我在My SQL 中建了一个学生信息表。
写了一个查询JSP 页面：
<%@ page language="java" import="java.util.*" pageEncoding="gb2312"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">
<title>信息查询</title>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">
<!--
<link rel="stylesheet" type="text/css" href="styles.css">
-->
</head>
<body>
<h2 align="center">客户信息查询</h2>
<form action="ch13/customerByName.jsp">
<center>
<p>请输入客户姓名：<input type="text" name="customerName">
<input type="submit" value="提交">
<input type="reset" value="重置">
</center>
</form>
</body>
</html>
例外写了一个接收的页面 ：
<%@ page language="java" import="java.sql.*,java.util.*" pageEncoding="gb2312"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<base href="<%=basePath%>">

但是老是提示客户端错误： 显示不出结果。。请各位大侠帮小女子看看！！！谢谢！！！
