il programma in compilazione emette i suoni desiderati!!ma quando creo il jar, non si sente niente e mi da questi warning!! come posso risolvere??

con che cosa stai compilando?

con netBeans!! da quello ke ho capito si tratta di qualche classe deprecata o qualcosa di simile!! e non viene aggiunta alla compilazione!!
ho cmq trovato un'altra soluzione per i suoni:

package MU;
import java.net.*;
import javax.sound.sampled.*;
import javax.swing.JOptionPane;

/**
 *
 * This class plays in a loop a wav audio file.
 *
 * @author Valerio Siviero - valerio.s@live.it
 *
 */
public class audio implements Runnable {

	private URL wavFile;

	private boolean isRunning = true;

		public audio(URL wavFile) {
			this.wavFile = wavFile;
		}


	public void play() {
		new Thread(this).start();
	}


    @SuppressWarnings("empty-statement")
	public void run() {

		try {
				Line.Info linfo = new Line.Info(Clip.class);
				Line line = AudioSystem.getLine(linfo);
				Clip clip = (Clip) line;
			    AudioInputStream in = AudioSystem.getAudioInputStream(wavFile);
			    clip.open(in);
			    clip.start();
			    while(clip.getFramePosition() < clip.getFrameLength()) ;
		} catch(Exception e) { JOptionPane.showMessageDialog(null,e.getMessage()); }

    }
	
    public void setRunning(boolean isRunning) { this.isRunning = isRunning; }

}

e poi nel programma:

new audio(getClass().getClassLoader().getResource(canzone.wav)).play();

ke ho preso dal programma "vEffect" di VaLeRiO
