driver not found exception for servlet

attempting to run an MS Access database through a servlet using jdbc:odbc with a dsn of Intranet (pointing to the database located in jigsaws www directory):

HTTP/1.1 100 Continue Date: Tue, 23 Feb 1999 22:19:20 GMT Server: Jigsaw/2.0.1 could not load database driver

any help with this, and database use for jigsaw would be much appreciated
