刚接触hibernate，这个问题纠结了一天了，网上各种方法都试过了，依旧提示
No suitable driver found for jdbc:mysql://localhost:3306/test
用的是hibernate4，以下几个应该注意的地方都检查过了，没有问题：
1、jdbc-connector的jar包添加到WEB-INF/lib下；
2、url格式正确；
3、jdbc-connector的jar包添加到javahome/jre/lib/ext下。
以前用hibernate3访问数据库的时候没有出这问题啊。求解答；以下是console输出：

以下是hibernate.cfg.xml内容：
