jsf初学者遇到问题，求助

自己想搭建一个jsf开发环境，但是搭建好以后jsf或者primefaces的控件都不现实，相关配置如下：
web.xml



<?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" version="2.5" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee   http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

    </context-param>

    

    <listener>

        <listener-class>

            com.sun.faces.config.ConfigureListener

        </listener-class>

    </listener>

  

  <servlet>

    <servlet-name>Faces Servlet</servlet-name>

    <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>

    <load-on-startup>1</load-on-startup>

    <url-pattern>*.jsf</url-pattern>

  </servlet-mapping>

  <welcome-file-list>

    <welcome-file>index.jsp</welcome-file>

  </welcome-file-list>

</web-app>

类库：

服务器是tomcat6.0

工程结构：

test2.xhtml 页面代码

</html>

用IE访问页面总是弹出下载框：

高手指点一下，谢谢。 --------------------编程问答-------------------- 自己顶。。。 --------------------编程问答-------------------- 头怎么是<?xml version="1.0" encoding="UTF-8"?>？
删了试试 --------------------编程问答-------------------- 看不到IE弹出来的对话框，你发的图片没有显示！重新截一个出错信息
