Hi, I have a structure similar to this this:
class Zoo { Animal animal; } class Zebra implements Animal { } class Donkey implements Animal { } All classes are annotated as PersistenceCapable etc and enhanced. I get this error: javax.jdo.JDOUserException: Field "animal" is declared as a reference type (interface/Object) but no implementation classes of "Animal" have been found! Any suggestions? BTW, the cos are very sparse when it comes to persisting class hierarchies.
