We have the same environment and simply put a filter on the image web app to
catch *.jpg, then your main app doesn't have any logic to worry about, or
even "pre-fetch" images every time which would be a HUGE waste of resources.

That is what I'd like to do.   Have an image which is rendered in the case
when the defined image cannot be loaded.  the problem I have is that our
database record says that an image should exist, but the
manufacturer/supplier didn't provide it to us... thus I need a way to check
if that image does exist to test that condition.


ps - these images are maintained by a second webapp that is on a different
web server all together due to space requirements.  so i have to do testing
via a HTTP request or something i would think, no?

Just curious but why not just manually make this file once and return it
when a real image is not found on disk?  Why bother creating one on the
fly every time?  Is it different from request to request?

We had done something similar.  We created a static image file on disk
and return that when a real one is not available.  I think we used a
struts condition if tag testing if a real one exists otherwise use the
URL to not found image.

I'm curious if anyone has used or knows of an open-source image
rendering servlet that permits rendering a "no image found" image file
if the referenced image to be rendered does not exist on disk.
