ClassLoaders.callStaticFunction Java Eclipse的InvocationTargetException

我已经创建了一个程序，通过使用ReverseXSL API将文本转换为xml。

该程序由应用程序通过调用静态方法（ static int transformXSL ）来执行。

我可以通过从Eclipse运行来执行和生成输出。 但是，当我使用应用程序运行程序（jar）时，它卡在某处，我找不到任何东西。

然后，我从Eclipse中的“Debug as …-> Remote Java Application”调试，并在ClassLoaders.callStaticFunction中找到“InvocationTargetException”。

下面的静态方法由应用程序调用。
