How to alter entity ID?

Hibernate 3.0.2:

I want to change the ID of an entity that already been persisted, although my mapping file assigns a "native" ID generator to the Entity.

If I setId() and update(), Hibernate throws:

org.hibernate.HibernateException: identifier of an instance of com.be.desktopbeautifier.server.DefaultTheme altered from 15 to 2

What is the correct way of doing this?

you cannot alter and ID, you can copy the object into a new one and delete the old one.
