I create socket connection each time user logs into my application.
This means if they open new tabs within same browser window multiple
socket connections are established for each browser tabs. Problem
occurs when I close these tabs; inconsistently /disconnect inbound

Hi,
I'm not able to re-open a channel after the token expired.
I'm using GWT on the client side.
I am creating a new channel after the onError() method is called when the
token expires.
Everything looks ok but I do not get any events after reopening the channel.
I've read in another thread that I
I have had the Channel API working in development without any additional
configuration (using 1.5.1 Java).
When you say "not working", do you have any error message or exception
(either on client or server side)?

Channel API isn't working at all for me on development server - is there any
setting that isn't default? Everything works fine when I upload. I'm using
1.5.2 Java.

Hello, i have some simple questions regarding the channel api:
1. I know that after two hours, the given token for creating the
channel expires and onClose() and onError() are called. When this
happends, does the POST request to the path to disconnect servlet is
sent ? (/_ah/channel/disconnected/)
Hey,
I have created servlet which is hooked onto the POSTs for /_ah/channel/
connected/ and /_ah/channel/disconnected/. This is hit most of the
time, but it does not get executed every time.
Is this expected behaviour?
Thanks!

Hey,
I'm experimenting at the moment with the Channel API and I'm wondering
if the ChannelService.sendMessage() call is asynchronous. This is
because I am calling it within a servlet so if I need to call
ChannelService.sendMessage() on potentially 100 or so channels will
this be done asynchronousl
Hey folks.
I know that I'm not the first one who is facing this problem.
There is a similar thread, but I don't think it's exactly the same
problem.
I'm working on a project including GAE + GWT.
We are using gwt-gae-channel (http://code.google.com/p/gwt-gae-

Hi,
I have just started using Channel API and it look to work fine. But there
are few things i would like to know/clear/understand about my design.
My Design:
Currently when my site's page load it creates a token at server and injet
into HTML page, GWT then read the token and start listening to th
when using channel api, we need to keep track of all users so that we can
loop through the list and send broadcast message to all. how to know whether
user still connected without require user to frequently send ping back to
server that they are still opening browser?

You're trying to connect with the userId in your script. You need to
connect with the token. I made the same mistake the first time :)
BTW, here's a collaborative whiteboard demo with the channel API :

I have been trying to use the newly launched Channel API on SDK 1.4 in
my project. I try to push a message to client which actually pops up a
notification but I am getting the ChannelFailureException.
Here is the code:

The channel api as part of the 1.4 SDK release doesnt seem to work
when running locally, the onmessage callback never gets called. All
works fine when deployed though. Is there anything I need to do to

Hello there,
Google announced Channel API for 1.3.6 but it is still not live in
1.3.7. It runs in dev mode but when deployed I get a 'feature not
implemented' exception.
Does anyone has any updated on this? Google team?
Thank you.

The Channel API is not yet publicly launched. However, most of the
DevAppServer support was in 1.3.5.
Here's a workaround if you want to test it out:
Extract the "apphosting/tools/dev-channel-js.js" file from
appengine-api-1.0-sdk-1.3.5.jar and move it to /_ah/channel/jsapi in your
war directory
Hello there,
I am trying out the Channel API with my own project and the Google

when trying to push a message. There is no doc but all libraries are
available in the lastest GAE release. Here is the error:
