I'm not sure you understood my question correctly, because I have no idea what
your answer is supposed to be.
Lets try this again.
I have an web app that uses Apache Commons FileUpload to upload files. I am
using the streaming api to stream files up, and then save them to my server.
This has nothing to do with my war file, or application files, this has to do
with user submitted files that they themselves will be using on.
I haven't exactly done the saving, but I know I can save it to my own
filesystem, so I don't think there should be much of a problem saving it to my
server.
What I am asking is this.
The FileUpload uses a multipart form which is how the data is sent.
<form method="POST" enctype="multipart/form-data" action="fup.cgi">
File to upload: <input type="file" name="upfile"><br/>
Notes about the file: <input type="text" name="note"><br/>
<br/>
<input type="submit" value="Press"> to upload the file!
</form>
With this I will select multiple files for upload.
The issue is, I am upload a file, that contains additional data for files to be
uploaded. Lets call this file A. File A has to be read in order to upload
additional files which are images.
So when we look at this.
// Check that we have a file upload request
boolean isMultipart = ServletFileUpload.isMultipartContent(request);// Create a
new file upload handler
ServletFileUpload upload = new ServletFileUpload();
// Parse the request
FileItemIterator iter = upload.getItemIterator(request);
while (iter.hasNext()) {
FileItemStream item = iter.next();
String name = item.getFieldName();
InputStream stream = item.openStream();
We see that the data for the file to be uploaded was sent over through a
request.
My question is basically I want to be able to add additional data to that
request, but I am not adding it myself. Once I submit a file through the form,
I want to be able to submit more data, and how I do that is my question. I
want to know what exactly is FileUpload doing to grab the images and parse them
into the Input Stream? What exactly is the multipart/data form doing to make
this happened, that is what I'm really looking for. I will go look over the
SRC, but I figured I would ask here.
As I mentioned before I have a few options that I thought of.
1. Red the data mid stream, and then upload the file(how do I upload)?
2. Save the file then upload.
A. Use a Servlet to fake a form and pass the data to itself?
So again, user selects file, I read file, then select other files from their
system that are needed for the first file, and upload them all up at the same
time.
Thanks!
