问题描述
我有一个使用 Sun Java Studio Creator 构建的 JSF 1.1 应用程序的战争，该应用程序在 iPlanet 上运行，我必须在 WAS (WebSphere Application Server) 8.5.5 上运行。由于无限递归，它无法显示欢迎页面。对 SO 上类似问题的回答指出，应删除战争中捆绑的 JSF 库，以防止与 WAS 中的 JSF 运行时发生冲突，但在这种情况下没有帮助。下面是堆栈跟踪

解决方法
WebSphere 8.5.x 附带的 JSF 实现是 MyFaces，版本是 2.0。
您需要使用 SunRI 作为 JSF 版本才能在您的应用程序中支持 JSF 1.1。
请注意，这会影响整个应用服务器，而不仅仅是您为其配置的应用程序。
