问题描述
我正在将Web应用程序上的Mojarra JSF 2.0升级到Mojarra JSF2.1.9的最新稳定版本.页面在Mojarra的早期版本中可以正常加载.但是使用新版本时，在加载包含复合组件的JSF页面时，我会收到以下错误消息.
I am upgrading my Mojarra JSF 2.0 on my web app to the latest stable version of Mojarra JSF2.1.9 . The pages were loading ok with the earlier version of Mojarra. But with the new version I am getting the following error message while loading a JSF page which has got composite components.
/faces/page.xhtml @8,62 Tag Library supports namespace: http://java.sun.com/jsf/composite/components, but no tag was defined for name: webContent
javax.faces.webapp.FacesServlet.service(FacesServlet.java:606)
com.ibm.ws.webcontainer.servlet.ServletWrapper.service(ServletWrapper.java:1657)
com.ibm.ws.webcontainer.servlet.ServletWrapper.service(ServletWrapper.java:1597)
com.ibm.ws.webcontainer.filter.WebAppFilterChain.doFilter(WebAppFilterChain.java:131)
我在Web应用程序中的位置"/资源/组件"处定义了一个复合元素"webContent"，该元素以前用于Mojarra JSF的早期版本.任何线索，为什么我会发生此崩溃.
I have a composite element 'webContent' defined within my web application at the location'/resources/components' and it used to work with the earlier version of Mojarra JSF. Any clue , why am I getting this crash.
推荐答案
我发现了我的真正问题所在，并找到了解决该问题的正确方法:
I have found what my real issue was and the correct soultion to the problem:
我正在使用Webspehere 7服务器，它仅支持"Java Servlet 2.5".从2.1.1开始，所有版本的JSF Mojarra的先决条件都需要"Java Servlet 3.0".
I am using Webspehere 7 server and it suppports only 'Java Servlet 2.5'.The pre-requisite for all versions of JSF Mojarra from 2.1.1 onward need 'Java Servlet 3.0'.
Mojarra 2.0.9是支持"Java Servlet2.5"的最新稳定版本.当我使用Mojarra 2.0.9时，我没有任何问题，一切正常.
Mojarra 2.0.9 is the most recent stable version which supports 'Java Servlet2.5'. When I used Mojarra 2.0.9 , I had no issues, everything worked well.
谢谢，乔
