我创建了一个新的 IceFace 项目并尝试在本地主机上运行它，但是收到以下错误消息：

我的 WebContext 下的两个文件是 index.jsp，它重定向到 index.jsf，另一个文件是 index.xhtml，其中包含以下内容：

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

     </h:panelGrid>
    </ace:panel>
       </h:form>
    </h:body>
</html>

我尝试将欢迎文件列表切换为

  <welcome-file-list>
    <welcome-file>index.xhtml</welcome-file> <!--switched extension from html to xhtml -->
  <welcome-file-list>

有了这个更改，我的 localhost 不会崩溃，但是我得到一个空白页面（我的 JSF 元素都没有出现）我有一种感觉，因为我的 JSf 标签都没有被解析，但是我真的不知道在哪里问题是，谁能帮帮我？

其他信息：我使用 Eclipse Java EE IDE for Web Developers ICEFACES 3.3.0 Tomcat 3.0

谢谢。

更新：

将我的 web.xml 欢迎文件列表更改为

  <welcome-file-list>
    <welcome-file>index.xhtml</welcome-file>
  </welcome-file-list>

并将我的 servlet 映射更改为

  <servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.xhtml</url-pattern>
  </servlet-mapping>

现在没有崩溃，但是我的 JSF 元素没有出现，我只得到一个空白页。

更新：

Web.xml

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

  <servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.xhtml</url-pattern>
  </servlet-mapping>

我在url-pattern标签内尝试过 .jsf 和 .xhtml 都没有运气

索引.jsp

<html>
<head>
</head>
<body>
      <%
        //response.sendRedirect("./index.jsf");
    %> 

    <jsp:forward page="main.jsf"/>

</body>
</html>

在让我的页面加载后，它变成空白，所以我右键单击我的页面并查看源代码，这就是我发现的......

     </h:panelGrid>
    </ace:panel>
       </h:form>
    </h:body>
</html>

任何想法为什么会发生这种情况？
