WebResponse ContentLength > 2G
I'm trying to send a file >2G using ResourceStreamRequestTarget +
FileResourceStream, but the content-type is always set to a big negative
value typical of a long(>2G) to int conversion.
This is non-standard and the proxy we use refuses it (most browser just
ignore it, but the RFC states that the value must be >0).
After looking deeper in the code I see that, in wicket, longs are used
for the content length across the board, but when this is transfered to
a HttpServletResponse there is an (int) cast.
Shouldn't wicket use ints to remove the confusion, or if not (and I
think this is the best course), shouldn't a test be made
if > Integer.MAX_VALUE
httpServletResponse.addHeader("Content-Length", Long.toString(length));
instead
?
I tried the last approach overriding newWebResponse on WebApplication
with my custom WebResponse and it fixed my problem.
Should I open a bug?
Thanks

Hi,
this is probably a bug in wicket where the queue is not resumed after
redirect. Normally this is not needed, but since your redirect is an
attachement the page stays active. Can you please open a jira issue for
this? It shouldn't be difficult to fix.

the problem is since I'm not actually redirected to a page (I get a file

anymore.
If I click on them I get 'Channel busy - postponing'.
I'm using wicket 1.3.4.
The redirect seems to happen, but only once.
Say there are 3 files to download on the page, I would need to:
click link1 -> download the file -> refresh the page -> click link2 -. etc.
I shouldn't need to refresh the page.
If I don't refresh the page, when I click link2 I'll get 'Channel busy -
postponing'.
BTW:
On the first link click in firebug I get this in the response headers:
Ajax-Location ../../../../fileDownload?type=RUN_REGION_READS_FILE&id=246
which makes sens since the QueryStringUrlCodingStrategy is mounted on
'fileDownload'.

So here's the path that causes the error:
onClick->setResponsePage->decode->ResourceStreamRequestTarget
Once a link has been clicked no other links are clickable on the page.

Re: Popup from a link
You can check out the example in wicket extensions: http://www.wicket-library.com/wicket-examples/ajax/modal-window.0;jsessionid=D48A81DCC881B0D8A11DAA7EE39C81B1 http://www.wicketframework.org/wicket-extensions/apidocs/wicket/extensions/ajax/markup/html/modal/ModalWindow.html If you want to reuse the modal popup elsewere, there is an example on how to do this nicely here: http://stuq.nl/weblog/2008-06-05/wicket-how-to-write-a-reusable-modal-window-popup hope it helps.

How to stream a file instead of rendering a page?
I need to stream a file to the browser, simple enough...but the file might be staged (on tape on a SAN). In which case I want to display page telling the user to come back, the file will be ready in X time. What I did was mount a QueryStringUrlCodingStrategy in which I overrided decode. If the file is available I return a ResourceStreamRequestTarget if it is not I let QueryStringUrlCodingStrategy.decode call the notification Page. I works, but I was curious to know if there is a way to do this from within the page without the mount? If I put RequestCycle.get().setRequestTarget() in the constructor, it won't work once the page is in the user's session. I can't put it in respond() because it's too late in the processing (or is it?). Any ideas, or the way I did it is the only way. (I'm still getting my bearings around wicket and I'm trying to find the best practices). Thanks - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
