[appengine-java] Re: Dance Dance Robot error / Channel API
I cant make it work.. I am using appengine 1.3.5 and gwt 2.1.0 M2.
When I do "ant run" everything seems to go smoothly, but when I try to
use the application (filling the field "your name" ) I get the error
"Failure: This application is out of date, please click the refresh
button on your browser. (Expecting version 6 from server, got 5.)"
Any suggestion please?

Thanks Don. Including dev-channel-js.js works perfectly.

[appengine-java] Re: Dance Dance Robot error / Channel API
Wonderful! It seems multiple channels can be created with channel API. Wish we can try it on production server.

Re: [appengine-java] Re: Dance Dance Robot error / Channel API
Sorry, to be clear, I meant that you should create an /_ah/channel directory at the top of your war and copy dev-channel-js.js so it is a file named 'jsapi' in that /_ah/channel directory. This is the path that will work automatically in the 1.3.6 DevAppServer and in prod when this feature launches publicly. If you name the script something else (as you've done), that will work fine for now but you'll need to remember to adjust the path later.

Thanks, Don. It works like a charm after I include below line in html.

Re: [appengine-java] Re: Dance Dance Robot error / Channel API
Yes, this feature isn't launched in the production server yet. You can try it out in the 1.3.5 DevAppServer, but it requires a slightly workaround: 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 (as if it were a static file). Your HTML should then use

I have the same error using dev server. If you deploy your app to production server, below error log shows channel service is not enable. exception: com.google.apphosting.api.ApiProxy $FeatureNotEnabledException: The channel service is not enabled.

[appengine-java] Re: Dance Dance Robot error / Channel API
I did not get your error on running below code.
public static final native Channel createChannel(String channelId) /*-
{
return new $wnd.goog.appengine.Channel(channelId);
}-*/;
I have successfully create a channelId string on server side. The
format looks like "channel--9iwvs5-testing".
Then I use the channelId string in below code on the client side.
Channel channel = ChannelFactory.createChannel(channelId);
Unluckily below message is shown in the browser.
"Invalid token.Error 401"
Anyone has solve this token issue?

I believe you are using ,

Yes it is in App Engine 1.3.5. Look in the jar. I've got the backend
working already. There is no doc, just classes.
Among other things here is what there is:
import com.google.appengine.api.channel.ChannelMessage;
import com.google.appengine.api.channel.ChannelService;
import com.google.appengine.api.channel.ChannelServiceFactory;
and it all works.
