Subject Re: [fileupload] Netscape/Firefox stream ended unexpectedly
Date Fri, 03 Sep 2004 14:48:05 GMT
Ok here is my next test.  Instead of doing the javascript submit, i've added a submit button
to the form and the data is upload just fine.  However this is not the desired process.  Sounds
like a Netscape/FireFox/Mozilla DOM issue.

So I'm still having problems uploading larger files. I have set the following up: 

static public final long SIZE_MAX = 40000000;
static public final int SIZE_THRESHHOLD = 65536;

DiskFileUpload upload = new DiskFileUpload();

List items = upload.parseRequest(request, SIZE_THRESHHOLD, SIZE_MAX, System.getProperty(""));

When the parseRequest begins it throws the exception that the stream ended unexpectedly. 

Has anyone tried this combination of submitting the form via JavaScript, with Netscape/Firefox/Mozilla?

Hope someone has had success with this combination and provide some guidance.

If the problem lies with large uploads, you may need to increase the
maximum request size that FileUpload will accept before bailing out.

get this issue of "Stream ended unexpectedly", as expected by adding an attachment. I've added
an "input" field submit button, then pressing the button to do the POST everything works.
However I can't use this behaviour, the submit must be executed via _javascript, without user
