try {
System.out.println("Setting device to be discoverable...");
local = LocalDevice.getLocalDevice();
local.setDiscoverable(DiscoveryAgent.GIAC);

Hello,
Do you have the javax.bluetooth api on your computer and in your classpath.It is throwing that exception because it cannot find the api. That looks like the problem to me.
