17 May 2016 Starting with JSF 2.3-m05 we can take advantage of a brand new feature - register a WebSocket push connection in client side.

JSF WebSocket support In typical web applications, servers always respond to requests from a browser; there is no way for a server to send data to the client browser without responding to a request. WebSocket technology provides full duplex communication between a browser and a server, allowing servers to independently send data to a client, without having to respond to a request.

To enable websocket support, you have to add javax.faces.ENABLE_WEBSOCKET_ENDPOINT in web.xml. WebSocket libraries are available in different languages so we have many options for testing our server endpoints. Since we don’t want to download any extra library we will use the JavaScript WebSocket … websocket (JSF 2.3 View Declaration Language: Facelets Variant, generated with VDLDoc.) Description: Registers a websocket push connection in client side by rendering the necessary scripts. Push messages can be sent from server side via javax.faces.push.PushContext interface.

Plain WebSocket can be up to 3.7 times as fast to receive a message from the server compared to Socket.IO and 1.7 times as fast compared to SockJS. Plain WebSocket scales well in terms of response time and memory requirement with higher concurrency levels. Socket.IO requires a lot of memory which is a potential problem.

webSocket is a factory function that produces a WebSocketSubject, which can be used to make WebSocket connection with an arbitrary endpoint. webSocket accepts as an argument either a string with url of WebSocket endpoint, or an WebSocketSubjectConfig object for providing additional configuration, as well as Observers for tracking lifecycle of WebSocket connection.

Starting with JSF 2.3-m05 we can take advantage of a brand new feature - register a WebSocket push connection in client side. Thanks to the JSF team (especially to Bauke Scholtz (aka BalusC)) this feature is available in today milestone via tag. It is interpreted as a JavaScript instruction to open or close the WebSocket push connection. This attribute is implicitly re-evaluated on every ajax request by a PreRenderViewEvent listener on the UIViewRoot. You can also explicitly set it to false and then manually control it in JavaScript using jsf.push.open(clientId) and jsf.push.close(clientId). While the WebSocket specification is part … of the Java EE spec as a whole, … some vendors have implementation-specific quirks … that might require some extra configuration. … WildFly, aka Jboss, runs the TRACE implementation.
