Cannot comment on what you are doing wrong without looking into the
code. However I see no need for setUrl on server side. You should have
a "Servlet" that will parse the parameters, read the appropriate image
file(either file system or db or any doc mgmt system for that matter),
set a proper content type and just spit out the byte stream.
>From the client just call this servlet with appropriate params for it
to retrieve the image. In essence:
Image img = new Image();
img.setUrl("/servlet?photoId=39934&width=50");
