这是页面代码:
<%@ page language="java" contentType="text/html; charset=gb2312"%>
<%@ page import="Message.*" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>Insert title here</title>
</head>
<body>
<JSP:useBean id="MsgJudge" class="Message.MessageLoad1Judge" scope="page"/>
<%
int i=0;
String Message=request.getParameter("Message");
if(Message==null){
response.sendRedirect("WarmingNiMing.jsp");
i++;
}
byte b[]=Message.getBytes("ISO-8859-1");
<%@ page language="java" contentType="text/html; charset=gb2312"%>
<%@ page import="Message.*" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>Insert title here</title>
</head>
<body>
<JSP:useBean id="MsgJudge" class="Message.MessageLoad1Judge" scope="page"/>
<%
int i=0;
String Message=request.getParameter("Message");
if(Message==null){
response.sendRedirect("WarmingNiMing.jsp");
i++;
}
byte b[]=Message.getBytes("ISO-8859-1");
...
<JSP:useBean id="MsgJudge" class="Message.MessageLoad1Judge" scope="page"/>
不懂啊...
为什么不直接new 呢
你说的创建对象是这个吧?
<JSP:useBean id="MsgJudge" class="Message.MessageLoad1Judge" scope="page"/>
我也就是不会用这个.
叫我做就是,去掉这句话,然后
<%
MessageLoad1Judge MsgJudge = new MessageLoad1Judge();
%>
