Hello,

I want to implement a qualified M:N mapping.
As explained in tutorial 3, I have created an association class.

My problem is how to retrieve (or store) info with this association class between the 
two classes?
Is it possible to have a "packages" attribute in the Workstation class and simply call 
the method "getPackages" to retrieve all the packages in a workstation?
How can I do that?

Here is the class-diagram:

class Package
-------------
int packageID; (PK)
Sring packageName;
String packageType;
Collection packageWorkstations


classs Workstation
------------------
int workstationID; (PK)
String workstationName;
String workstationType;
Collection packageWorkstations;


class Package_Workstation
-------------------------
int packageID; (PK)
int workstationID; (PK)
int rule_order;
Package package;
Workstation workstation;

There is a M:N relationship between Package and Workstation. The Package_Workstation 
class is the association class. The relationship is qualified with the field 
"rule_order".


Thanks for your help
Sylvain
