来源：百度文库 编辑：偶看新闻 时间：2024/05/02 15:05:56
web.xml
404 /building.jsp
500 /error.jsp
JSP页面的关键在于
1 isErrorPage="true"
2 response.setStatus(HttpServletResponse.SC_OK);
building.jsp
<%@ page language="java" contentType="text/html; charset=GBK" isErrorPage="true" pageEncoding="GBK"%>
<%response.setStatus(HttpServletResponse.SC_OK);%>
<%
/**
* 本页面是在客户查找的页面无法找到的情况下调用的
*/
response.setStatus(HttpServletResponse.SC_OK);
%>

error.jsp
<%@ page language="java" contentType="text/html; charset=GBK" isErrorPage="true" pageEncoding="GBK"%>
<%@ page import="java.io.*,java.util.*"%>
<%response.setStatus(HttpServletResponse.SC_OK);%>
程序发生了错误，有可能该页面正在调试或者是设计上的缺陷.
你可以选择
