Initializing database

I'm mapping some classes with Hibernate and I'd like to delegate both data model creation and data initialization to Hibernate. Is it possible?

In other words, is is possible to populate the initial data of the database in the very beginning of hibernate bootup?

The database creation can be done with hbm2ddl.auto set to create or create-update

For data initialization, this is business work, just creating objects and saving them. You can use hibernate xml features to specify your data as xml file.

It's "bussiness layer business" :). You're so right I'm populating the database at the startup, saving constants with Spring.

So does that mean that if I setup my data as xml, it will get inserted into the appropriate tables when hibernate creates the tables on the first run?

Can you please point me to instructions or examples for doing that.
