Your jboss <ejb-relation> is incorrect. I strongly
suggest you read JBoss's JBoss Administration and
Development Guides available for free now at JBoss's
website. With a quick glance I saw multiple errors
and realized it would be simpler and more beneficial
to you if you read the manuals.
You have not specified the foreign keys and their
related primary key fields correctly. I strongly urge
you read the manuals. The information is presented
well enough at this point. For this problem you only
need to read the section on CMRs.
You should understand that XDoclet's @jboss.relation's
related-pk-field corresponds to an entity bean's
primary key field (the java code primary key field)
and that the fk-column references the actual
datasource's column name. Read the manual, it will
explain all of this and more.
Your jbosscmp-jdbc.xml should look something like the
following for a one-to-one unidirectional relationship
from Author to Image:
<ejb-relation>
<ejb-relation-name>Author-Image</ejb-relation-name>
<ejb-relationship-role>
<ejb-relationship-role-name>Author-has-Image</ejb-relationship-role-name>
<key-fields>
<key-field>
<field-name>id</field-name>
<column-name>author_id</column-name>
</key-field>
<key-field>
</ejb-relationship-role>
<ejb-relationship-role>
<ejb-relationship-role-name>Image-has-Author</ejb-relationship-role-name>
<key-fields/>
</ejb-relationship-role>
</ejb-relation>
Thanks.
