Ternary association logic problem

Hello,

I have this relation that gives me headaches, I don't know how to map it to hibernate.
I have three first-rank classes; User, Element and Parameter.
An user has multiple elements and the user has multiple parameters per element.
The relation looks like this: UserPerElementPerParameter(userid,elementid,parameterid).
I tried a composite-element with an Element instance and one Parameter instance but then I get one compostie instance per element-parameter entry. What I want is a composite-element with an Element instance and a List of parameter instances.
Thanks in advance.

This is not a solution to my problem. I think I didn't describe it correctly.
This is what I want:

Code:

A - AB - B
        \ - AB(PK) C  -  C

So, A has a set/list of a composite entity which contains B and a Set/List of C. <composite-element> can's contain a <set> / <list> declaration so I wonder how I should do this.

Thanks for helping.
