已经在控制面板中设置了SQL数据源了.为什么连接数据库时还有问题
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%@ page import="java.sql.*"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body >
<%
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver").newInstance();
String url="Jdbc:Odbc:practise";
String user="sa";
String pwd="123";
Connection conn=DriverManager.getConnection(url,user,pwd);
Statement stmt=conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);
String sql="select * from login ";
ResultSet rs=stmt.executeQuery(sql);
if(rs.next())
{
out.println("right,login");
}
else
{
out.println("fail,not login");
}
rs.close();
stmt.close();
conn.close();
%>

但却提示下面错误:
