Installation instructions?

[william-ferguson-au]

I'm trying to get nrjavaserial up and running on Windows10 but am not having much luck. Is there any special install routine that is required or is it enough to include the nrjavaserial.jar in the classpath?

The following app completes without finding any serial ports.

public class App {
    public static void main(String[] args) throws IOException {
        for(String s: NRSerialPort.getAvailableSerialPorts()){
            System.out.println("Available port: "+s);
        }
    }
}
