Uploading Images - Refresh Directory
Looking for some help - I am using DWR (ajax) to upload image files to my web
app.
The app is running on Tomcat v6.0.
I'm putting the files into a directory in WebContent\images or
WebContent\images\<sub directories>
When I upload the images, I then want to display them on my page. heres the
problem.
Even if I reload the page, the images will not appear on the page untill I
go into the eclipse IDE and "REFRESH" the WebContent or Images directory.
Any suggestions as to how I can get around this?
Thanks!

Is that directory inside the deployment directory of your webapp? Don't
do that!

What does REFRESH do in Eclipse? Does it re-deploy/reload the webapp? If
so, then you're hitting Tomcat's directory-caching behavior which makes
it difficult to put new files into the deployment directory while Tomcat
is running. Again, don't do that!

Put your files somewhere else, and map a URI in your web application to
a servlet that can fetch the files (and/or directory listings) from that
other directory.
