Inheritance depth?

Say I have a class hierarchy such that Foo is primary superclass, having two subclasses Bar and Baz, and subclass Bar has two further subclasses of its own, Qux and Qax.

Can I reflect this in a Hibernate XML mapping file using the table-per-hierarchy? Can a subclass contain further subclasses? The examples I've seen all stop with a single layer of inheritance.

From Persistence with Hibernate:

Quote:

The <subclass> element can in turn contain other nested <subclass> elements, until the whole hierarchy is mapped to the table.

So that answers that.

Hi,

we have nested <subclass> but we don't have option to specify discriminator column in the subclass to further subclass it.

can some one please tell me how to implement multilevel inheritance by using nested <subclass>.

Thanks in advance.
