Cannot create JDBC driver of class '' for connect URL 'null'

 <Resource name="jdbc/mldn" type="javax.sql.DataSource" username="root" password="mysqladmin" driverClassName="org.gjt.mm.mysql.Driver" maxIdle="30" maxWait="5000" url="jdbc:mysql://localhost:3306/mldn" maxActive="100"/>

  <resource-ref>
      <res-ref-name>jdbc/mldn </res-ref-name>
      <res-type>javax.sql.DataSource </res-type>
      <res-auth>Container </res-auth>
    </resource-ref>

我的解決辦法：

我之前用的驅動包是mysql-connatot-5.0.8,試了很久都不行，最後是把我的這個5.0.8的驅動替換爲老師的驅動mysql-conator-5.0.4，並且重新創建一個數據庫連接（DB Driver），然後http://hi.csdn.net/link.php?url=http://blog.csdn.net%2Fleidengyan說的方法修改，結果運行通了

注意創建hibernate鏈接數據庫時，要將vo下的user.hbm.xml文件內的catlog='mldn'刪除掉（視頻中有提到）
