Hibernate version:2

I have a very small question:
Is it possible to make a relation (eg. many-to-many) with a propery?

Something like:


???

Let's start by setting up relationships between classes such as User, Roles


Class User contains
email:String
password:String

Class Role contians
name:String
descripition:String


Both the classes USER associated with Roles. A many-to-many relationship exists between Users and Roles (that is, association with independent lifecycles).

User associated with roles Many-to-many Association Unidirectional (Users-->Roles)

[User.java]
/**
* @return
* @hibernate.bag
* table="TBL_JOIN_USER_ROLE"
* cascade="all"
* inverse="true"
*
* @hibernate.collection-key
* column="FK_USER_ID"
*
* @hibernate.collection-many-to-many
* class="net.sf.hibernateExamples.Role"
* column="FK_ROLE_ID"
*
*/
public List getRoles() {
return roles;
}



create table TBL_ROLE (
PK_ROLE_ID BIGINT NOT NULL AUTO_INCREMENT,
VC_DESCRIPTION VARCHAR(200),
VC_NAME VARCHAR(20),
primary key (PK_ROLE_ID)
)

create table TBL_USER (
PK_USER_ID BIGINT NOT NULL AUTO_INCREMENT,
USER_TYPE VARCHAR(255) not null,
FK_GROUP_ID BIGINT,
VC_EMAIL VARCHAR(82) not null unique,
primary key (PK_USER_ID)
)

create table TBL_JOIN_USER_ROLE (
FK_USER_ID BIGINT not null,
FK_ROLE_ID BIGINT not null
)

Yes i know that. That wasn't the question.

Is it possible to give the relation between 2 object an extra propery.
no the objects but the relation.

So the relationschip between user & role gets a relation for example Date (just an example).

Is _that_ possible?

composite element?
or maybe ternary association if you want an entity instead of a 'Date'.
Check the reference guide.
