我有一个使用 mojarra 2.1.17 发行版开发的 JSF 2.1 Web 应用程序,它在 JBoss 6.1 容器上运行时遇到任何问题:现在我必须更改应用程序服务器,我必须使用随 MyFaces JSF 2 发行版诞生的 websphere AS 8.5。我正在尝试部署和启动我的 webapp 忽略 MyFaces 并使用 Mojarra,将我的 EAR 配置为 IBM 官方指南所示,配置包含 mojarra dist 的共享库,将其链接到专门为我的 server1 WAS 8.5 实例创建的新类加载器。它根本不起作用,当我部署我的 web 应用程序时,当 WAS 尝试启动应用程序时,我得到了这个堆栈跟踪:

我也调试了 mojarra dist 的 cleanupInitMaps() 方法,我看到它试图从 FacesContext 中获取两个 Map 类型的变量,称为threadInitContext和initContextServletContext但得到 null:
Field threadMap = FacesContext.class.getDeclaredField("threadInitContext");
and
Field initContextMap = FacesContext.class.getDeclaredField("initContextServletContext");
这是如何引起的,我该如何解决?
