Hello guys
i understand and i did without problem a relation many-to-many between 2 classes but when each has one varibale how pk/id
like
http://www.hibernate.org/hib_docs/v3...ional-join-m2m
Code:
<class name="Person">
    <id name="id" column="personId"> 
        <generator class="native"/>
    </id>
    <set name="addresses" table="PersonAddress">
        <key column="personId"/>
        <many-to-many column="addressId"
            class="Address"/>
    </set>
</class>
<class name="Address">
    <id name="id" column="addressId">
        <generator class="native"/>
    </id>
    <set name="people" inverse="true" table="PersonAddress">
        <key column="addressId"/>
        <many-to-many column="personId"
            class="Person"/>
    </set>
</class>
my problem is when one class has its pk like composite key and the other no
i saw this link
http://www.hibernate.org/hib_docs/v3...key-manytomanybut it a little confuse for me
this is my hbm.xml pk declarations
Code:
<hibernate-mapping
>
    <class
        name="com.modelo.entidades.CabeceraAlmacen"
        table="CabeceraAlmacen"
        discriminator-value="CABALM"
    >
        <composite-id
            name="almacenPK"
[b]            class="com.modelo.entidades.AlmacenPK"[/b]
        >
                     <key-property
                        name="idnumero"
                        type="java.lang.String"
                        column="idnumero"
                        length="6"
                />
                     <key-property
                        name="serie"
                        type="java.lang.String"
                        column="serie"
                        length="3"
                />
        </composite-id>
and the other class
Code:
<hibernate-mapping
>
    <class
        name="com.modelo.entidades.ArticuloNoAuto"
        table="ArticuloNoAuto"
    >
        <id
            name="idArticuloNoAuto"
            column="idArticuloNoAuto"
            type="java.lang.String"
            length="20"
        >
            <generator class="assigned">
             </generator>
        </id>
maybe some friendly member can share some code or show me how
resolve this situation
many-to-many with composite key attribute
