----------------解决方案--------------------------------------------------------
你用的是jdbc-odbc桥连接吧，在操作系统中设置的数据源是不是有问题？
----------------解决方案--------------------------------------------------------
你要使用的jdbc驱动 把那3个炸包考到 jre\lib\ect我记得是这个目录下面
要是jdbc-odbc桥的话不会出这个问题 应该是别的异常

都不说具体点............................
