Websphere 8.5.5.1 JSF 2.2 @MultipartConfig答案

【问题描述】：

我正在尝试在 Websphere 8.5 中启动并运行 Mojarra 2.2.6（或 MyFaces 2.2.2，两者都有相同的例外）。我已经像往常一样将类加载器设置正确地设置为 PARENT_LAST 和 SINGLE。新的 jar 被成功拾取，但引发了以下讨厌的异常并导致应用程序无法启动。任何帮助表示赞赏，谢谢！

An exception occurred while validating an annotation: com.ibm.wsspi.amm.validate.ValidationException: SRVE8016E: The @MultipartConfig annotation can not be applied to the class, javax.faces.webapp.FacesServlet, because it extends the wrong super class

【问题讨论】：

可能是stackoverflow.com/questions/18544763/websphere-7-with-jsf-2的重复问题
升级到 2.2 与提到的方案不同。我相信这与 WAS 中的 OpenWebBeans 版本有关。我们将与 IBM 建立 PMR。

【解决方案1】：

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Websphere Bug，更新到8.5.5.6修复了。

【解决方案2】：

我写这篇博客是为了演示如何让 websphere 8.5 使用 mojarra 而不是 myfaces。

【解决方案3】：

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 和 jsf-impl jars）并将它们添加到一个隔离的共享库中解决了这个问题。此外，我还需要在隔离的共享库中添加 primefaces jar（我使用 PF 4.0）以消除错误。
