Images created in servlet are in black and white

Sat, 6 Nov 1999 18:55:01 -0800 

I am using acme's GifEncoder to dynamically create a chart in gif format.  I can get 
the image to be created, but it is always in black and white.  It seems that it does 
not work in true color, but when I switch to 16-bit color it seems to work.  How do I 
get this to work in true-color mode?

Here is an example of the method that I am using:

public void doGet(HttpServletRequest request, HttpServletResponse response)
{
  OutputStream out = response.getOutputStream();

  Frame frame = new Frame();
  frame.addNotify();

  Image image = frame.createImage( 100, 100 );
  Graphics graphics = image.getGraphics();
  graphics.setColor( Color.red );
  graphics.drawOval(0, 0, 99, 99);

  response.setContentType( "image/gif" );

  GifEncoder encoder = new GifEncoder( image, out );
  encoder.encode();
  out.flush();
}
