Hi everybody,
in my project I've to connect 4 databases, each one using a different instance of Informix.

It is possible to do this with Hibernate?
What do I do to have the connection?
In that way I've to change hibernate.cfg.xml ?

Excuse me for my poor english anh Thanks for the help !!!

You need to create a SessionFactory for each database.

HibernateUtil can be refactored reasonably easily to support multiple session factories. Just use a flag passed to getSession() to indicate which database you want to work with.
