public class BuildingHibernate implements Building {
...
protected OwnerImpl owner;
}

public class OwnerImpl extends PeopleImpl
implements Owner
{

public OwnerImpl()
{
}

}

public class PeopleImpl
implements People
{


public PeopleImpl()
{
}

protected String name;
protected String lastname;
}


How should I map component superclass fields?
