EJB Relacionamento

Ola pessoal,
Estou com grandes dificuldades para fazer o relacionamento entre as tabelas abaixo, o motivo eh, o relacionamento que quero criar nao tem primary key.
Por exemplo:

Tenho as tabelas (e os Entity Bean de cada tabela):

Local:
local_id
local_origem
local_destino

Endereco:
endereco_id
local_geral
endereco_nm
endereco_ds

Em ejb-jar.xml:

  <ejb-relation >
     <ejb-relation-name>LocalOri-Endereco</ejb-relation-name>

     <ejb-relationship-role >
        <ejb-relationship-role-name>Endereco-Has-LocalOri</ejb-relationship-role-name>
        <multiplicity>Many</multiplicity>
        <relationship-role-source >
           <ejb-name>Endereco</ejb-name>
        </relationship-role-source>
        <cmr-field >
           <cmr-field-name>localori</cmr-field-name>
        </cmr-field>
     </ejb-relationship-role>

     <ejb-relationship-role >
           <ejb-relationship-role-name>LocalOri-do-Endereco</ejb-relationship-role-name>
        <multiplicity>One</multiplicity>
        <relationship-role-source >
           <ejb-name>Local</ejb-name>
        </relationship-role-source>
        <cmr-field >
           <cmr-field-name>endereco</cmr-field-name>
           <cmr-field-type>java.util.Collection</cmr-field-type>
        </cmr-field>
     </ejb-relationship-role>

  </ejb-relation>

Em jbosscmp-jdbc:

<ejb-relation>
  <ejb-relation-name>LocalOri-Endereco</ejb-relation-name>
  <foreign-key-mapping/>
  <ejb-relationship-role>
     <ejb-relationship-role-name>Endereco-Has-LocalOri</ejb-relationship-role-name>
      <key-fields/>
  </ejb-relationship-role>
  <ejb-relationship-role>          <ejb-relationship-role-name>LocalOri-do-Enderecos</ejb-relationship-role-name>
      <key-fields/>

  </ejb-relationship-role>
</ejb-relation>

Minha duvida eh no jbosscmp-jdbc, qual o key-field devo colocar e aonde.
Gostaria de fazer dois relacionamento nessa tabela:

  1. Local.local_origem = Endereco.local_geral
  2. Local.local_destino = Endereco.local_geral

Agradeco desde ja qq ajuda.
Fazendo o primeiro creio que o segundo e copy-paste.

Obrigado mais uma vez
Daniel
