Onegaishimasu... Hayaku kudasai!!

Multiple config files, multiple session factories, etc.
Curtis ...

I should do that... but i have milions of tables....

Is a admsys for a leasing company.... I have so much tables and if i duplicate all configs.... is spend time until death!!!

dont have another way kudasai???

I assumed you wanted to make multiple entries for the same mapping -- in that case you need multiple session factories. You only need to duplicate the .cfg.xml file - one for each session factory. Then, you have to deal with building multiple session factories and retrieving sessions from the correct one, etc.

If you want to access multiple databases as if they were one db, I don't know how to handle that with Hibernate. You should probably be looking to solve the problem at the db level (aliases or other things to unify the databases).

Good luck,

The System solve the Session Factorys by himself... Is automatic in all terms... Cuz we need a pool conection and to much sessions in same time... I realy need a way to manipulate 2 Databases in same hibernate session... In the hibernte.cfg.xml, have i a way to duplicate the lines that call mysql and replace the names??? maybe calling another with another name and host?? can i do that???

no, but you can change your Hibernate configuration dynamically.
use setProperty to provide the connection.
Still you will need two SessionFactories
