如何确定此错误堆栈的原因

是否抱怨丢失Jar文件？

Answer 1

为了识别StackTrace中错误的原因，通常从底部向上读取堆栈并查找由引起的单词。这是你问题的主要原因。在您的特定情况下：

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

因此声明在类路径中找不到此类MQDataException。所以你应该把包含这个类的jar放在应用程序的类路径上，它应该可以正常工作。

Answer 2

抱怨缺少类文件。该文件应该由您决定。

Answer 3

如果它是一个独立的应用程序，只需在您选择的位置安装WebSphere MQ Client，并将几个jar添加到类路径中，如下所示：http://publib.boulder.ibm.com/infocenter/wmqv7/v7r0/index.jsp?topic=%2Fcom.ibm.mq.csqzaw.doc%2Fjm10330_.htm。我想这会更容易。
