Re: [Hibernate] Subclassing And "net.sf.hibernate.MappingException: No persister for" Exception

[Gavin King]

Not true, you can map interfaces as a superclass. But in this case 
Matthew is anyway using any <any> association by the looks of it, so he 
doesn't need to. Can't see the problem though.

I'm not 100% certain of this answer, but I believe the problem is that 
PaymentType is an interface instead of a class.  Hibernate can only 
persist a class.  (Even if it's an abstract class?)

I'm not sure why you didn't have problems persisting PaymentType directly.
