I had the same issue.
Did you specify a schema in the `seam setup`? It would be the
hibernate.default_schema property in seam-gen/build.properties file.
thanks! I'll check that out (hibernate.default_schema) - I redid my "setup" and specified the schema and that worked. You'd think it would default to the "user", if not specified - but perhaps that may be too specific behaviour to Oracle and not other database vendors.
