I want to map interfaces in my domain model. I want to have the setter for the id private so cannot specify this in the interface.

Is this possible?

This must be a common problem, I'm trying having the methods you want public in one MyInterface, and the ones you want private in HibernateInterface extends MyInterface.
Then an implementor has to implement HibernateInterface, and a 'user' uses MyInterface.

When I want to extend MyInterface I have to do MyExtensionInterface extends MyInterface and HibernateExtensionInterface extends MyExtensionInterface implements HibernateInterface and add the required extra getters.

I'm hoping this is going to work.

Anyone have a better method?
