The schema is called PBTEST and contains more than 40 tables and I've also set the default_schema property via Seam setup (to avoid generating against system tables). I've just tried it against 1.1.6.GA and generation still fails, with the same problem. Is there anyway I can tell seam-gen which specific tables to generate against to discover which table its failing on?
