虽然您最终可以在工作的IBM安装中追逐每个jar，但它不受支持（参见http://www-01.ibm.com/support/docview.wss?uid=swg21376217）

获取WMQ安装媒体并在您使用的计算机上运行安装。然后运行IBM的＃34;入门＆＃34;确保它可以运作。
