maybe the problem is caused by
1. some plugin involved, like some kind of content rewriting.
2. process in the end method, maybe you missed checking it.

RE: [Catalyst] Pushing data to Catalyst powered web page
Hi all
I did the following to get data to push to the web page:
Scenario:
An RFID tag is read and processed by an ALE server. The ALE server then
sends the data to my Catalyst URL:
http://x.x.x.x:3000/ale/notifier?tagdata
The ale/notifier action then extracts the tag id from the variable and
then does a lookup in a database to get the data associated to the tag.
It then puts the tag data in a queue and the last action is to make a
socket connection, as a client, to a socket server running inside the
/assettracker/display_tagdata action. The following code is an extract
from the ale/notifier:
sub notify_tag_read {
use IO::Socket::INET;
my $MySocket=new
IO::Socket::INET->new(PeerPort=>26482,Proto=>'udp',PeerAddr=>'x.x.x.x');
my $msg = "";
$MySocket->send($msg);
}
When I access, via a browser, the url
http://x.x.x.x:3000/assettracker/display_tagdata
it loads a socket server and waits for a connection from a client. The
following is a snippet of the /assettracker/display_tagdata action:
sub display_tagdata : Local {
my ( $self, $c ) = @_;
my $text;
my @args;
$c->stash->{template} = 'sockettest.tt2';
use IO::Socket::INET;
my $MySocket=new
IO::Socket::INET->new(LocalPort=>26482,Proto=>'udp',Reuse=>1);
$MySocket->recv($text,128);
@args = [$text];
$c->forward('get_tagdata',[EMAIL PROTECTED]);
}
This action will then forward to /assettracker/get_data to retrieve the
data from the queue and display it in the browser.
I know that the code is not great, but it works. Thank you for all the
assistance that I received.
Regards
Morne

Pull with an AJAX update, perhaps.

RE: [Catalyst] Pushing data to Catalyst powered web page
Morning to everybody that has assisted so far.
I have not been able to resolve the problem yet, most likely because I
did not explain my issue correctly.
I think that I require some kind of publish and subscribe solution for
this. I really want to use Catalyst as far as possible, as it has really
been useful in other projects.
I need my "view tag data" page to subscribe to a publisher. When the
publisher receives new tag data it should push it to the subscriber so
the subscriber can then show it on its page automagically.
Regards
Morne

If you want an upload of your data (i.e., tagdata.txt) to a web page,
then I
think its nothing to do with catalyst. Use the LWP module where you can
POST
file to a web page. This link might help->

[Catalyst] Pushing data to Catalyst powered web page
Good afternoon all
I am busy with a project where I need to read an RFID tag, get the data
associated with the tag and then push the data to a web page for a
security person to monitor.
I can successfully read the tag by using LogicAlloy's ALE server. It
then calls my Catalyst application at http://localhost/ale/notifier :
sub notifier : Private {
my ( $self, $c ) = @_;
#$c->stash->{template} = 'notifier.tt2';
$c->stash->{tagdata} = $c->request->params->{tagdata};
open (TagData, '>C:\Eclipse Projects\Asset
Tracker\AssetTracker\lib\AssetTracker\tagdata.txt');
print TagData $c->request->params->{tagdata};
close TagData;
}
As you can see I do not get the associated tag data yet, I am just
trying to display the tag data received from the ALE server.
I can see that the data is coming through correctly by monitoring the
console debug and checking the tagdata.txt file.
The problem that I have is that I have no idea how to push the data to a
web page instead of pulling.
I have tried using catalyst redirect, forward and subrequest with no
luck.
I am not a hard core developer, so any assistance will be greatly
appreciated.

Morne Supra
