Here is the initialization code for the applet.:

  //Component initialization
  private void jbInit() throws Exception {
    component1 = Box.createGlue();
    jLabel1.setDebugGraphicsOptions(0);
    jLabel1.setMinimumSize(new Dimension(700, 500));
    jLabel1.setIconTextGap(4);
    jLabel1.setText("");
    Icon icon = new ImageIcon( "sunset.jpg" );
    jLabel1.setIcon(icon);
    xYLayout1.setWidth(800);
    xYLayout1.setHeight(600);
    this.setLayout(xYLayout1);
    this.add(jLabel1,  new XYConstraints(17, 23, 753, 548));
  }

Although I added several jpeg and gif files to the project, and they appear
in the dropdown list for the icon of jLabel1, selecting one of them does
virtually nothing.  So I added two lines of code:

    Icon icon = new ImageIcon( "sunset.jpg" );
    jLabel1.setIcon(icon);

Still no joy.  It seems that no matter what I try, I can't get these images
to display within the applet.  (NB: When the project is done, the image will
need to go into the same jar as the applet.)

What do I need to do to get this working (both from within JBuilder
9(personal) and from within a jar)?

Thanks,

Ted

I would select the image file from the icon property drop down list and make
sure that the project is compiled. The way you are specifying it below, you
are looking for a file relative to the working directory.  Reading files is
a no no  in an applet, but that is not why the designer is not showing the
image. It just cannot find it when you speicify it that way. (JBuilder's
working directory is not your projects working directory). If you put the
image file in the same directory as the java file that will be using it, and
add the file to the project, the designer will be able to reference it with
an URL releative the the class that is using it, and be able to find it.
