Vijai,
Are you using the Enterprise 4.x or 5.x product or webMethods B2B/IS 4.6/6.x platform? The ODBC Adapter mentioned is an Enterprise Adapter, not an B2B/IS Adapter.
The Sun ODBC JDBC Bridge is not a great option in any case due to issues with it running in multi-threaded environments [check out Sun’s site for more information].
You may find a driver option for MS Access at this site [it would have to be used with the WmDB package if you’re running B2B/IS]:
