Java MQSampleMessageManager无法解析为类型

我希望您能帮助我解决编译示例程序MQIVP时遇到的问题。将WebSphere MQ client for 7.1.0.6下载到我的windows 7 PC并添加外部jar引用后，我发现以下错误：

无法将MQSampleMessageManager messageMgr解析为类型

private MQSampleMessageManager messageMgr;
private String hostname;
private String channel = null;
private String queueMgr;
private MQQueueManager queueManager;
private String port = "-1"; // @L1C
private Hashtable properties = null; // @L1A
// An output stream writer to convert the characters to.......

我正在使用mqv8002

MQSampleManager类与MQIVP驻留在同一目录中。您需要设置类路径。我在编译时遇到以下错误

    MQIVP.java:46: error: cannot find symbol
      private MQSampleMessageManager messageMgr;
              ^
      symbol:   class MQSampleMessageManager
      location: class MQIVP
    MQIVP.java:94: error: cannot find symbol
        messageMgr = new MQSampleMessageManager("mqjcivp");

                     ^
  symbol:   class MQSampleMessageManager
  location: class MQIVP
2 errors

设置类路径解决了以下问题：

CLASSPATH=%CLASSPATH%;C:\Program Files\IBM\WebSphere MQ\Tools\wmqjav\samples\MQSampleMessageManager.class
