File Uploader
Hello
I want to easily upload files to my web server, without the use of annoying web forms. So far, I have created a drag and drop application that I can drag files onto, and information of the corresponding file is displayed. I want to develop this further so that whatever file I drag onto the window, will be uploaded to my web server. For this, I need the application to log into my account on the host site, and send the file to the public-html folder in my web server. A progress bar to show upload progress would be good also, but for now, I'd appreciate some information on how to upload a file.
Any help is very much appreciated!
:)

'You personally', or anyone you should choose
to 'authorise'?Note the first is much simpler
than the second!

Hear, hear! Thin clients suck.

I'd have answered this sooner, except most
of the answer is not to a web start question!
What my advice breaks down to, is this.
Make an application that can upload files to a
site*, then wrap web start around it**.
This is because most of this can be done using
a standard application, that is the 'hard part',
and 'uploading a file' is better investigated on
more specific forums***.
* I am not very experienced with uploading files
programmatically, but it seems there might be a
number of ways -
- Call the Ant FTP task - kludgy, but relatively simple,
and should be easy if Ant is already installed.
- Use an FTP API
- Use HttpClient to mediate between the app. and server.
** Once you have a working application, it should
be relatively simple to deploy it using web start.
If the codebase is the same server as the upload
target, it might be possible to deploy the app. in
a sandbox (no code signing required), so long as you
convert the File operations to use the JNLP based
FileContents etc.
*** Sun does not seem to have forums very specific
to this task, but more on track are..
Core APIs - Networking
http://forum.java.sun.com/forum.jspa?forumID=536
This is a very generic networking forum, but there
might be some FTP gurus lurking.
These forums are more related to using Java on the
server side to accept the uploaded file, but if
the server already has FTP functionality, it would
be redundant..
Java Technologies for Web Services

Other Security APIs, Tools, and Issues
http://forum.java.sun.com/forum.jspa?forumID=60
If you have no luck on those, try posting to
one of the more generic usenet newsgroups, like
comp.lang.java.programmer - they should be able
to throw some ideas your way.
