I checked the code of tapestry-jquery and I think it should be fine
without setting the ordering. tapestry-jquery checks the same header to
determine if it's a request from its file upload comp. Since I already
changed that header, tapestry-jquery won't process and read the reqeust
inputstream.

I think that should work too but you have to ensure that your filter is before
the tapestry-jquery filter by using before:AjaxUploadFilter for ordering.

How would that work? will it disable both filters? One way I figured out is: I
changed the filter name and the AJAX_UPLOAD_HEADER in your code. I think it
should work. am I right?

One way to handle it would be to contribute an override for "AjaxUploadFilter"
to HttpServletRequestHandler with an empty implementation of HttpServletRequestFilter
Some thing like
public static void contributeHttpServletRequestHandler(final
OrderedConfiguration<HttpServletRequestFilter> configuration,
final AjaxUploadDecoder ajaxUploadDecoder) {
configuration.override("AjaxUploadFilter", new
EmptyHttpServletRequestImpl());
}

Hi Taha,
I used your comp first. Then other memeber in the team introduced
tapestry-jquery later. besides, I do more like the appearance of your comp than
he one in tapestry-jquery.

If you are already using tapestry-jquery why not use it's own Ajaxupload
component

Yes, thanks. I found that tapestry-jquery in my classpath and it intercept the
post request first sometimes. I'm wondering if there is any specific order the
request flows among several request filter chain contributed into Tapestry
HttpRequestHandler? From what I have seen, seems the order is random among
every application starts but it's fixed once the application is started. is
there any doc describe the order?

The stream can only be read once, so if you have another request filter
running before the AjaxFileUploadDecoder you'll need to make sure that it
did not read out the stream first.

I'm using Tapestry 5.3.3 and AjaxUpload comp blogged by Taha here:

Everything works fine but there is a strange problem. Sometimes the file
uploaded is alwasy empty(size 0). I checked
AjaxFileUploadDecoderImpl.**setupUploadedFile
and suspected the problem is in TapestryInternalUtils.copy. So I tried to
read the inputstream of the request myself. But strangely I always got
return value -1 when I call the inputream.read when the problem happens.
Looks the inputstream is totally empty. I checked the request sent by
browser with firebug and can see the content is sent by post. Don't know
why I just can not read it at server end.
One more interesting thing is that, this problem only happens sometimes
after tomcat6 is recycled. Fore example, I recycle tomcat 10 times and only
get problem with 1 time. With that recycle, all the file upload fails. The
problelm persists until I recycle tomcat again. With a good recycle, the
problem doesn't happen at all. I tested this on several machines with
different tomcat versions and see the same problem on all of them. I can
not get any clue and hope someone could give me some light. Thanks in
advance.
