Hibernate version:
Hibernate 3-alpha

"Directory" is-a "File" and a "Directory" can contain one or more "Files" and/or one or more "Directories".

I'm trying to map the above relationship, but wasn't able to do much. I could try to have a table-per-class mapping, but would that allow the containment relation with the parent?
