Hi,
I have a panel with a FileUpload widget. It works fine in hosted mode,
Internet Explorer and Mozilla, but not in Chrome. In Chrome, it looks
slightly different, and the upload fails at the server end. In the
others, the upload works just fine.
In the other browsers (ie not Chrome), the panel shows a box, in which
the filename appears after I have selected it from the filesystem.
Next to that there is a button, labelled 'BROWSE'. Under that is the
submit button.
In Chrome, there is a label, which says 'Choose File' and next to
that, it says 'No file chosen'. So there isn't the usual box.
Underneath that is again the submit button. I can choose a file in
Chrome in the usual way (by pressing Choose File), but then if I
submit it, the upload fails on the server end, with the following
error:
org.apache.commons.fileupload.FileUploadException: Processing of
multipart/form-
data request failed. Connection reset
at org.apache.commons.fileupload.FileUploadBase.parseRequest
(FileUploadB
ase.java:384)

org.apache.commons.fileupload.servlet.ServletFileUpload.parseRequest(
ServletFileUpload.java:116)

icationFilterChain.java:290)

ilterChain.java:206)
My DoPost method in the upload servlet looks like this (as far as it
gets)
protected void doPost(HttpServletRequest request,
HttpServletResponse response) throws ServletException,
IOException
{
try {
ServletRequestContext ctx = new
ServletRequestContext(request);
if (ServletFileUpload.isMultipartContent(ctx) == false)
{
sendResponse(response, new FormResponse(
HttpServletResponse.SC_INTERNAL_SERVER_ERROR,
"The servlet can only handle
multipart requests."
+ " This is
probably a software bug."));
return;
}
// Create a new file upload handler
ServletFileUpload upload = new ServletFileUpload(
new DiskFileItemFactory());
// Parse the request
List<FileItem> items = upload.parseRequest(request);
And this final line throws the exception. (It's line 74)
I have posted this question on apache commons forum, but go no
response.
Why would this happen in Chrome, or how can I proceed to solve this
problem?
Thank you for your help,
Michel
