Thanks David, there are a few there that need furthur investigation.

Possibly not. I was hoping there was something 'in the middle' of 'plain
JDBC' and full blown cmp2 that has passed me by.

Whilst cmp2 does seem to be overkill for what we need, it does have the
benefit that we do have experience with it, unlike the other frameworks. If
we were just using Firebird, we would have probably gone with 'just' JDBC and
SQL, but adding a second database engine into the mix, and things grow (two
lots of metadata to develop maintain, two sets of SQL statements etc.)
