[HIBERNATE醒目]请问如何解决commit failed的错误?

[tommyhero]

我是用ejb+struts+dao的，可以查出结果来，但是会出现下面的commit failed的错误，请问大家为什么？是与事务有关系吗？
=================================================

, cemployee0_.EMP_SEX as EMP_SEX, cemployee0_.DEPT_ID as DEPT_ID, cemployee0_.HE

这里不好解决这种问题。你应该去找专家。搜索以前的帖子吧，现在有点深度的问题，这里都难以解决，失望。

终于解决了！把ejb的事务管理改成“bean”就行了，太不可思议了，不但解决了我另外一个帖子中的问题，连这个问题都不再出现了。
官方文档里并没有说ejb用什么方式管理吧？我个人觉得大概的原因也许是容器管理不允许在业务中出现管理事务的代码，因为hibernate里内建了管理事务的代码，所以容器管理不行而bean管理可以。请高手指教
