Hibernate multiple databases

Hi,

For our current project we have the need to be able to connect to
multiple databases using Hibernate.
I have seen the blog post of Taha
(http://tawus.wordpress.com/2012/03/03/tapestry-hibernate-multiple-databases/)
and was wondering if there exists a library based on this or similar
that I can use as is? Else I will have to investigate in creating one
myself.

Greetings Nathan
