jsp中如何连接sql server express 2005
Class.forName( "com.microsoft.jdbc.sqlserver.SQLServerDriver ").newInstance();
String   url= "jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=testdb ";
  String   user= "sa ";
  String   password= "123456 ";
  Connection   conn=DriverManager.getConnection(url,user,password);
上面是以前连接sql   2000的代码，怎么修改后可以连到sql   server   express   2005啊？
驱动程序要不要改？
