Answer 2

缺少文件,需要把几个jsf的jar文件考过去

Answer 3

不是j2ee5里不是包含了jsf的jar包了吗？

Answer 4

http://localhost:8080/jsfdemo/jsf.jsp
我输入的路径是这样就暴上面的错误，网上说，不可以直接输入jsp
所是我输入了
http://localhost:8080/jsfdemo/jsf.faces
但又怎么不路径，我给搞疯了。

Answer 5

http://localhost:8080/jsfdemo/index.jsp 
我输入的路径是这样就暴上面的错误，网上说，不可以直接输入jsp 
所是我输入了 
http://localhost:8080/jsfdemo/index.faces 
但又怎么不路径，我给搞疯了。

Answer 6

我遇到问题也是一样，页面文件后缀面是Jsp，在浏览器端输入对应*.faces问题就解决了！

Answer 7

这样改下配置文件就解决了：
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.jsp</url-pattern>
