Mark, I tried the patch(gears.jar from issue 201) for multiple file upload. I 
am able
to select multiple files both in hosted and non hosted mode. However when I 
press
open, I get a exception in hosted mode(as a stacktrace in eclipse). Works in
browser(compile/browse). Here is the error: 

java.lang.ClassCastException

Re: Comment #1

Hmm. As far as I know, none of this will work in hosted mode because
it requires Gears being installed.

Now I have some seen some interesting things happen where plugins
appear to be installed in Hosted mode. Specifically, flash...  and it
loads, but cannot properly handle javascript interaction
(ExternalInterface, etc).

Can any GWT devs shed some light on this?  Does the GWT shell use
${HOME}/.mozilla for it's profile?

Anyway the thing to remember is, always check to make sure gears is
installed first. Though, in your case it seems like it might have
returned true anyhow... ?

Are you on windows?

the
GWT 1.5 release"

While you folks are working on the desktop integration, is it possible to make 
the
File Blob request send over to server as Multi-Part? Probably this should be 
taken
care by the Gears team but if it is something that can be taken by the 
gwt-google-api
team that will be great. Frankly I am not sure how this can be done otherwise I 
would
have contributed. 

When a file is selected by the browser, it injects periodic markers called as
multipart boundary. These markers are used by utilities like the apache file 
upload
on the server to reconstruct the file(probably in pieces, not exactly sure how 
it
works). Multipart boundary is totally missing in the Blob that we upload.

While I think this issue might be better discussed on the Gears group, I wanted 
to
mention I put together a gwt-gears sample project for upload, including a 
servlet
which receives files. 

Before I send along the sample I have some questions about project layout, 
because
I'm having trouble launching the app from the project itself (works fine in the
original project, but that uses maven).

Let's treat the sample as a separate change.  I can easily craft it into the 
same
format as the rest of the samples.  To launch it in place, we usually use the 
eclipse
project.  Once the project is build into a distribution, it creates launch 
scripts in
the distribution.

It seems to work, now that you pointed how how the launch scripts should be 
used. I
works once built into the distribution. The upload sample displays a form 
similar to
a standard <form> with <input type="file"> but uses Gears and has a progress 
display bar.

It needs a servlet to receive the file so it only works when launched from the 
shell
in web mode (or possibly packaged as a .war and deployed to a server).

Where should I post it, and in what form?
