请教，JDBC与SQL Sever 连接出错

我装的sql sever2000,系统为W2K，用的是sever 2005 for JDBC驱动，运行程序为下面的代码，
import java.sql.*;
        public class testjdbc{
            public static void main(String[] args){
                try{                   
 //load the Driver                    
  Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");               
   String url="jdbc:microsoft:sqlserver://222.27.110.17:1433;DatabaseName=mydb";      
      String user = "administrator";
        String password = "woaiwojia";
        //connecte to the server 
        Connection conn = DriverManager.getConnection(url,user,password);    
       // Connection conn = DriverManager.getConnection(url,user，password);
        //send the SQL command    
         
Statement stmt = conn.createStatement();   
          String sql = "SELECT * FROM Student";   
           ResultSet rs = stmt.executeQuery(sql);
                    //output the result         
            System.out.println("=====SELECT * FROM Student=====");               
            System.out.println("Sno\t\tSname");         
           while(rs.next())    
             System.out.println(rs.getString("Sno")+ "\t\t" +rs.getString("Sname"));
                    //close the connecte      
              conn.close();           
     }
       catch(SQLException e){   
                 System.out.println("SQL State :" +e.getSQLState());       
        System.out.println("SQL Error Code :" +e.getErrorCode());               
         }
      catch(Exception e){      
              e.printStackTrace();        
        }         
   }       
 }
