为什么这样发布到服务器在网页打开报错
<%@ page language="java" import="java.util.*,java.io.*" contentType="text/html; charset=utf-8"%>
<%
response.setCharacterEncoding("text/html;charset=utf-8");
out.println("<h1>response内置对象</h1>");
out.println("<hr>");
PrintWriter pw=response.getWriter();
pw.println("大家好,我时PW的对象PW");
%>
