Title: Determining if an image exists
Hi all,

Just wondered if anyone has a simple approach to use Java in WebObjects to determine if an image (or file) exists at a URL.

What I’m doing is fairly simple, I want to display up to 4 images which have dynamic URL’s.  I want to check first if the image (URL) actually exists on the web server.  If not, I don’t want to display it.

Any suggestions?

Kind regards,
David.
