Yes, contentLength is an INT. That is what was killing me when using
FileUpload 1.1.1. It would get a negative number as the content length
and throw that UnknownSizeException. The nightly builds seem to have
fixed that for me though as they actually pay attention to the maxSize
parameter now (i.e. if it is -1, then ignore contentSize).
As for the 32 bit windows/linux, i haven't tried that. I'm running on
64 bit linux/solaris.

By any chance, can it be limited by the contentLength of the http
request - because that's an INT?

Hi All
It's about the max allowable upload again.
Earlier, I was trying to upload a single file (from a servlet)
2GB, which didn't work. The methods I've been using are as
in the mail below.
It seems that the "handleFile" method isn't being invoked at all.
I tried to break the file into smaller chunks < 2GB, but even
in that case, the upload doesn't work, and now I'm getting an
error from the browser -
"The connection was reset
The connection to the server was reset while the page was loading.
* The site could be temporarily unavailable or too busy.
Try again
in a few
moments.
* If you are unable to load any pages, check your computer's
network
connection.
* If your computer or network is protected by a firewall
or proxy,
make sure
that Firefox is permitted to access the Web."
There is a similar error on IE too.
My question is - if there is a problem with the file size,
then the servlet should throw an exception while invoking the
commons upload APIs. But, it's not going there at all - as it
seems. I had a feeling that there might be limits in size in
the HTTP request itself - but even that's not the case because
I've been able to upload bigger files with the same code on a
Mac Powerbook (using commons-upload 1.0). It's failing when
I'm trying to do the same thing on a WinXP machine or a Linux
machine. Earlier I posted a message suspecting that it
probably has something to do with addressing system of the
machines - like 64 bit or 32 bits - but I thought that would
be the case for a single file size.
Has anyone been able to upload files > 2GB on a windows or linux (32
bit) system? Can you please give me some pointers?
Thanx in advance
Arijit

Hi All
I have been using the Apache Commons FileUpload package for some time
(mostly simple use cases) but stuck into something recently.
I'm trying
to upload files (greater than 2GB) onto a server using the commons
upload package within a servlet (inside tomcat). Anything
less than 2GB
works alright (although slowly), but anything more than that simply
doesn't do anything. In the "doPost" method of the servlet, I
have two
options based on an init parameter - either handling the option, or
handling the file - so the commons API's are used in the handleFile()
method -
public void doPost(HttpServletRequest request, HttpServletResponse
response)
throws IOException, ServletException {
try {
if (!init) {
mLog.debug("Handling file input...");
handleFile(request, response);
} else {
mLog.debug("Handling option input...");
handleRadioOption(request, response);
}
} catch (Exception ex) {
ex.printStackTrace();
}
}
private void handleFile(HttpServletRequest request,
HttpServletResponse
response)
throws IOException, ServletException {
PrintWriter out = response.getWriter();
...
boolean isMultipart =
ServletFileUpload.isMultipartContent(request);
// Create a new file upload handler
FileItemFactory factory = new DiskFileItemFactory();
ServletFileUpload upload = new ServletFileUpload(factory);
// Set overall request size constraint
upload.setSizeMax(-1);
upload.setFileSizeMax(-1);
// Parse the request
List items = upload.parseRequest(request);
...
}
It seems that when the files are selected and the "upload"
button is clicked on the browser (a submit action), the
control doesn't
go into this method at all - only when one of the files are
larger than
2GB - otherwise, it executes fine.
I've tried several combinations for setting the max file
size, but none
seem to work. Can it be related to the servlet APIs somehow? Is the
httpRequest size too large in this case?
Thanx in advance for any help.
Regards
Arijit
