Atmosphere on JRuby

Atmosphere on JRuby

Reply Threaded

Hi all. I'm trying out the JRuby demo (http://weblogs.java.net/blog/jfarcand/archive/2009/09/10/writing-comet-applications-using-jruby-and-atmosphere-framework and http://gist.github.com/221856). The source code provided on the atmosphere site is missing the index.html file -- anyone know where I can find that?

Anyway, regardless, I tried to boot it up and go this error:

[~/lib/jetty/webapps] jruby chat.rb

I'm using JRuby 1.3.1. Anyone know what the issue is?

Thanks!

Woops... what I meant to say was that the chat.html is missing and I had to modify the code with this http://gist.github.com/221900.

Anyone know where I can find the contents of chat.html?

Oh my bad. The sample was using Atmosphere 0.3.1 API

I'm attaching the sample tested with:

jruby 1.3.1 (ruby 1.8.6p287) (2009-06-15 6586) (Java HotSpot(TM) Server
VM 1.6.0_13) [i386-java]

Apology that! Forgot to update that sample.

Cool.thx. I noticed that the demo uses http streaming through an iframe. Is it possible to use long-polling with JRuby?

Yes, just use normal Javascript intead of an iFrame, or stick with an
iFrame and just add the following line inside the onStateChange method:

> def onStateChange(resourceEvent)
> writer = resourceEvent.getResource().getResponse().getWriter()
> writer.write(resourceEvent.getMessage().to_s.ljust(1*1024))

The line is:

resourceEvent.getResource().resume();

which will resume the response, hence long-polling.
