How to set MIDI out transmitter?

Hello,

I'm using a Java library called jMusic to create some sounds. I'm just trying it out for now so I've made this simple program. When I try to run it, I get the following exception:

run: Midi System Unavailable:javax.sound.midi.MidiUnavailableException: MIDI OUT transmitter not available BUILD SUCCESSFUL (total time: 2 seconds)

I guess I need a transmitter which, in turn, sets a receiver (right?) but, being very new to the whole sound in Java experience, I'm not really sure where to go from here.

Here is my little program:

package soundtesting;

import jm.JMC;
import jm.music.data.*;
import jm.midi.*;
import jm.util.*;
import javax.sound.midi.*;

public class SoundTesting implements JMC{


public static void main(String[] args) {
    Note note = new Note(C4, CROTCHET, MF);
    Phrase phrase = new Phrase();
    phrase.addNote(note);
    Part part = new Part();
    part.addPhrase(phrase);
    Score score = new Score(part);


    Play.midi(score);

}

}

Any help outputting some sound?

Thanks in advance,

Matt
