jsp连接sqlserver出现问题

[ember_zhou]

Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");//加载驱动程序
Connection con=DriverManager.getConnection("jdbc:odbc//212.70.151.121:dbname","user","pwd");//取得数据源并进行连接

提示错误是：
java.sql.SQLException: No suitable driver
at java.sql.DriverManager.getConnection(DriverManager.java:532)
at java.sql.DriverManager.getConnection(DriverManager.java:171)
at DBconnTest.main(DBconnTest.java:14)

请问是什么问题啊？

[Hellohuan]

Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection con=DriverManager.getConnection("jdbc:odbc:books","sa","") ;
Statement stmt=con.createStatement();
ResultSet rst=stmt.executeQuery(SQL 语句);

要连接的不是本地数据库，而是别的主机上的数据库啊，怎么写？
