JDeveloper Unilateral relationship ejb-jar.xml verifying error

Question

I am huge difficulty with tables that have relationships mapping in one direction (unilateral).
If I give you a really basic scenario of table Emp which has Employee information and a Dept_no foreign key. I also have a table Dept which has department info and includes it's primary key of Dept_no.
When dragging and dropping tables from the Oracle Database onto the UML Diagram (OC4J container), the relationships automatically configure as bilateral. The ejb-jar.xml builds and the verifying Enterprise Beans verifies OK. If I select the relationship on the diagram and change it to be unilateral from Employee -> Department, it will still compile the EJB related source, but the ejb-jar.xml file will no longer verify the Enterprise Beans.
Now there have been a million ways that I have tried to get this simple example to work.
Here's my ejb-jar.xml and the orion-ejb-jar.xml:

that's probably all the relevant information.
As I said if I can't map relationships unilaterally from Oracle tables, then that is a huge issue for our project.
Any Help, would be fantastic - THANKYOU.
