Playing WAV files

[01010011]

Hello,
I am trying to figure out how to play .WAV files in my Java program. Here is the code. I get no errors when I compile but no sound plays. I placed the wav file in the same directory as my java and class files. I also tried to compile through the command line, passing the name of the file as the argument. I also instantuated my Sound class in the main of my driver program - Sound sound = new Sound("nightingale2.wav"); . Not sure what I did wrong. Any assistence will be greatly appreciated!

import java.io.*;
import javax.sound.sampled.*;
import javax.swing.JOptionPane;

public class Sound
{
	
	File soundFile;
	public Sound( String file)
	{
		soundFile = new File(file);
	}
	
	public void play()
	{
		try
		{
		
			AudioInputStream ais = AudioSystem.getAudioInputStream(soundFile);
			AudioFormat format = ais.getFormat();
			JOptionPane.showMessageDialog(null, "Format: " + format);
			DataLine.Info info = new DataLine.Info(SourceDataLine.class, format);
			SourceDataLine source = (SourceDataLine) AudioSystem.getLine(info);
			
			source.open(format);
			source.start();
			int read = 0;
			byte[] audioData = new byte[16384];
			while (read > -1)
			{
				read = ais.read(audioData, 0, audioData.length);
				if (read >=0)
				{
					source.write(audioData, 0, read);
				}
				
			}
			source.drain();
			source.close();		
			
	}catch (Exception exc)
	{
		JOptionPane.showMessageDialog(null, "Error: " + exc.getMessage());
		exc.printStackTrace();
	}
	System.exit(0);
}
public static void main( String [] arguments)
{
	if (arguments.length > 1)
	{
		JOptionPane.showMessageDialog(null, "Usage: Java Speaker Filename");
		System.exit(-1);
	}
	Sound sound = new Sound(arguments[0]);
	sound.play();
}
}
