NetBeans getting resource inside JAR file?

I have been trying to include some images and sounds in my Netbeans Java project and I have searched all over google looking for answers all of which I have tried and implemented but some play the audio file correctly when running it inside Netbeans but not when its actually built as a JAR file.

I am struggling to play a sound when executing the JAR File. As i understand it, the packages/folders inside the project are compiled and built into the JAR file.

Can anyone point me in the right direction as to how I correctly get a resource?

My code is as below:

public void SND_REQUEST() {
    AudioInputStream clipNameAIS;
    Clip clipNameClip = null;
    try {
        clipNameAIS = AudioSystem.getAudioInputStream(getClass().getResourceAsStream("/Sounds/Cat.wav"));
        clipNameClip = AudioSystem.getClip();
        clipNameClip.open(clipNameAIS);
    } catch (Exception e) {
        JOptionPane.showMessageDialog(null,"Request Button Sound Not Working");
    }
    clipNameClip.setFramePosition(0);
    clipNameClip.start();
}

UPDATE - 22:45:

It seems to work when running inside Netbeans, but not in the executable Jar file. I have tried both ways, ill post images: The file is certainly in ther, thanks for the help on that 1 Nik.

Updated code:

   public void SND_REQUEST() {
        AudioInputStream clipNameAIS;
        Clip clipNameClip = null;
        try {
            clipNameAIS = AudioSystem.getAudioInputStream(getClass().getResourceAsStream("/overtimesystem/Sounds/Cat.wav"));
            clipNameClip = AudioSystem.getClip();
            clipNameClip.open(clipNameAIS);
        } catch (Exception e) {
            JOptionPane.showMessageDialog(null,"Request Button Sound Not Working");
        }
        clipNameClip.setFramePosition(0);
        clipNameClip.start();
    }

Result:

UPDATE - WORKS::

AHH, FOUND THE ISSUE, Thanks for your help. Didnt think of passing the E.printstack trace in a JOptionPane msgbox lol :) It seems i needed the BufferReader for it to stream correctly. Also the path is correct. Please see my updated code which works for the project :) THANKS AGAIN!!!

public void SND_REQUEST() {
    AudioInputStream clipNameAIS;
    Clip clipNameClip = null;
    try {
        InputStream audioSrc = getClass().getResourceAsStream("/overtimesystem/Sounds/Cat.wav");
        InputStream bufferedIn = new BufferedInputStream(audioSrc);
        AudioInputStream audioStream = AudioSystem.getAudioInputStream(bufferedIn);

        clipNameClip = AudioSystem.getClip();
        clipNameClip.open(audioStream);
    } catch (Exception e) {
        JOptionPane.showMessageDialog(null, e);
        return;
    }
    clipNameClip.setFramePosition(0);
    clipNameClip.start();
}

  • Can anyone point me in the right direction as to how i correctly get a resource?

    Presuming the resources are within the created jar file, you can define the path as absolute relative to the package root: 

    clipNameAIS = AudioSystem.getAudioInputStream(getClass().getResourceAsStream("/overtimesystem/Sounds/Cat.wav"));

    Note the / at the beginning, defining the path as absolute (relative to the package root). You can also define a relative path (relative to the calling class). For instance, if the calling class is within the /overtimesystem/Images/ package, you can access the resource with ../Sounds/Cat.wav
