This illustration shows a sample `ejb-jar.xml` file:

    <relationship-role-source>
       <ejb-name>EmpBean</ejb-name>
    </relationship-role-source>
    <cmr-field>
       <cmr-field-name>address</cmr-field-name>
    </cmr-field>

It also shows a sample `orion-ejb-jar.xml` file:

    <cmp-field-mapping name="address>
       <entity-ref home="AddressBean">
          <cmp-field-mapping name="address" persistence-name="addressPK" />
       </enetity-ref>
    </cmp-field-mapping>

There is an arrow from the `<cmr-field>` portion of the `ejb-jar.xml` example to the first and third lines of the `orion-ejb-jar.xml` example.
