Hibernate操作Oracle报错 java.sql.SQLException: 不支持的特性

今天测试hibernate的主键生成策略的时候，出现以下错误信息：（hibernate是3.4.0版本，数据库是oracle9i）

错误描述：

 在网上google下，说是驱动包的问题，按照解决方法，把原来oracle自带的ojdbc14.jar换成了网上提供下载的ojdbc14.jar，问题得到解决，【在网上提供下载ojdbc14.jar中的 META-INF中的MANIFEST.MF 中看到，Implementation-Time:    Sat Feb  2 11:40:29 2008，而原来oracle自带的ojdbc14.jar中的 META-INF中的MANIFEST.MF 中看到，Implementation-Time: "Thu Apr 25 23:14:02 2002"】，先提供该ojdbc14.jar的下载，^_^
