使用jbpm4.4，hibernate-3.6.8.jar，oracle驱动classes12.g10.jar

试过换hibernate低版本，试过换oracle驱动，但问题还在。

请问怎么解决？

我前几天也遇到这个问题，就是数据库表字段有lob类型的，就插不进去，报“[org.hibernate.util.JDBCExceptionReporter] 不允许的操作: streams type cannot be used in batching
”
后来是发现ORACLE驱动不是最新的（odjbc12的驱动），换成Oracle10.1.0版本同时发布的odjbc14.jar驱动就好了！
