Hello. I have seen a few threads about Large file uploads on the
mailing list, but most people are saying Large means ~10MB. I'm trying
to upload files larger than 2 GB using FileUpload and HttpClient. I
know some people are going to say "why aren't you using ftp for that?"
but I have my reasons, so please try to help me with my problems with
FileUpload. It seems to work ok for files up to about 1GB, but once I'm
beyond that, it just hangs forever. Has anyone had luck doing this with
FileUpload? Also, the weird thing is that it seems like the whole file
gets there, but parseRequest never returns. And yes, I've let it sit
for hours...
This is basically what I have in my doPost method of my servlet:
public void doPost(HttpServletRequest request, HttpServletResponse
response) throws ServletException, IOException {
String tempStore = System.getProperty("java.iot.tmpdir");
int maxMemorySize = 10000;
ServletFileUpload sfu = new ServletFileUpload(new
DiskFileItemFactory(maxMemorySize, new File(tempStore)));
sfu.setSizeMax(-1);
List fileItems = sfu.parseRequest(request);
Iterator itr = fileItems.iterator();
while(itr.hasNext()) {
FileItem fi = (FileItem)itr.next();
if (!fi.isFormField()) {
File file = new File(tempStore + fi.getName());
fi.write(file);
}
}
}
Is there another why I should be doing this?
I have one other question too. Is there a way to parse the request with
out accepting the full multipart content? I'm using the HttpClient to
do this upload, and I'm setting a few StringParts in the request so that
I can authorize the user to upload. Doing it the way listed above, I
have to accept the entire request (i.e. they upload the whole file)
because I get those StringParts. Should I be putting those parameters
somewhere other than the PostMethod I'm sending in the executeMethod of
HttpClient?
Any help you all can give would be great! Thanks!
Andrew
