Upload directory

Nafise wrote

I've used upload controller; it places uploaded files in tomcat temp directory and obviously After tomcat shut down, temp directory would be cleaned. How can I change upload directory to another local directory or ftp address?

The idea is that temporary files are removed when the session for the user that uploaded the file expires. It is assumed that your application will copy those files to a more permanent directory or save them in a database, for instance when the user "saves" the form. If you don't, even if the files were not deleted, you would be left with a number of "random" temporary files in a directory that are not tied to any specific user.

Great.

It's going to be a little more complicated in this case. Your element
"logo" contains some base64, right? Then you will need to serialize it
to a temporary file (you can use for this the new improvements to the
file serializer; see:
http://www.nabble.com/New-feature%3A-Support-for-temporary-files-in-File-serializer-to14768186.html)
when you load the XML from eXist. Then you're in the same case as you
were before.

But note that the URL to the temporary file may work locally, but
won't work if someone is accessing your server remotely. In that case
you will need to change that with a URL that points back to your
server and serves that temporary file.
