严重：SAAJ0540:运行Java小程序后出错

我正在尝试将一个小程序运行到.Net Web项目中，我将一个jar导入到项目中，其中包含我用Eclipse开发的所有小程序，在运行小程序之前一切正常，当我运行它时，我出现了一个错误，我不知道如何解决它。错误如下：

我有这部分代码的代码是：

在.Net中运行小程序时，我也使用了xercesImpl.jar和xml-api.jar，那么这里有什么问题呢？。我有点迷路了

非常感谢和问候

以下是您需要采取的几个步骤：

将您的enviar_y_obtener_字符串执行包装在匿名特权中 通过调用AccessController.doPrivilegedyourPrivilegedAction检索字符串 此外，您还需要考虑：

为小程序签名 使用Java代码约定仅用英语编写代码、方法等。

如何使用Keytool对小程序进行签名？。Thanks@zoit您可以参考有关如何为小程序签名的链接。执行后：将enviar_y_obtener_字符串执行包装在匿名PrivilegedAction中，通过调用AccessController.doPrivilegedyourPrivilegedAction检索该字符串我会收到与以前相同的错误。
