Yes CornedBee is correct. Sun says the following......

"Most ODBC 2.0 drivers should work with the Bridge. Since there is some variation in functionality between ODBC drivers, the functionality of the bridge may be affected. The bridge works with popular PC databases, such as Microsoft Access and FoxPro."

Im assuming by this statement that is would be better to get a specific driver rather than use the JDBC-ODBC bridge.

Here is the main page for the JDBC Data Access API technology.
