Don't know when/if the HP e3000 Web Starter Kit 2.0 will become
available on CD in the US (it seems to have made it to the CD with
"proceedings" from the recent Amsterdam/NL event in Europe ;-)
but you might find it useful to checkout the "online preview"...

Under "Java Tips" there are a few JDBC examples, under "Web Kit"
you can find a collection of "ready-to-run" material (and also
a copy of the 6.0 Express-1 JDBC files ;-)

PS... You might also find JDBC (to TurboImage, not Image/SQL) at
Minisoft and ADBC (pure Java) at AdvNetSys.com as far as I recall.
