Question

我在ejb应用程序中使用hibernate（4.2.7）持久保存实体时遇到问题，并且真的需要一些建议。以下是我的hibernate配置文件中事务工厂和事务管理器的配置。

    <property name="hibernate.transaction.factory_class">
        org.hibernate.transaction.CMTTransactionFactory
    </property>
  <property name="hibernate.transaction.manager_lookup_class">
    org.hibernate.transaction.WebSphereExtendedJTATransactionLookup
    </property>

当有数据库异常时，例如，将空值传递给非空列，约束问题等，我们得到以下异常

[5/22/16 15:15:21:481 MYT] 000000b7 RegisteredSyn E   WTRN0074E: Exception caught from before_completion synchronization operation: java.lang.UnsupportedOperationException

由于我们无法确定实际问题，我们的数据库是Oracle。有什么办法可以让我们得到确切的数据库异常？

任何线索都会非常有帮助。谢谢

带有hibernate的WebSphere 8.5：UnsupportedOperation异常
