#1

Bom dia a todos, eu gostaria de desenvolver um mp3 player e um wav player para celular usando JME.

Só que eu executo dá erros:

Segue abaixo o código do wav player:

Obs: estou tentando executar o .wav a partir de um arquivo .jar. Uma coisa, tem maneira certa de criar o .jar ou posso usar o winrar?

package player;

import java.io.InputStream;
import javax.microedition.lcdui.Command;
import javax.microedition.lcdui.CommandListener;
import javax.microedition.lcdui.Display;
import javax.microedition.lcdui.Displayable;
import javax.microedition.lcdui.Form;
import javax.microedition.lcdui.StringItem;
import javax.microedition.media.Manager;
import javax.microedition.media.Player;
import javax.microedition.midlet.MIDlet;

public class WavPlayer extends MIDlet implements CommandListener {	

	public WavPlayer() {
		display = Display.getDisplay(this);
		
		// criamos o comando sair
		exit = new Command("Sair", Command.EXIT, 2);
		
		// criamos a tela principal
		screen = new Form ("Player");	    
	    
		screen.append(new StringItem("","Informalções do Player:\n"));

	    { // ---- memório total e livre ----
	    	
	    	Runtime runtime = Runtime.getRuntime(); 
		    memTotal = Long.toString(runtime.totalMemory()); 
		    memLivre = Long.toString(runtime.freeMemory()); 
	    	
		    screen.append(new StringItem("","Memória Total: " + memTotal + "b\n"));
		    screen.append(new StringItem("","Memória Livre: " + memLivre + "b\n\n"));
	    }  
	 
	    
	    { // player
	    	try {
	    		 audio = getClass().getResourceAsStream("Tarzan.wav"); 
	    		 player = Manager.createPlayer(audio, "audio/X-wav"); 
	    		 player.start(); 
	    	}
	    	catch(Exception e) {
	    		screen.append(new StringItem("","Erro:: " + e + "b\n"));
	    		System.err.println("Erro: " + e);
	    	}
	    }
	    
	    screen.addCommand(exit);
	    screen.setCommandListener(this);    
	} 

	protected void startApp() {  // método de iniciação da Aplicação
		 display.setCurrent(screen);
	} 

	protected void pauseApp() {
		
	}
	
	protected void destroyApp(boolean bool) {
		
	}

	public void commandAction(Command cmd, Displayable disp) {
		if (cmd == exit) {  
			destroyApp(false);
			notifyDestroyed();
		}
	}
	
	// ---- variáveis ----
	private Display display;
	private Form screen;
	private Command exit;
	private String memTotal, memLivre;
	private Player player;
    private InputStream audio;
}

o erro é o seguinte:
