Is there any way to peek into a Secondary level cache to see its contents. In addition, can we manipulate the data in the cache ( delete selected data/objects since we no longer will be using it, refresh some stale data if the user already knows that the data was externally modified in the database). Are there any external tools that ...

6. Can I determine if something is in the cache? forum.hibernate.org
Well, that didn't seem to work. I guess the idea is that the Session knows that 2 instances of YourEntity that have the same id property ought to be equivalent? That makes sense but it doesn't seem to work for me. (when I try session.getIdentifier(anEntity) I *do* get a string that I recognize as being the ID for that entity) It's ...

I'm using EHCache with Hibernate. The caching works, but entities are cached in wrong regions.

But if I use EHCache's statistics to look at the cache I see many the elements cached in a region named "ticketing-ear_ear,ticketing-ejb_jar,ticketing.tickets" which uses the default region's settings. The region "tickets" also exists, but it stays ...
