I'm using
Hibernate 2.1.2
Spring 1.0.1
OsCache 2.0.2

In my use case I'm using both JDBC and Hibernate to update data.
I'm using the second-level cache to cache the data. And when I update
the data I also want the second-level cache to be updated.

The problem is that when I use JDBC to update the data the second-level cache is of course not updated.

How can I avoid this?

I understand that I can use SessionFactory.evict but is there something better. For example can I tell Hibernate to execute the update query. And will the second-level cache be updated in that case?

when an object is updated even in hibernate, most of the time it is evicted from the second level cache (not updated).

Ok. I will just have to evict the objects after running the SQL update with JDBC.
