Nothing works!!!
For Gregory:
Application see new photo uploaded when I click on refresh button on
gwt browser implementation.
Maybe I have understanding problem.
Images uploaded necessarily go on public directory because client
don't have access to other directory on server or local machine, ok?
When application starting, it's copy all file present on public
directory and put it on public directory of gwt compilation output
(usually call com.package.modulename).
I think error probabilly is on UPLOAD_DIRECTORY path on server side.
Whats proper path for UPLOAD_DIRECTORY??
If I set UPLOAD_DIRECTORY= "images/album/" application give me an
error (resource not found or similar)...if I set
UPLOAD_DIRECTORY="src/com/webphotogallery/public/album/" I go into
error because this directory it's not seen by application when run,
but only when I click on reload button..
My idea are correct?
