数据库连接问题

这代码到我的机子上就怎么运行不了啊
我是新手望知道的指点下,sqlserver应该没有问题我用asp可以连接成功
<%@ page contentType="text/html;charset=gb2312"%>
<%@ page import="java.sql.*"%>
<html>
<body>
<%Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver").newInstance();
String url="jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=shop";

String user="sa";
String password="";
Connection conn= DriverManager.getConnection(url,user,password);
Statement stmt=conn.createStatement

(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);
String sql="select * from userinfo";
ResultSet rs=stmt.executeQuery(sql);
while(rs.next()) {%>
您的第一个字段内容为:<%=rs.getString(1)%>
您的第二个字段内容为:<%=rs.getString(2)%>
<%}%>
<%out.print("数据库操作成功,恭喜你");%>
<%rs.close();
stmt.close();
conn.close();
%>
</body>
