Stuck on playing wav file in java… Need some guidance

Question

I'm trying to play sound in java when a button is pressed. So I have something like the following:

public void playSound(File soundFile) {
    try {
        AudioInputStream stream = AudioSystem.getAudioInputStream(soundFile);
        AudioFormat format = stream.getFormat();
        DataLine.Info info = new DataLine.Info(Clip.class, format);
        Clip clip = (Clip) AudioSystem.getLine(info);
        clip.open(stream);
        clip.start();
    }
    catch (Exception e) {e.printStackTrace();}
}

Then I call the method in actionPerformed inside buttonListener:

playSound(new File("woow_x.wav"));

But it's throwing UnsupportedAudioFileException. Is this saying that .wav files are not supported? I confirmed that the wav file works so I don't know what the issue is. And I'm trying to do this without using sun. Please let me know how this is correctly done. Thank you.

The file's encoding is specified in its header to be 0x55 . I'm not sure exactly what 0x55 is, but I suspect it is mp3. Either way, it's not one of the encodings supported by Java.

For your purposes (and if the license allows it), you might use an audio editor to convert the file to a format that is supported. (These are enumerated by the static fields in AudioFormat.Encoding .)
