But... If you took the form approach like I've shown, there's nothing to stop you from dynamically adding elements to the form as more files are selected. However, they user would have to select a file, click Add (or something like that), then do that again until they were done. If *that* would fulfill the requirements of the OP, I think that could be done.

for sure there is no doubt on my side ;-) this is exactly what i meant if you keep the number of files "constant". but as the originator of this thread alreay said: he looks for a solution of multiple file SELECTION. beside the applet i have no idea how to solve that....

Betreff: Re: AW: AW: Multi-select file chooser
Just in case there was any doubt, here's the form from my web hosts' file manager I was referring to:
<form action="doupload.html" method=POST ENCTYPE="multipart/form-data" target=infofr>
<input type="file" name="file1">
<input type="file" name="file2">
<input type="file" name="file3">
<input type="file" name="file4">
<input type="file" name="file5">
<input type="file" name="file6">
<input type="file" name="file7">
<input type="file" name="file8">
<input type="file" name="file9">
<input type="file" name="file10">
<input type="file" name="file11">
<input type="file" name="file12">
<br>
Overwrite existing files:
<input type="checkbox" name="overwrite" value="1">
<br>
<input type="submit" value="Upload">
</form>
I could think of some better ways to do present the UI, but that's the basic idea. Heck, throw that in a .tag file and your all set (in a basic way).

another solution would be to use (signed) java applets, which is (for the enduser) the best looking solution, but the effort to do so is REALLY BIG, so if you don't get paid like mad forget it....

You can have as many <file> elements in a form as you want, and you can process them all at once. My web host (LunarPages) has a decent file manager, one of the functions it has is the ability to upload up to 12
files
at a time.
I don't know of any single tag to render such a form, but that's really
what
you need, and it should be trivial to write (although I'd bet it exists somewhere). It's the server-side processing that *could* be tricky (although I think Commons Upload would deal with it just fine, probably
give
you a collection or something, I forget what the interface looks like.)

this is standard browser behaviour, haven't seen any browser who would allow you to select more than one file.
reason for that is that your form only includes one form field of type file, so how can the browser add more than one file in a way that your app understands this?
the only chance for multiple file selection is to ask the user before generation of the form "how many files do you want to upload", or by adding another file field to the form as soon as the user selects one (using javascript; but this is quite ugly and can make a lot of troubles with different browser or javascript-disabled ones...) or he/she upload a zip file...
if there is someone outside who knows a better solution, let us know, this is a very common problem.

Wow, what browser is that? Can they hold down CTRL? (assuming Windows)

Hi, I'm using the "file" tag to select a file from my jsp. The default browser allows the user to select only 1 file at a time. The user can not multi select files or a directory.
Does anyone know of a multi-select file and directory chooser?
Thanks very much.
