No. You can delete the object with a primary key and insert a new created one.

No you can't using Hibernate. Read the section on object identity in the Hibernate in action book.

You need to be asking yourself why you want to update the primary key. Have you mapped the primary key to a key with business meaning that is mutable?

If you absolutely have to change the primary key use JDBC and make sure that you clear the cache if you have a session open.
