Just a thought. Have you tried to run it from the terminal?

example.
usr/lib/jvm/jre-1.6.0-sun/bin/java -jar %f
(Set the path according to where Java is located on your system)

Also try
sudo chmod +x nameofapp.jar

or

$>java -jar [nameofapp.jar]

I work more in windows environments than Linux and have not tested the library in Linux. As I mentioned in the library thread @jmon may have tried it.

What I believe to be happening is one of the following:
1. Not finding the NIC.
2. Not finding the MAC address for the NIC
3. Taking the wrong NIC.
4. Try to run the jar as root.
