Thanks Adam,
The error I get refers to "key-column='POSTAL_DEPOT_KEY'" and that
POSTAL_DEPOT_KEY is not the primary key for PostalPackage. So I changed it
to POSTAL_PACKAGE_KEY and it seemed to like that. I haven't tested it yet
though.
Also in weblogic-cmp-rdbms-jar.xml the relationships section does not
conform to the deployment descriptor as I know it. It does not have the
multiplicity elements etc, and it seems that only one side of the
relationship is defined. The following is the generated section for the
package-postalDepot relationship:
<weblogic-rdbms-relation>
<relation-name>package-postalDepot</relation-name>
<weblogic-relationship-role>
<relationship-role-name>one-postalDepot-has-many-packages</relationship-role
-name>
<column-map>
<foreign-key-column>POSTAL_DEPOT_KEY</foreign-key-column>
<key-column>POSTAL_PACKAGE_KEY</key-column>
</column-map>
</weblogic-relationship-role>
</weblogic-rdbms-relation>
Is this correct? I thought it should define the multiplicity of each side
of the relationship? And the <column-map> section looks odd too!

Your XDoclet tags look correct. I've used the exact same tags without any
problem. What is the exact output from the error message you are getting?
Also, in your data schema, make sure you have a POSTAL_DEPOT_KEY column
defined in the table for PackageBean. WebLogic will use this to map the
foreign key relationship between PackageBean and PostalDepotBean.

Subject: [Xdoclet-user] Many to 1 Unidirection Relationship
Hello,
I've tried several different combinations of tags to generate a many to 1
unidirectional relationship, but can't get it.
Say I have a two beans, a PackageBean and a PostalDepotBean, and many
packages can belong to one Depot. So I want the PackageBean to know which
DepotBean it belongs to but don't want the DepotBean to know which packages
belong to it.
The following is what I curently have as the relationship declaration in the
PackageBean
/**
* @return the postal depot for this package
* @ejb:interface-method view-type="local"
* @ejb:relation
* name="package-postalDepot"
* role-name="one-package-belongs-to-one-postalDepot "
* target-role-name="one-postalDepot-has-many-packages"
* target-ejb="PostalDepot"
* target-multiple="yes"
*
* @weblogic:column-map
* foreign-key-column="POSTAL_DEPOT_KEY"
* key-column="POSTAL_DEPOT_KEY"
*/
public abstract PostalDepotLocal getPostalDepot();
/**
* @param postalDepot the postal depot for this package
* @ejb:interface-method view-type="local"
*/
public abstract void setPostalDepot(PostalDepotLocal postalDepot);
POSTAL_DEPOT_KEY is the primary key of the PostalDepotBean.
This does not work as xdoclet complains that I need a primary key column
called POSTAL_DEPOT_KEY in the PackageBean.
How do I define the PackageBean as the 'many' side of the relationship?
Thanks
