You are right about the jakarta commons fileupload and struts, you can't
use commons fileupload in an action, because struts have already taken
care of the multi-part parsing. You do have the option to make a servlet
and commons fileupload, where you will have total control of the form
data. I'm not certain about your way of making the files go into an
array. Is that the way to do it with for example html:text? One would
expect it to work in a similar fashion.

This link suggests that you use the same name all over again for each
entry, like "notworkingfile", "notworkingfile", and so on...

I would like to upload multiple files on a single web page by having
multiple <html:file> elements. The exact number of these are different
depending on the user who is using the application. So I want to store
this in an array (FormFile[]) in order to have N number of files
uploaded. When I try to use <html:file/> tags in an iterate loop (with
indexed="true") I get an error about requiring property attribute.
There's isn't a good way of doing that so I just rendered the the HTML
with scriplets. It looks something like:
<input type="file" name="workingfile"/>
<input type="file" name="notworkingfile[0]"/>
<input type="file" name="notworkingfile[1]"/>
<input type="file" name="notworkingfile[2]"/>
The form has getters and setters for workingfile (of type FormFile)
and notworkingfile ( of type FormFile[] that is 3 elements).
workingfile is assigned an instantied object however each element of
notworkingfile[] is null after submit.
I then attempted to use commons-fileupload-1.1.1 in a struts action
(struts 1.2.9) to read the uploaded data but it does not recognize
that any files are being uploaded (including workingfile). I tried
this code:
List items = new ServletFileUpload(
new DiskFileItemFactory()).parseRequest(request);
items results in an empty collection (but not null). I've read that
you can not use commons-fileupload in a struts action which may be why
that doesn't work. Anyone know how to have variable number of file
upload boxes? I know I could have properties for each file
(file1,file2,file3 and so on) instead of array but I'd rather not
implement it that way. Thanks!
