CMR - with composite key

[lameguy]

I'm going over this article on CMR http://technology.amis.nl/blog/index.php?p=90&page=3. The following code demonstrates how XDoclet is used to establish relationship between two entity beans:

 ... other stuff ...
 /**
 *
 *
 * @ejb.interface-method
 *
 * @ejb.relation
 * name="bibliography-may-contain-article”
 * role-name="BibliographyToArticle”
 * cascade-delete="yes”
 * target-cascade-delete="yes”
 * target-role-name="ArticleToBibliography”
 * target-ejb="Article”
 *
 * @jboss.target-relation
 * related-pk-field="publicationID”
 * fk-column="publication_id_fk”
 */
 public abstract ArticleLocal getArticle();
 ... other stuff ...

My question is, "related-pk-field" is a single field primary key, what if my primary key is a composite key?

Thanks in advance.

it will be the class of the composite primary key, database will store it as BLOB
