我正在尝试在 Websphere 8.5 中启动并运行 Mojarra 2.2.6（或 MyFaces 2.2.2，两者上的相同例外）。我已经像往常一样将类加载器设置正确设置为 PARENT_LAST 和 SINGLE。新 jar 正在成功拾取，但抛出以下讨厌的异常并导致应用程序无法启动。任何帮助不胜感激，谢谢！

我在使用 WAS 8.0.0.8 时遇到了同样的问题。 我通过从我的 Web 应用程序中删除 Mojarra jars （jsf-api & jsf-impl jars） 并将它们添加到隔离的共享库中来解决此问题。此外，我需要在隔离的共享库中添加素数 jar（我使用了 PF 4.0），以使错误消失。
错误
SRVE8016E: The @MultipartConfig annotation can not be applied to the class, javax.faces.webapp.FacesServlet, because it extends the wrong super class
是一个 Websphere 错误，更新到 8.5.5.6 可以修复它。
我写这篇博客是为了演示如何让 websphere 8.5 使用 mojarra 而不是 myfaces。
