Hi

The EJB 2.0 specification [10.3.2] says that: "An entity bean that does not have a local interface can have only unidirectional relationships from itself
to other entity beans. The lack of a local interface prevents other entity beans from having a relationship to it."

I have written a couple of very simple CMP entity beans namely
PersonBean and AddressBean and have established a unidirectional
relationship from PersonBean to AddressBean. The unit deploys
successfuly on JBoss if I write local interfaces for both of the PersonBean
and AddressBean but if I remove the local interface for the PersonBean I
can't deploy the unit anymore and get some errors.

The deployment descriptor is as follows (the unit does not have jboss
specific dds):
