Join table with extra value

[Christian Defoy]

Hello,

I have two objects, A and B, that are involved in a many to many
relationship.  That portion works ok if class A contains:

    @ManyToMany( fetch=FetchType.EAGER, cascade=CascadeType.ALL )
    @JoinTable( name="a_b", [EMAIL PROTECTED]( name="a_id",
referencedColumnName="a_id" ),
                [EMAIL PROTECTED]( name="b_id",
referencedColumnName="b_id" ))
    private Set<B> mappedBs;

My problem is that the relationship between A and B must contain an
additional value.  The join table between A and B looks like this:

create table A_B
(
    a_id  integer not null,
    b_id  integer not null,
    value integer
);

Should I define the mapping as A (OneToMany) A_B (ManyToOne) B and
create an object for A_B?  If so, how do I do that?

Thanks in advance!

Christian
