  | I had this problem. It 's that you must understand the way to think when 
you describe your relations.
  | 
  | Here is something that will help you :
  | 
  | =================================================
  | <!-- Company-Division -->
  |  <ejb-relation>
  |     <ejb-relation-name>Company-Division</ejb-relation-name>
  |      <foreign-key-mapping/>    
  |       <ejb-relationship-role>
  |         
<ejb-relationship-role-name>Company-is-in-Division</ejb-relationship-role-name>
  |             <key-fields/>
  |              
  |          </ejb-relationship-role>
  |       
  |       <ejb-relationship-role>
  |             
<ejb-relationship-role-name>Division-has-Companies</ejb-relationship-role-name>
  |                     <key-fields>
  |                       <key-field>  
  |                             <field-name>id</field-name>
  |                             <column-name>division_id</column-name>
  |                     </key-field> 
  |             </key-fields>                           
  |       </ejb-relationship-role>   
  |  </ejb-relation>
  | ================================================ 
  | 
  | You describe the field name of the EJB from the ONE side of the relation 
that correspond to the column foreign key of the table in the MANY side of the 
relation.
  | 
  | Hope this help. ;o)

This is not working for me because i have a composite primary key in both sides.
