我想在我的应用程序中使用 Primefaces 和 Myfaces。但是有一个异常(exception)。

这是怎么引起的，我该如何解决？

最佳答案

您的网络应用程序的运行时类路径被多个不同版本的 JAXP 库污染。在您的特定情况下，上述类由不同的类加载器加载(一个通过服务器本身，另一个通过 webapp 本身)，因此不能相互转换。

只需清理并删除类路径中重复的 JAXP 相关库(例如您的特定情况下的 Xalan)。这包括 webapp 的 /WEB-INF/lib 文件夹和服务器的 /lib 文件夹。请注意，一般服务器已经随附了开箱即用的 JAXP。因此，您根本不需要在您的网络应用程序中提供这些内容。

这不是 JSF 特定的问题。
