配置的hibernate版本是hibernate-release-4.2.4.Final.原本buildSessionFactory()方法被废弃后用新方法依然无法通过…报错如下

菜鸟求解答,看的是韩顺平2011的hibernate视频,视频中用的版本是3,jar包有很多不一样的,就把目前4里有的jar包全都引入项目~~不知做法是否正确,顺便问一下hibernate普遍用的版本是多少~谢谢各位大神~~答案正确绝对按时结贴~ |

 50分 |
目测Oracle的数据库jar包没有加进去
|
 |
64位机器引入了ojdbc6.jar依然报错,请问一下org.h2.driver是什么包??还是我用的hibernate的版本不对的原因? |
50分 |
srb.applySettings(configuration.getProperties()).buildServiceRegistry();
|
|
谢谢两位,已经解决啦~纯散分给二位~ |
|
多谢楼主了
|

楼主，我也遇到了类似的问题，你是怎么解决的啊？
