我按照一个视频教程试着连接数据库（使用的是eclipse,驱动也都配好了）,我每一个步骤都是安装教程上面设的，但是最后我的一运行就是出现错误．
代码如下：
<%@ page language="java" contentType="text/html; charset=gbk"
pageEncoding="gbk"%>
<%@ page import="java.sql.*"%>
<%
Class.forName("com.mysql.jdbc.Driver");
String url = "jdbc:mysql://localhost/bbs?user=root&password=root";
Connection conn = DriverManager.getConnection(url);
%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gbk">
<title>Insert title here</title>
</head>
<body>
</body>
<%
conn.close();
%>
</html>
／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／／
下面的是运行的错误：
