No suitable driver

我集成了ssh后，做了一个小测试，就是建了2个实体类，person.java     oranization.java    用ant xdoclet 生成表。
可是，后台报以下错误：首先声明的是，我已经引入了数据库的驱动程序，我用的是oracle  class12.jar   请问这是 哪里的问题啊。

解决方案 »

  1.   

    Could not obtain connection metadata
    java.sql.SQLException: No suitable driver 
    无法获得连接元
    没有合适的驱动。是不是驱动加错了，换个驱动试试。
      

  2.   

    No suitable driver 
    驱动有问题啊~~~
      

  3.   

    我用的是oracle数据库，加的驱动是class12.jar   我刚才又重新加了一遍，把原来的替换掉，可是还是不行那，同样的错误提示。
      

  4.   

    No suitable driver  驱动问题
