Debug level Hibernate log excerpt:


I am trying to create polymorphic associations to a table-per-class-hierarchy
in which one class multiply inherits from two other classes in the hierarchy.

For example:

DuckImpl implements Duck
BeaverImpl implements Beaver
Platypus implements Duck, Beaver


Ducks, Beavers, and Platypi are all stored in table ANIMAL
with descriminators
DUCK
BEAVER
DUCK,BEAVER

I need to be able to map these classes such that another class mapping
can associate to Duck and hibernate will load a DuckImpl or Platypus
as appropriate

How would I do this?
