Mysql找不到驱动，网页无法运行，请大牛指教
网页中填写注册信息后，提交，myeclipse里报错如下：
No suitable driver found for jdbc:mysql://localhost/jokeHome?useUnicode=true&characterEncoding=utf-8&allowMultiQueries=true}
* executeQuery{SELECT `username` , `password` FROM `jokehome`.`users` WHERE `username` ='asdf' AND `password` ='asdf' ;}
请问如何解决啊

[解决办法]
楼主你有注册驱动吗？就是class.forName("com.mysql.jdbc.Driver");这句代码！
