I can't seem to connect to my localhost data but able to connect to
another computers data. I have dgw running as a service on my nt machine
and this hasn't given me any troubles until this morning (grr), when I
uninstalled some seemingly unrelated stuff from my machine. Since then,
I haven't been able to connect. I've reinstalled dgw and even jbuilder
with no luck. One weird thing, when i reboot, if I connect using an
installed java application that hits my datasource, it works fine. but
then when i open up jbuilder and run there the first time through it it
connects and begins to go run my queries, but then crashes giving me a
"connection reset by peer" error. After that, I can't connect either
from jbuilder or from the installed application that just worked (!).
Does anyone know whats going on with DataGateway/jbuilder ??. I've
stopped and started the service and still the same problem. I'm using
Jbuilder 2.01.

thanks.  --alex

one of the stack traces I got (and yes, dgw is running on the machine at
the time).:

  Have you tried 127.0.0.1 ??  I've seen situations where "localhost" 
would not work but the IP address for the localhost would.

    This error comes from the DGW server being unable to contact the 
database server after making a connection.  What is your backend..??
