what do you think of
http://joafip.sourceforge.net/database/dbvsjoafip.html
I created joafip to manage more objects than memory can contains.
I can also be use to persist data model.

I use an hibernate ejb3 dao to insert values in a mysql database, the code
runs without exceptions but my table is empty, the autocommit is true and
i don't undestand why...
Is there other type of commit in the hibernate ejb3 dao?
