Ok, after a good read on [1] and [2], I could understand that what I
want to do [3], right now, is not implemented in cayenne. Cayenne
only supply table-per-class-hierarchy feature.
Is that right?

Horizontal inheritance is also implemented now (3.0M6). However, you should
watch the jira task [4] to see when vertical inheritance is being worked on. In
the short term, you may be able to implement what you need using the other two
ways to model inheritance; for the most part, your Java code will not change
when you change your database implementation of how the inheritance is
represented.
