This is with the same installation?
I have not worked with Firebird, so these are generic hints.
Make sure that you have the correct jdbc version for your cocoon
binary. Cocoon comes in a jdbc2 and jdbc3 flavour (jdbc2 is pre j2se
1.4 and jdbc3 is post j2se1.4). If your firebird driver is only jdbc2
and you want to install it in a jdbc3 environment this will probably
break.
Look into the libs directory, some jars will have a vm14 or vm13 in
their filename to determine the cocoon version.

Switch the core log level to debug and see what happens upon
startup. The driver should get loaded during normal initialization IOW
no need to request a page. Avalon excalibur will try to send a test
query to firebird. Look for it in the logs and post the result
here. Maybe that will shed some light on the issue.
