Hibernate version: 3.3.1

Mapping documents:
Code:
   <class name="model.Dostawca" lazy="false" table="DOSTAWCA">
      <id name="id" column="DOSTAWCA_ID">
         <generator class="native" />
      </id>
      <property name="nazwa" />
      <property name="miasto" />
      <list name="polprodukty"  cascade="all,delete"  table="DOSTAWCA_POLPRODUKTY" lazy="false" inverse="false">
         <key column="ID" />
         <index column="idx" />
         <one-to-many class="model.Polprodukt" />
      </list>
   </class>

   <class name="model.Polprodukt" lazy="false" table="POLPRODUKT">
      <id name="id" column="POLPRODUKT_ID">
         <generator class="native" />
      </id>
      <property name="nazwa" />
      <property name="symbol" />
      <property name="stan" />
      <many-to-one name="dostawca" class="model.Dostawca" column="DOSTAWCA_ID" not-null="true"  insert="false" update="false"/>
   </class>



Code between sessionFactory.openSession() and session.close():
Code:
        Session session = sessionFactory.getCurrentSession();
        session.beginTransaction();       
        session.delete(o);
        session.getTransaction().commit();
