Re: [Hibernate-devel] Please help with 1:n relationship

Hi Marco. Try the following:

<hibernate-mapping>
  <class name="com.mticket.Client" table="Client">
    <id name="clientId" type="long">
      <generator class="cirrus.hibernate.id.HiLoGenerator"/>
    </id>
    <property name="name"/>

    <set role="besteld" readonly="true">
        <key column="clientId"/>
        <one-to-many class="com.mticket.Order"/>
    </set>
  </class>

  <class name="com.mticket.Order" table="order">
    <id name="orderid" type="long">
      <generator class="cirrus.hibernate.id.HiLoGenerator"/>
    </id>
    <property name="description"/>
    <many-to-one name="Client" column="clientId" class
="com.mticket.Client"/>
  </class>
</hibernate-mapping>


For a bidirectional association, one (many-valued) end must be marked
read-only, telling hibernate to use the other end for updating persistent
state. Also the key column of the many-valued end must match the column of
the single-valued end. Hope that makes sense....

peace
