This Java classes can be used to communicate very easily with the Pusher REST API (http://www.pusherapp.com) from any Google App engine Web application.

Simply replace the Pusher specific constants in Pusher.java:

private final static String pusherApplicationId = ""; private final static String pusherApplicationKey = ""; private final static String pusherApplicationSecret = ""; 

Call one of the two available static methods called "triggerPush" and pass channel name, event name and the message body (JSON encoded data) as parameters:

Pusher.triggerPush("test_channel", "my_event", jsonData); 

The second "triggerPush" method provides an additional parameter for the socket_id:

Pusher.triggerPush("test_channel", "my_event", jsonData, socketId); 

That's it.

Sometimes it can be very convenient to prepulate a PusherRequest instance with default channel and/or event name:

PusherRequest p = new PusherRequest("test_channel","my_event"); 

To send a request to the Pusher API just call "triggerPush" on this instance:

p.triggerPush(jsondata);
