I have a usecase for which I would like to know if HTML5's Server-sent-Events is suitable. Multiple clients (Javascript+HTML5 browsers) connect to the web server (with a Java EE backend). Each client could be looking at a different view at any time, depending on what is their object of interest. My Question is: How to keep multiple clients (on different views) up-to-date on the updates happening on the server-side, without flooding all clients with all updates on all views ? Important points that I need to consider are: Many clients might be interested in the same events. If two clients are

I've seen a number of Atmosphere examples including pub-sub. I want to do something like pub-sub (client subscribes to a channel that is unique to that client; server periodically publishes to that channel), except that the client will send data to the server as well. The client will send data in response to data sent by the server and in other cases when something important happens on the client that the server needs to know about (which the server doesn't need to acknowledge). Is it even possible to do this with Atmosphere? It might look something like this: @Stateless @Path("/id/{clientId}

I'm sending huge chunks of JSON data through websockets. The JSON may have over 1000 entries. Due to the frame size limitation, the Websocket protocol automatically splits the JSON into frames, which cannot be helped. As we cannot change the frame size of websockets. The problem: When I try to evaluate my JSON using JSON.parse it gives me a parsing error which is obvious because the frames are not complete JSON objects. All this happens in the Websocket onmessage event callback. How can I recieve the huge JSON in differnt frames and still be able to parse it? I have tried to concat the frames
