Insert not being reflected in later Select - sql

Question

I’m developing a web app with JSF and Hibernate, and I’m facing a problem with Hibernate. At some point, I want to INSERT a row in a table. Just after that, I want to retrieve the 3 last inserted elements of the same table. The problem is that the INSERT is being made correctly (I checked that with a DB Client), but when I try to retrieve those 3 elements, the one I have just inserted is not returned by the SELECT statement. It seems like a kind of hibernate session problem, not reflecting the change when I make the SELECT. I attach the relevant part of the code:
hibernate.cfg.xml:
