Jsf 当使用Facelets 404错误页面时，Websphere抛出FileNotFoundException，而不是调度到404错误页面

我正在尝试将Facelets页面定义为my web.xml中的自定义404错误页面，如下所示：

<?xml version="1.0" encoding="UTF-8"?>

<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
         version="3.0">
...
 <welcome-file-list>
        <welcome-file>/index.xhtml</welcome-file>
    </welcome-file-list>
<error-page>
      <error-code>404</error-code>
      <location>/pageNotFound.xhtml</location>
</error-page>
<servlet>
    <servlet-name>Faces Servlet</servlet-name>
    <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.xhtml</url-pattern>
</servlet-mapping>
...
</web-app>

在我以前的项目中，我们使用了WildFly 8.2.0.final服务器，这在我的项目中起到了作用。当我尝试使用JSP而不是Facelets页面时，它确实可以工作

在Websphere liberty profile 8.5.5.4中是否可以使用Facelets页面作为自定义错误页面？我需要在Websphere上进行更多配置吗？或者我在这里遗漏了什么？

所以你要求abc而没有分机？当您尝试使用扩展时会发生什么情况？当我转到abc.xhtml时，它会被发送到正确的页面。但是我在日志中也看到了一个错误：

应用程序类'org.apache.myfaces.shared_impl.context.flash.FlashImpl.isKeepMessages:392'java.lang.NullPointerException

。看起来您的容器和myfaces发行版有缺陷：错误页面阀无法捕获伪造的URL，因为它缺少扩展指向一个容器bug；MyFaces异常显然是flashscope实现中的一个bug
