Mapping of a Class containing a subClass

Hello,

I have a Child Class with some attributes.
This Child Class is an attribute of a Parent Class.
Quite simple ;-)

I'd like to make reference to an attribute of the Child Class in the mapping of my Parent Class, without having to use association.

Can I make something like this ?

Code:

<hibernate-mapping package="com.cwsoft">
   <class name="Parent" table="TAD01">
      <id name="entity" type="string" column="CODETT">
         <generator class="assigned"/>
      </id>
      <property name="enfant.entityType" column="TYPETT" type="string" />
    </class>
</hibernate-mapping> 

Thanks in advance.

You can use component:

Code:

<hibernate-mapping package="com.cwsoft"> 
   <class name="Parent" table="TAD01"> 
      <id name="entity" type="string" column="CODETT"> 
         <generator class="assigned"/> 
      </id> 
      <component name="enfant" class="Child" >
          <property name="childProperty" type="integer">
              <column name="prop1" sql-type="integer"/>
          </property>
          <property name="childProperty2" type="string">
              <column name="prop2" sql-type="varchar" length="32"/>
          </property>
      </component>
    </class> 
</hibernate-mapping>
