java.io.FileNotFoundException when java program start from cmd of runnable jar

Question

i have a card game project that works fine untill i use eclipse to open it up.

if i try to export it to a jar file or launch it from cmd, i keep having java.io.FileNotFoundException whenever i try to acces to folders or files.

For example i have a AudioManagert class that plays the resource giving his path as string.

this is working if i launch the program from eclipse, it doesn't from cmd.

Another example is when i try to load an image to create a new ImageIcon

new ImageIcon(getClass().getResource("/src/controller/resource/account.jpg"));

this would work on eclipse, not from cmd

how can i fix this problem? is there something to do with the use uf the path as a string?

here my AudioManager class method play()

public void play(String filename) {

        try {
            
            InputStream in = new BufferedInputStream(new FileInputStream(filename));
            AudioInputStream audioIn = AudioSystem.getAudioInputStream(in);
            clip = AudioSystem.getClip();
            clip.open(audioIn);
            clip.start();
            
        } catch (FileNotFoundException e1) {
            e1.printStackTrace();
        } catch (IOException e1) {
            e1.printStackTrace();
        } catch (UnsupportedAudioFileException e1) {
            e1.printStackTrace();
        } catch (LineUnavailableException e1) {
            e1.printStackTrace();
        }
    }

here my call from the program too it


                                AudioManager.getInstance().play("./src/resource/sposta.wav");

this works on eclipse, not on cmd

i add the image of where my audio and image resource are stored inside my project....
