OpenJPA certainly should be able to handle interfaces -- see OpenJPAEntityManager.createInstance(). I don't see any tests of this method in the OpenJPA test suite, though.

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?
