Try making one a collection descriptor with getters and setters that
operate on only a single object in the collection and the other a
reference descriptor. It's not the most elegant solution, but it works
and is supported by OJB as is. I think in the next version of OJB, a
<inverse-foreignkey> should be added to the reference descriptor to
allow the FK column to exist in either table in a 1-1 relationship.
Try this...
Public class Customer {
protected List businessPartner;
public Customer() {
businessPartner = new ArrayList();
}
public BusinessPartner getBusinessPartner() {
return businessPartner.get(0);
}
public void setBusinessPartner(BusinessPartner bp) {
this.businessPartner.add(0, bp);
}
...
}
Then declare as a collection in repository.

Hallo Olli,
thanks for your reply, now it works better, but not as I want it.
What I want was a bidirectional 1:1 relationship but this one is only
unidirectional. I can get the BusinessPartner from the Customer but not
the otherway round.
Also the FK_CUST column in the DB is NULL but I'm not sure if I need
such a column, because in my opinion the key entry in the OJB_CUSTOMER
table should be enough!?
I hope you can help me with this issue, too ;-)
Thanks,
Stephan

here, field-ref should not be xml-content
but an attribute in the opening tag.
> </foreignkey>
> </reference-descriptor>
HTH,
