persistence.xml for development and another for production?

I have my persistence.xml set to a local database.

<property name="hibernate.connection.url" value="jdbc:mysql://localhost:3306/meubanco"/>
<property name="hibernate.connection.username" value="usuario"/>
<property name="hibernate.connection.password" value="senha"/>

It turns out that the development and production environments should have different configurations, because in production the DB may be located on another server and have different user and password.

How do I do this automatically?
