Hi,
Struggling with a problem the hole day and wonder if anyone may have an easy solution..

I have a Customer and Car class with a many-to-many relationship.

pubilc class Customer {
@id
private id;

@ManyToMany
@IndexColumn(name="idx")
private List<Car> cars = new ArrayList<Car>();

@Column
private float discount;
-- getters/setters --
}

pubilc class Car {
@id
-- other variables + getters/setters.
}

This generates a relationtable customer_car with customer, car and idx as variables.
However I would like to have the 'discount' variable from the Customer class to appear in the relation table customer_car as well so I have customer, car, idx and discount in the realation table.

/M

Read this: http://hibernate.org/42.html

you need to map the association table as an explicit entity and put your property in it.
The many to many will then become a one to many // many to one
