一个简单的文件：request.jsp
帮忙看一下
<%@ page import="java.sql.*" contentType="text/html;charset=GB2312" %>
<html>
<body>
<%
request.setCharacterEncoding("GB2312");
String name = request.getParameter("name");
Byte[] b = name.getBytes("");
String s = new String ( b ) ;
name=s;
%>
<%= name %>
</body>
</html>
运行后有错误：
org.apache.jasper.JasperException: Unable to compile class for JSP

谢过，刚刚被人点拨，大小写问题
Byte[] b = name.getBytes();里面的Byte->byte;呵，谢谢你！
