Hibernate version: 3.1

Mapping documents:

Code:

    <class name="it.inform.w3.bean.ItemTypeProcessoConfigurazioneProprieta" table="W3T_PROPRIETA_CONFIGURAZIONI" select-before-update="true">
        <meta attribute="class-description">Proprieta configurazioni</meta>

         <composite-id name="id" class="it.inform.w3.bean.ItemTypeProcessoConfigurazioneProprietaPk">
               [b]<key-property    name="codentitt"  column="codentitt" type="long"/>[/b]            <key-property    name="codentpss"  column="codentpss" type="long"/>
            <key-property    name="codentcnf"  column="codentcnf" type="long"/>            
            <key-property    name="cafprp"      column="cafprp"      type="string" length="20"/>            
         </composite-id>
         
       <many-to-one class="it.inform.w3.bean.ItemTypeAttributo"  name="codentatt"  not-null="true" fetch="join" insert="false" update="false">
         [b]<column name="codentitt"/>[/b]
            <column name="codentatt"/>
       </many-to-one>
         
    </class>

Code:

    <class name="it.inform.w3.bean.ItemTypeAttributo" table="W3T_ATTRIBUTI" select-before-update="true">
        <meta attribute="class-description">Attributi</meta>

         <composite-id name="id" class="it.inform.w3.bean.ItemTypeAttributoPk">
               <key-property    name="codentitt"  column="codentitt" type="long"/>
            <key-property    name="codentatt"  column="codentatt" type="long"/>
         </composite-id>

        <property name="cafatt" type="string">
            <column name="cafatt" length="50" sql-type="string" not-null="true"/>
        </property>
        
        <property name="dscatt" type="string">
            <column name="dscatt" length="500" sql-type="string" not-null="true"/>
        </property>

        <many-to-one class="it.inform.w3.bean.Dominio"  name="codentdom"  not-null="true" fetch="join">
           <column name="codentdom" not-null="true"/>
        </many-to-one>

        <property name="cafwkfitt" type="string">
            <column name="cafwkfitt" length="8" sql-type="string" not-null="false"/>
        </property>

        <property name="cafwkfatt" type="string">
            <column name="cafwkfatt" length="30" sql-type="string" not-null="false"/>
        </property>

        
    </class>

How could i map this two table??? The column "codentitt" is a part of key of table ItemTypeProcessoConfigurazioneProprieta but the attribute "codentatt" is a many to one to table ItemTypeAttributo that has a primary key with 2 columns where 1 of these is "codentitt"

This map doesn't work.. which is the correct one?

thanks

What error are you getting? "Doesn't work" doesn't help us decipher your problem..

Your mapping is very similar to the one in section 23.4.2. "Composite key example", of the ref docs. Compare your mapping to that, maybe that will help.
