求解下面问题
我在eclipse中代码是：
<%@ page language="java" import="java.util.*,java.io.*" contentType="text/html; charset=utf-8"
pageEncoding="utf-8" %>
<%
response.setContentType("text/html;charset=utf-8"); //设置响应的MIMI类型
out.println("<h1>response内置对象</h1>");
out.println("<hr>");
// out.flush();
PrintWriter outer= response.getWriter(); //获得输出流对象
outer.println("大家好，我是response对象生成的输出流outer对象");
response.sendRedirect("Reg.jsp");//请求重定向会跳转到指定的jsp页面中
%>
运行后，总是出现下述界面
HTTP Status 404 – Not Found
Type Status Report
Message /JspInnerObjectDemo/response.jsp
Description The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.
