jsf-2 – Websphere 8.5 – JSF webapp context init错误：cleanupInitMaps

我有一个用mojarra 2.1.17开发的JSF 2.1 Web应用程序,它运行在JBoss 6.1容器上的任何问题：现在我必须更改应用程序服务器,我必须使用与MyFaces JSF 2分配一起出生的websphere AS 8.5.我正在尝试部署并启动我的webapp忽略MyFaces并使用Mojarra,在IBM官方指南中配置我的EAR,配置包含mojarra dist的共享库,将其链接到专为我的WAS 8.5的server1实例创建的新类加载器.它根本不起作用,当我部署我的webapp时,我在WAS尝试启动应用程序时得到这个堆栈跟踪：

我也调试了mojarra dist的cleanupInitMaps()方法,我看到它试图从FacesContext中获取两个名为threadInitContext和initContextServletContext的变量Map,但是得到null：

Field threadMap = FacesContext.class.getDeclaredField("threadInitContext");
and 
Field initContextMap = FacesContext.class.getDeclaredField("initContextServletContext");

这是怎么造成的,我该如何解决？

最佳答案 好的,我解决了!!

首先,我将我的服务器实例的类加载器设置为PARENT_LAST restart.然后我按照以下步骤操作：

1)将Mojarra lib放入简单的共享库中;

2)使用jsf web模块部署ear,在从控制台启动应用程序之前,我将共享lib链接到它和内部的所有模块;

3)我将应用程序类加载器设置为PARENT_LAST;

4)启动应用程序,它的工作原理！

就这样 ！！
