Answer 1

據抱怨缺少類文件。那個文件應該在哪裏取決於你。

Answer 2

爲了識別在堆棧跟蹤的錯誤的原因，通常從底部讀出的棧最多並尋找由話引起的。這是你的問題的主要原因。在你的特定情況下：

Caused by: java.lang.ClassNotFoundException: com.ibm.mq.headers.MQDataException 

因此，說明你的類路徑中找不到這個類MQDataException。所以你應該把包含這個類的jar包放在你的應用程序的classpath中，它應該可以正常工作。

Answer 3

如果它是獨立應用程序，只需在所選位置安裝WebSphere MQ客戶機，並將幾個jar添加到類路徑，如下所示：http://publib.boulder.ibm.com/infocenter/wmqv7/v7r0/index.jsp?topic=%2Fcom.ibm.mq.csqzaw.doc%2Fjm10330_.htm。我猜這會更容易。
