The version posted at .JdbcFixtures was posted a few weeks before the 20041105 release of fitnesse. Unfortunately, those jdbc fixtures won't work with the 20041105 release. Here is a version (based on the code at .JdbcFixtures, but simplified a bit) updated to work w/ the current version of Fitnesse.
