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.
