Atmosphere - how to push data from struts 2 action

Question

my question is how to push data from server in atmosphere without using javaScript

I followed the chat tutorial it was so understandable, now I want to push data from an action in struts 2 (and not from javascript) i know that I must call .onMessage() method but I'm blocked on how to build AtmosphereResponse argument I tried

AtmosphereResponse response = new AtmosphereResponse.Builder().build();

but it return NullPointerExeption when I use response.write() methode

Solution : BroadcasterFactory.getDefault().lookup("/atmosphere").broadcast(message);
