Juggarnaut installation on windows


I am trying to create chat application on windows. For this I am using Juggarnaut. For using juggarnaut, we need to start push_server. But I am not getting how to run push_server on windows.

From one of the tutorial I ran this command for starting push_server,

ruby script/push_server from my project folder.

But I got Load error for push_server.

I am using ruby - 1.8.6 rails - 2.0.2

juggarnaut - 0.5.1 json - 1.1.1 eventmachine - 0.12.0

Can anyone tell me how to use juggarnaut on windows?

Or are there any other options to create chat application on windows with rails? instead of coding it?

Thanks, Shalmali
