I have an internal tool written in java. It would be useful to get a little feedback on how much it is used by colleagues. A simple solution would be to have the application display an image which it fetches from a web hit counter like application and just look at how often the image is accessed.
So what I am looking for: a stand-alone application (i.e. no Apache modules, cgi scripts, etc), which serves one or a couple of static images and and can log accesses, preferably with as little as possible of support of everything else. Searching for "hit counter" gave little relevant, "lightweight http server" was more relevant, although mostly overkill still. Any suggestions?
