From: Peter T Mount <peter@retep.org.uk>

This implements some of the JDBC2 methods, fixes a bug introduced into the
JDBC1 portion of the driver, and introduces a new example, showing how to
use the CORBA ORB thats in Java2 with JDBC.

The Tar file contains the new files, the diff the changes to the others.
CHANGELOG is separate as I forgot to make a .orig ;-)
