struts2与spring集成遇到如下问题，已经调了很久，还是没有找出原因，希望各位大牛帮忙解惑，找出其中端倪！

导入的相关jar如下：

index.jsp如下：

<%
final String url = request.getContextPath() + "/index/index.action";
response.sendRedirect(response.encodeURL(url));
%>

目录结构如下：

myeclipse控制台出现的问题：

浏览器访问：http://localhost:8080/app出现错误如下：

还有一个奇怪的现象是：

如果我把

改为

index.jsp改为

<%
final String url = request.getContextPath() + "/index.action";
response.sendRedirect(response.encodeURL(url));
%>

浏览器再次访问：http://localhost:8080/app出现错误如下：

网上找了查看了很多，都说是把配置文件放到类路径下，尝试了也不行，而且我这样写应该也是可以的吧。

花了很长时间，真没辙，希望各位指点迷津，谢谢！
