Java Applet JProgressBar not showing

Hello guys. I know that this is not about games, but I’m stuck as hell. Tried on stackoverflow, noone knows how to help.

I can’t make the JProgressDialog visible. I have tried even with Jlabels - there are invisible too. The only thing that I can draw is a Button. I will post my init() method, please, have a look:

public class StartingClass extends Applet implements Runnable, KeyListener {

	// dafuq
	private static final long serialVersionUID = 1L;
	
	private Player player;
	private Image image, background;
	private Graphics second;
	static Container pane;

	private BackgroundAnimation bAnimation1 = new BackgroundAnimation();
	private BackgroundAnimation bAnimation2 = new BackgroundAnimation();
	private ArrayList<Missile> missiles = new ArrayList<>();
	private ArrayList<Blast> blasts = new ArrayList<>();
	public static int NUM_OF_MISSILES = 3; // missiles in each wave (increments by level)
	public Random randomY = new Random(); 
	public Thread gameloop;
	public boolean game_running = false;
	private JProgressBar healthBar;
	private Button button;
	private boolean check = false;
	private JLabel message;
	
	@Override
	public void init() {
		
		setSize(Constants._Screen_Width, Constants._Screen_Height);
		//setBackground(Color.BLACK);
		setFocusable(true);

		
		setName("witam");
		try {
			background = ImageIO.read( ClassLoader.getSystemResource("data/background.png"));
		} catch (IOException e) { e.printStackTrace(); }
		
		bAnimation1.setFrames(background);
		bAnimation1.setXY(0, 0); // first animation is in the left corner
		bAnimation1.setDelay(5);
		bAnimation2.setFrames(background);
		bAnimation2.setXY(1024, 0);
		bAnimation2.setDelay(5);
		player = new Player(300, 300);
		gameloop = new Thread(this);


	    healthBar = new JProgressBar(0, 100);
	    healthBar.setValue(0);
	    healthBar.setStringPainted(true);

	     message = new JLabel("Beginning work!");

	    add(healthBar);
	    add(message);
	  
		addKeyListener(this);
	
	}

Here is a whole class: http://pastebin.com/9j2nC034
I didn’t post whole here cause it’s probably not needed.

If there is someone experienced, I would be thankful. Im sitting here for 3 hours and did NOTHING.
