Hi,
I had a problem that was throwing the same error as the one you are getting
not so long ago. The first thing I was told to check was that the files
were all in the correct locations (jars and servlets) and that they were all
fully accessible (read, write, execute etc...).
In my case I had already done all this with no luck. It took me a while to
figure this out, but my boss had failed to configure our firewall properly
and allow connections from our web server to my development database box.
One of my servlets was attempting to create a connection in init() and being
blocked by the firewall. This caused the same error as the one you are
getting.
