Hey guys,
I've the following problem. I've got one Java-Class name Ausleihe with three primary keys from three different tables.
Now I dont't know how I can get the reference in the xml file for id. in the moment i have this code. And I need the two references between the id tags. Does anyone know how to resolve my problem.

<hibernate-mapping package="de.htwberlin.bv.domain">
<class name="Ausleihe" table="Ausleihe" lazy="false">
<id>
<many-to-one name="nutzer" column="AUSWEISNR" insert="false" update="false" class="de.htwberlin.bv.domain.Nutzer"/>
<many-to-one name="exemplar" column="EXEMPLARID" insert="false" update="false" class="de.htwberlin.bv.domain.Exemplar"/>
</id>
<property name="anzahlVerlaengerungen" column="ANZAHL_VERLAENGERUNGEN" type="integer"/>
<property name="ausleihdatum" column="AUSLEIHDATUM" type="date"/>
<property name="erwartetesRueckgabedatum" column="ERWRARTETES_RUECKGABEDATUM" type="date"/>
<property name="gebuehr" column="GEBUEHR" type="big_decimal"/>
<property name="tatsaechlichesRueckgabedatum" column="TATSAECHLICHES_RUECKGABEDATUM" type="date"/>
</class>
</hibernate-mapping>
