public class DemoGradientService

extends BaseGradientService

This is a demonstration extension of BaseGradientService. It returns three documents. One is a normal SVG document, returned via XMPP. One is a very nice SVG map (courtesy of the Andreas Neuman and the Batik project) that is loaded via HTTP One is a rectangles document that is updated over time by the server, and can send messages from ECMAScript back to the server.
