Hi,

I have a simple many-to-many unidirectional relationship that I'm trying to set up, and I keep getting the following exception:

org.jboss.deployment.DeploymentException: Both roles of a relation-table mapped relationship must have key fields: ejb-relation-name=Department-Item

Here are the relevant parts of my DD:


<![CDATA[No Description.]]>

<local-home> com.paperandpunch.persist.catalog.ejb.ItemLocalHome
</local-home>

com.paperandpunch.persist.catalog.ejb.ItemLocal

</relationship-role-name>
Many
<relationship-role-source>
<ejb-name>Item</ejb-name>
</relationship-role-source>
</ejb-relationship-role>
</ejb-relation>

My PK classes are pretty standard wrappers for a unique identifier (which is itself a wrapper for a byte array).

I've tried searching through the forums, on the net, and in the docs to no avail. What I have seems to be right. Am I missing something?

Thanks for the help!
