Hi,

It is possible. The only thing you have to do is create to configure two sessions with two "hibernate.cfg.xml" files.

In each 'cfg.xml' you list the mapping files to consider and these files don't need to be the same. So, you can map the same classes with different schemas in one database or in different databases...

Bye,

Charles

You can however not maintain associations between objects in different databases, or query over two databases, etc.
