Thanks for that helpful background Kris.
Given that design it seems that jxDBCon might be a better model
for my needs. I'm trying to contact the authors to get some information
on the history and status of the project. (It seems to have been
abandoned some years ago.)
Meanwhile, I'd be delighted if anyone could suggest any other JDBC
driver development framework I could learn from. Or, else any other
open source JDBC driver with a good internal architecture.
Thanks!
Tim.
