Hibernate version:
H3.1 EJB3 Jboss 4.01RC2

Just wanted to verify. Is it currently not possible (using annotations) to specify a ternary relationship using a Map and an association as an index? The reference documents hint that this may be possible as an EJB3 extension. I am sure I could do this using the mapping files but I would like to create everything using annotations as this is a much more elegant solution. My other options would be to turn the ternary into an assocation class with ManyToOne relationships or possibly some sort of composite relationship. Any suggestions or comments on the best strategy would be welcome.

Thanks
