I suspect you are having the same problem we just had. You need to add the jar files for the database drivers in the following way:
1. Create a folder in the project and copy the database driver jar files to it
2. Add these files to the project build path (do NOT use the add external jar, use the add jar)
3. Now create the mapping config and the console config. When you create the console config the path to the database driver jar file should show up automatically in the config screen
