Interoperability between the DB2 driver and the Derby server disappeared many years ago.
I don't think Derby 10.8 is anywhere old enough for things to work properly; I think the last serious testing of those configurations was back in the 10.2, 10.3 days (though my memory is fuzzy). However, if you got things to "mostly work", I'm sure the community would be quite interested to hear the details, and of course if you wanted to contribute patches to improve the Derby behavior in that configuration, they would certainly receive attention by the developers. bryan P.S. It's been years since I looked at the DB2 driver. Is it by any chance open source now?
