How to get InputStream in jar file

Question

Could anyone give me a tip how I can play this sound file inside the application jar file?
I have this package: *{color:#0000ff}com.sikgraf.ui{color}*
with *{color:#ff6600}ArquivoMagneticoUI.class{color}* and {color:#ff6600}*applause.au*{color}
I am tyring to get the InputStream but It's being painful and so far no success
Here are the 3 ways I tried:
InputStream is = ArquivoMagneticoUI.class.getResourceAsStream("applause.au");
is = getClass().getResourceAsStream("applause.au");
is = this.getClass().getClassLoader().getResourceAsStream("applause.au");All them return:
java.lang.NullPointerException

        at com.sun.media.sound.WaveFileReader.getAudioInputStream(WaveFileReader.java:160)
        at javax.sound.sampled.AudioSystem.getAudioInputStream(AudioSystem.java:1094)What I am doing wrong?

Thanks for your reply, I just figured out using URL:
    public static void playSound(int index) {
        String files[] = {"applause.au", "cash_register.au", "ding.au", "donkey_1.au", "duck_1.au", "siren_2.au"};
        String sound = "som/" + files[index];
        try {
            URL url = ArquivoMagneticoUI.class.getResource(sound);
            AudioInputStream ain = AudioSystem.getAudioInputStream(url);
            AudioFormat format = ain.getFormat();
            if (format.getEncoding() != AudioFormat.Encoding.PCM_SIGNED) {
                format = new AudioFormat(
                        AudioFormat.Encoding.PCM_SIGNED,
                        format.getSampleRate(),
                        format.getSampleSizeInBits() * 2,
                        format.getChannels(),
                        format.getFrameSize() * 2,
                        format.getFrameRate(),
                        true);        // big endian
                ain = AudioSystem.getAudioInputStream(format, ain);
            DataLine.Info info = new DataLine.Info(Clip.class, ain.getFormat(), ((int) ain.getFrameLength() * format.getFrameSize()));
            Clip clip;
            clip = (Clip) AudioSystem.getLine(info);
            clip.open(ain);
            clip.start();
        } catch (LineUnavailableException ex) {
            //Logger.getLogger(ArquivoMagneticoUI.class.getName()).log(Level.SEVERE, null, ex);
        } catch (UnsupportedAudioFileException ex) {
            //Logger.getLogger(ArquivoMagneticoUI.class.getName()).log(Level.SEVERE, null, ex);
        } catch (IOException ex) {
            //Logger.getLogger(ArquivoMagneticoUI.class.getName()).log(Level.SEVERE, null, ex);
    }
