RE: [ojb-users] How define composite keys using OJB.

[Weaver, S. <Sw...@ri...>]

Thanks Thomas, 
I had originally come to that conclusion, but was getting weird query
results. 

The issue ended up being that I had forgot to add the
<PrimaryKey>true</PrimaryKey> to one of the 3 FieldDescriptors that were
PK's.  After fixing that, everything worked fine.

Thanks again,
Scott
