I am trying to use configurator to change the settings on my Airport Extreme Base Station, and installed java packages through synaptic.

michael@ubuntu:~$ java /home/michael/Desktop/AirportUtilities/configurator/AConfig.jar
Exception in thread "main" java.lang.NoClassDefFoundError: .home.michael.Desktop.AirportUtilities.configurator.AConfig.jar

That should get you off and running.

thanks
