Does anybody have experience with CMP entity relationships and mapping them to AS400 datasources?

I am working my way through the book and I have all examples to this point(chapter 7) working so I am sure datasource is configured and working. The one-to-one unidirectional and bidirectional examples worked perfectly, the third example is one-many unidirectional and this is where the problem starts.

Can anybody offer up what the jbosscmp-jdbc.xml file might need to look like for this example? All the EJBs delop without error but when I run client_71c I get an error that produces the following server log:
