how to put audio to a java program?

I have the following code to put audio to an application that I am developing, the problem is that it sends me the following error

  

Exception in thread "main" java.lang.NoClassDefFoundError:   org / apache / commons / logging / LogFactory at   javazoom.jlgui.basicplayer.BasicPlayer. (Unknown Source) at   music.musica2. (musica2.java:12) at   musica.musica2.main (musica2.java:39) Caused by:   java.lang.ClassNotFoundException:   org.apache.commons.logging.LogFactory at   java.net.URLClassLoader.findClass (Unknown Source) at   java.lang.ClassLoader.loadClass (Unknown Source) at   sun.misc.Launcher $ AppClassLoader.loadClass (Unknown Source) at   java.lang.ClassLoader.loadClass (Unknown Source) ... 3 more

I do not know what I'm doing wrong, any ideas?

package musica;

import java.io.File;

import javazoom.jlgui.basicplayer.BasicPlayer;

public class musica2
{
  private BasicPlayer player;

     public musica2()
     {
      player=new BasicPlayer(); 
     }

    public void Play() throws Exception 
    {
     player.play();
    }

    public void AbrirFichero(String ruta) throws Exception {
      player.open(new File(ruta));
    }

    public void Pausa() throws Exception {
      player.pause();
    }

    public void Continuar() throws Exception {
      player.resume();
    }

    public void Stop() throws Exception {
      player.stop();
    }

    public static void main(String[] args) 
    {
    try {
          musica2 mi_reproductor = new musica2();
          mi_reproductor.AbrirFichero("c:/mi_archivo_de_musica.mp3");
          mi_reproductor.Play();
        } catch (Exception ex) {
          System.out.println("Error: " + ex.getMessage());
        }
   }

}
