Hi,

Shop has a set of contacts. it is the many to many relationship.
i added an rel_obj_contact as relationtable which contains objid(shopid), contactid and relationtypeid.
ObjectContact is a compositeElement wrapping 1 contact and 1 relationtype.

The PROBLEM is, if i delete a shop, the relationship item in rel_obj_contact will not be deleted. (i want the relationship in my database deleted)

How can I implement it?


Code:
<Shop...>
      <set name="shopContacts"
             table="REL_OBJ_CONTACT"
             cascade="all"
          lazy="false">

         <key column="OBJID"/>

           <composite-element class="ObjectContact">
              
            <many-to-one name="contact"
                      column="contactid"
                      class="Contact"
                      cascade="save-update"/>
                     

            <many-to-one name="relationType"
                      column="relationid"
                       not-found="ignore"
                      class="RelationType"
                      cascade="save-update"/>

          </composite-element>
          
       </set>
...
</Shop>

Your mapping looks okay, so there may be a problem with the code. Are you modifying a Shop entity that you obtained from the current Session?

Note that this has nothing to do with cascades. The deletion of an item in the join table REL_OBJ_CONTACT is done when Hibernate does a Session.flush() and it notices that the collection has changed. This works because Hibernate replaces the original Set with its own Set implementation which tracks changes. It does this replacement when the entity is saved or when it constructs a new instance from query results.
