I ran into similar problems some time ago.  The issue is that Java doesn't
support ".." directories when locating resources.

What you need to do is find some class in a parent directory (or create a
dummy one) and use it to load the resources.  In your case, create a class
called com.mycompany.ImageLoader and use it as follows:

jButton1.setIcon(new
ImageIcon(ImageLoader.class.getResource("myimages/myPicture.PNG")));

It does mean modifying JBuilder's generated code, but once you've done so
once JBuilder should leave it alone.

Actually, I think it does.  Here's some code that works.

Given the following directory

   ../projects
       /thisproject
         /src
           /images
             - logo.png
             ... a bunch of other icons
           /org
             /pf
               /utils
                 - ImageResources.java
                   ... a bunch of other classes


file: org.pf.utils.ImageResources

package org.pf.utils;

import javax.swing.*;
import java.awt.event.*;
import java.lang.reflect.*;

/**
  * <p>Title: ImageResource Util</p>
  * <p>Description: Central class for grabbing images.</p>
  * <p>Copyright: Copyright (c) 2003, 2004</p>

  */

public class ImageResources {

   public final static Icon smallLogo =
       new ImageIcon(
          ImageResources.class.getResource(
             "../../../images/small-logo.png"));

   public final static Icon largeLogo =
       new ImageIcon(
           ImageResources.class.getResource(
               "/images/large-logo.png"));


   private ImageResources() {
   }

   /** Just a small test program to ensure
    *  that the images are loadable.
    *
    * @param args String[]
    */
   public static void main(String[] args) {
     JFrame f = new JFrame();
     JPanel panel = new JPanel();
     f.getContentPane().add(panel, null);
     panel.setLayout(new BoxLayout(panel, 1));

     try {
       Class c =
           Class.forName(
               "org.pf.utils.ImageResources");

       Field [] fields = c.getFields();

       for (int i = 0; i < fields.length; i++) {
         panel.add(new JLabel(fields[i].getName(),
         (ImageIcon)fields[i].get(null), JLabel.HORIZONTAL));
         panel.add(Box.createVerticalStrut(16));
       }
     }
     catch (Exception ex) {
       ex.printStackTrace();
     }

     f.addWindowListener(new WindowAdapter() {
       public void windowClosing(WindowEvent e) {
         System.exit(0);
       }
     });
     f.pack();
     f.show();
   }

}

Note that if you don't get the above code to
work, check your directories.  Also, I made
some modifications from an existing class
that I use, notably the package structure.
So the "../../../" in the ImageResources
might be wrong.  But it might be right.
Make sure you do have the images in the
right place first.

What I do is to create a private member Icon variable which
is then usable in the Designer.  For instance, ...


public class AnExample {

   private Icon smallLogo = ImageResources.smallLogo;
   private Icon largeLogo = ImageResources.largeLogo;

   ...

}

Now, in the Designer, when you go to the "icon"
property of say a JButton, you will see

   <none>
   smallLogo
   largeLogo

in the drop-down list. Pick one and the Designer shows
the button with the icon on it ... that is, if you
have compiled the project in order to get the images
copied (deployed) into the /classes directory.

No need for messing around with paths.  And if
you use the "Resource Strings" Wizard on the
ImageResources class, you can even modify the
location (or internationalize) of your images
using .properties files.  For example, suppose
you need to show the choking symbol -- for
the US, you'd show an icon with arms crossed
over the chest, left-hand to the right side of
the neck, and vice versa for the right hand.
For the international sign, you'd show an icon
with arms raised, hands inverted and gripping the
neck from their respective sides.  In both
cases, the tongue would be out, and eyes
would be bulging.


Any smileys needed?

I'll have to check my code again.  I haven't touched that particular piece
of code since JDK 1.2 so the issue may be long dead.

I think that is the case.  I recall having problems using ".." some
time ago, but I have since tested it and found that it works.
