The problem is that your image name is "image.jpg" and therefore is
expected to exist in the same directory (or namespace, actually) as the
servlet. Thus, the url of the image is "http://.../servlet/image.jpg"; --
and the /servlet/ namespace is, by definition, a java class. Therefore,
not found!
Change the source url of the image to be correct:
out.println(request.getContextPath()+"/image.jpg");
