Jim,
Thanks for the quick response. I'm using 1.4 and I've
gotten 1:1 to work. I think my problem may be what
you mentioned about a non-standard CMR field in
ejb-jar.xml. What are you talking about exactly?
In the <relationship> tag? Here is my relationship
area again:
<ejb-relation>
<ejb-relation-name>EdiFile-EdiEnvelopes</ejb-relation-name>
<ejb-relationship-role>
<ejb-relationship-role-name>EdiFile-has-EdiEnvelopes</ejb-relationship-role-
name>
<multiplicity>one</multiplicity>
<role-source>
<ejb-name>EdiFileEJB</ejb-name>
</role-source>
<cmr-field>
<cmr-field-name>envelopes</cmr-field-name>
<cmr-field-type>java.util.Collection</cmr-field-type>
</cmr-field>
</ejb-relationship-role>
<ejb-relationship-role>
<ejb-relationship-role-name>EdiEnvelopes-belongsto-EdiFile</ejb-relationship
-role-name>
<multiplicity>many</multiplicity>
<role-source>
<dependent-name>EdiEnvelope</dependent-name>
</role-source>
<cmr-field>
<cmr-field-name>ediFile</cmr-field-name>
</cmr-field>
</ejb-relationship-role>
</ejb-relation>
