The problem is when i have repeated columns, so that i have to put insert="false" and update="false" in the many-to-one association.
When i save an object , the associated many-to-one object is not saved. At least i don't find it on the database.

For example:

Code:
       <composite-id>
                     <key-property
                        name="assetCode"
                        type="java.lang.String"
                        column="cod_valor"
                />

                     <key-property
                        name="company"
                        type="java.lang.String"
                        column="cod_empresa"
                />

        </composite-id>

         <many-to-one
            name="assetDesc"
            class="classxxxx"
            cascade="all"
            outer-join="auto"
            update="false"
            insert="false"
            access="property"
        >
            <column
                name="cod_valor"
            />
            <column
                name="cod_empresa"
            />
        </many-to-one>


Well . hope some solution exists. Thanks.

Yeah, i tried that. And works fine.

Now, the problem remains when multiple many-to-one relationships share columns. In this case key-many-to-one doesn't allow to share columns and it doesn't have the attributes update and insert to set the "false".

NOTE: the database schema can't be changed

Example:

Code:
<composite-id
            name="pkReal"
            class="net.technisys.bancoval.credival.domain.service.portfolio.guarantee.asset.AssetGuaranteePrimaryKey"
        >
                     <key-property
                        name="assetCode"
                        type="java.lang.String"
                        column="cod_valor"
                />

                     <key-property
                        name="company"
                        type="java.lang.String"
                        column="cod_empresa"
                />

                     <key-property
                        name="personIntCode"
                        type="java.lang.String"
                        column="cod_int_persona"
                />

                     <key-property
                        name="portfolioCode"
                        type="java.lang.String"
                        column="cod_cartera"
                />

        </composite-id>

<many-to-one
            name="portfolioGuarantee"
            class="net.technisys.bancoval.credival.domain.service.portfolio.guarantee.PortfolioGuaranteeBusiness"
            cascade="none"
            outer-join="auto"
            update="false"
            insert="false"
            access="property"
        >
            <column
                name="cod_empresa"
            />
            <column
                name="cod_cartera"
            />
        </many-to-one>
       
        <many-to-one
            name="personGuarantee"
            class="net.technisys.bancoval.credival.domain.service.portfolio.guarantee.asset.person.PersonGuaranteeBusiness"
            cascade="none"
            outer-join="auto"
            update="false"
            insert="false"
            access="property"
        >
            <column
                name="cod_empresa"
            />
            <column
                name="cod_int_persona"
            />
            <column
                name="cod_cartera"
            />
        </many-to-one>

In the example above cascade is set to "none", but i also tried "all" and didn't work.

It is quite resonable to enable cascade on a many-to-one with insert="false" update="false".

Yes, i suposse.

But i don't know if the problem i have is clear.

I want to have multiple many-to-one that share columns. Also i want those columns to be part of the primary key.

I haven't found how to tell hibernate to insert data in the tables associated by the many-to-one relationships. (Because i'm forced to use update="false" insert="false" and i cant use key-many-to-one).
