Vitali, you are awesome. I was able to pass in the java dataHandler using
JSNI, with an overlay for the SQLResultSet class as you suggested... and it
is working beautifully. Took me a minute to get my head around the overlay
concept, but I get it now, very cool.

Now, I only wish I could have html5 db support in the hosted mode browser.
I'm on OSX, and I'm guessing the hosted mode browser is firefox? I get the
same error in firefox, but safari supports it. Anyway to change hosted mode
browser to Safari? I searched, and find people talking about changing
browser but no solutions found.

Thank you very much.
Dean
