jsp

在jsp中出现中文乱码怎么解决？
我的代码是
<%@ page contentType="text/html; charset=gb2312" language="java" %> <% request.setCharacterEncoding("GB2312");%><HTML>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">; <title>jsp教程</title>
<link rel="stylesheet" type="text/css" href="styles.css" />
<style type="text/css">　　
h1{ text-decoration: none; white-space: nowrap; padding-bottom: 10px; color:#66FF66; }
h1:hover { background: url('http://blog.sina.com.cn/pic/4723cdbf020002nm') repeat-x 100% 100%; }
h5{ text-decoration: NONE; color: #6633FF;}
h5:hover {font-weight: bold;color: #CC00FF;}　　
</style>
<script language="javascript">
<!--
    function handle(){
var mousex;
var mousey;
mousex=window.event.x;
mousey=window.event.y;
keycon.style.left=mousex;
keycon.style.top=mousex;
}
document.onclick=handle;
-->
</script>
</head>
