Hi, I want know if it is possible with Hibernate to connect to several Databases hosted in different servers.
Thanks.

Yes

Not from the same session factory. You would need to use a seperate session factory for each underlying database.

Ok. But what is the configuration of the hibernate.properties file considering the two databases hosted in different servers?

If I understand your question correctly, you need two seperate Configurations. A Configuration is responsible for generating a SessionFactory. So basically you would just construct two different Configurations (each describing the connection characteristic and class mapped to each of the underlying databases) and then ask each to build a seperate SessionFactory.

You would need to explicitly specify the config file for at least one of these Configurations. Your best bet would be to use a common hibernate.properties for the common config attributes and then to have xml config files for each of the Configuration objects you need to construct.
