David-
According to the spec, "interfaces should not be designated as
entities", and if you can't declare it as an entity, then you don't
have anywhere to specify its interface name.
The Kodo JDO layer on top of OpenJPA does support querying on
interfaces, though. I wonder if it would work if you did "select i
from com.somepackage.IData i". If that raises an error, can you post
the stack trace?

Hi everyone,
I've recently run into a bug in Kodo JDO that appears to be
occurring in
OpenJPA. I have a test case that fails in Kodo JDO, but I'm stumped
how
to port the test case to OpenJPA.
My test case has two data classes and one interface that each class
implements. SensorData and PublicData are the data classes and
IData is
the interface. The interface and classes are very simple.
What I need to do is query on the interface, and I don't know how
to do
it. I don't know how to annotate the interface or whether I
should. I
don't know how to write the query. A simple, "select i from IData i"
would be just fine if it worked.
Any suggestions?
Thanks,
David Ezzio
