Java issues

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
at (/usr/lib/
Caused by: java.lang.ClassNotFoundException: .home.michael.Desktop.AirportUtilities.configurator.AConfig.jar
at java.lang.Class.forName(java.lang.String, boolean, java.lang.ClassLoader) (/usr/lib/
at java.lang.Class.forName(java.lang.String) (/usr/lib/
at (/usr/lib/

Any tips to make it open and not confuse me?

Hi there, first you will need to run it from the directory it is found in, and since it is (likely) an executable jar file, use the command below to start it:

cd /home/michael/Desktop/AirportUtilities/configurator/
java -jar AConfig.jar
That should get you off and running.
