I think it will work now without a patched jar. If printing
is on in the <sql> task it seems to break with most of
the JDBC drivers. I turned the printing off and all the
problems went away. But I will try to make sure.

This is going in now.

I'm not sure, but I will fix torque and add the option to
suppress default values so that the turbine schema doesn't
have to be changed.

The path is a problem ... the jetspeed people handle this with
the VariableResources class.

Any tips are good, I've haven't tried Hypersonic so
your experience with it helps me a lot. Thanks for
the info :-)

jvz.
