I am trying to implement a Hibernate version of Spring Security's ACL domain model.
e.g. http://static.springsource.org/spring-security/site/docs/3.1.x/apidocs/org/springframework/security/acls/model/Acl.html
It's (quite rightly) built around interfaces which my entities will implement.
I usually use annotations to configure Hibernate, but I obviously can't annotate Spring Security's interfaces.
I wonder if I can map them in an XML mapping file?
Most of the interfaces don't provide an ID candidate, so will Hibernate even allow me to used them as 'super classes' to my implementation entities?
I'm using Spring Security 3.x and Hibernate 3.x
Can I mix the xml definition for the Spring interfaces with annotations on the implementing entity classes or does the whole class hierachy have to be implemented in XML/

I may be able to partially answer my questions about IDs. It does appear to be a problem.
I tried adding



to hbm.xml and got an exception caused by:

org.hibernate.PropertyNotFoundException: field [id] not found on org.springframework.security.acls.model.Acl

The DTD seems to require and id but I was wondering whether it's possible to allow the subclasses to provide it?

I'm wondering if I can not worry about mapping the interfaces and just use my implementation class entities with something like:



I will give it a try.
