Hi Friends,
I have few questions about the commons file upload.
1) Is commons file upload suitable for uploading
files>10MB in size?
What we have observed that commons file upload load a
file in memory. So for files > 10MB the deply in
response is too much.
Is this right? Is there something we are missing?
Is there any other good variation of commons file
upload if we have to use it for uploads upto 30MB?
2)When we try uploading a file>40MB, we are getting
Items list as 0.
So there is nothing to iterate on and check if it is a
file.
Code is like the following:
// Create a new file upload handler
ServletFileUpload upload = new
ServletFileUpload(factory);
// Parse the request
List /* FileItem */ items =
upload.parseRequest(request);
// Process the uploaded items
Iterator iter = items.iterator();
while (iter.hasNext()) {
FileItem item = (FileItem) iter.next();
if (item.isFormField()) {
processFormField(item);
} else {
processUploadedFile(item);
}
}
We trapped this scenario and added code to show some
customized error when Items are 0. But then it takes
agaes to display the error message on screen when from
the logs we can make out that the control did go till
the point of displaying the error message to screen.
Do not know why this behaviour for large files
[>40MB]. It can be good to know the some threshold at
which such error occurs and if it is a known problem
with commons fileupload.
Regards,
