Hi,

Does anyone know how to associate, in Hibernate, to two classes via a map of sets:

SortedMap<key,SortedSet>

I have serached the forums and read all the Hibernate doco, but could not find such a thing explained.

To give some context:

+----------+ has +------+ departs from +---------+
|DealBundle|----------------| Deal |------------------| Airport |
+----------+ 1 0..* +------+ 1 1 +---------+
 |1 | 1
 | arrives at |
 +--------------------------+

I have an object, call it a DealBundle, which has a whole lot of Deal objects. The Deal objects are kept in multiple SortedSets which in turn are in a Map keyed by the departure Airport object.

public class DealBundle {

 public long id;

 public SortedMap<Airport,SortedSet<Deal>>
 dealsByDepartureAirport;
}

public class Deal {

 public long id;
 public Airport departureAirport;
 public Airport arrivalAirport;
 public float totalPrice;
}

public class Airport {

 public long id;
 public long IATACode;
 public long name;
}

I will appreciate any and every bit advice here because I am at a loss.

Cheers,
Evan
