Simple mapping issue for Hibernate newbie

[Tom Collins]

I have a one-to-many relationship (at least I think) between a product and production state table. A product can be in only one of the pre-defined states of production at a time (e.g. "in production", "inspection", etc.) The product table has a foreign key called production_state_id. Because the production state table only has a primary key and a description, it really doesn't merit an object in Java.

I currently have a product object which contains a string indicating its state of production. My question: how do I map this relationship? This is probably a ridiculously simple problem, but for all the reading up I've done, I can't find an answer for this situation. The following is my mapping file for the product (Note: I used product throughout the post as a generic term for the industry specific product "die" - i.e. tool & die).

<hibernate-mapping>
    <class name="hwdies.pojos.AbstractDie" table="DIES" discriminator-value="GENERIC_DIE">
        <id name="id" type="java.lang.Integer" column="die_id">
            <generator class="native"/>
        </id>
        <discriminator column="die_type" type="string"/>
        <property name="batchNum" column="batch_num" type="java.lang.String"/>
        <property name="versionNum" column="version_num" type="int"/>
        <property name="internalFileNum" column="internal_file_num" type="java.lang.String"/>
        <property name="scheduledDate" column="scheduled_date" type="java.sql.Date"/>
        <property name="inspectDate" column="inspect_date" type="java.sql.Date"/>
        <property name="approvalDeterminedDate" column="status_determined_date" type="java.sql.Date"/>
        <property name="disposalDate" column="disposal_date" type="java.sql.Date"/>
        <property name="comments" column="comments" type="java.lang.String"/>
        
        <!-- productionState is a string object member, prod_state_id is a foreign key integer to prod_state table
        <many-to-one name="productionState" column="prod_state_id"/>
        -->
        
        <subclass name="hwdies.pojos.SinglePartDie" discriminator-value="SINGLE_PART_DIE">
            <many-to-one name="part" column="part_id" class="hwdies.pojos.Part"/>
        </subclass>
        
        <subclass name="hwdies.pojos.MultiPartDie" discriminator-value="MULTI_PART_DIE">
            <set name="parts" table="DIE_PART">
                <key column="die_id"/>
                <many-to-many column="part_id" class="hwdies.pojos.Part"/>
            </set>
        </subclass>
    </class>
</hibernate-mapping>
