why is my japplet displays gray block in browser after adding an image icon?

Question

My japplet is able to run normally in NetBeans environment, but shows only a gray block screen in my browser (Chrome, IE). But when I removed all the image icons from my japplet, it runs normally in the browser and I have totally no idea why. Need some guidance for this.

My japplet class content

public void init() 
{
    try { UIManager.setLookAndFeel("com.sun.java.swing.plaf.windows.WindowsLookAndFeel"); }

    catch(Exception ex) { System.out.println(ex); }       

    try 
    {
        java.awt.EventQueue.invokeAndWait(new Runnable() { public void run() { initComponents(); } });
    } 
    catch (Exception ex) { ex.printStackTrace(); }

    jlbReg.setIcon(new ImageIcon(getClass().getResource("/MyIcons/icon1.png"))); 
    jlbAnn.setIcon(new ImageIcon(getClass().getResource("/MyIcons/icon2.png")));
    jlbSubmit.setIcon(new ImageIcon(getClass().getResource("/MyIcons/icon3.png")));
    jlbForum.setIcon(new ImageIcon(getClass().getResource("/MyIcons/icon4.png")));
}

My html content

<APPLET codebase="classes" code="MyJApplet.class" width=1150  height=1000></APPLET>

Answer 1

Your applet can't find the images in the jar file. Wait a minute - that's because you're not using a jar file. You need to use a jar file.
