WebSocketBehavior has only callbacks. They have IPartialPageUpdateHandler as parameter (this is the base interface for AjaxRequestTarget and IWebSocketRequestHandler) which you can use to add components.
There are two use cases: 1) the browser sends a message WebSocketBehavior#onMessage(Text|Binary, IPartialPageUpdateHandler) is called and you can react on this message 2) the server pushes a message 2.1) simple case: broadcast plain text or byte[] WebSocketSettings webSocketSettings = WebSocketSettings.Holder.get( application); webSocketSettings.getConnectionRegistry().getConnection(app[, sessionId, pageIdKey]).sendMessage( text | binary ); 2.2) more complex case: update Wicket components here you need to broadcast IWebSocketPushMessage - this is a specialization of IWebSocketMessage that is used when you need to push from the server to the client This code could be in any application service class: WebSocketSettings webSocketSettings = WebSocketSettings.Holder.get( application); WebSocketPushBroadcaster broadcaster = new WebSocketPushBroadcaster( webSocketSettings.getConnectionRegistry()); 2.2.1) to all connections: broadcaster.broadcastAll(application, message); 2.2.2) to specific client ConnectedMessage wsMessage = new ConnectedMessage(application, sessionId, pageIdKey); broadcaster.broadcast(wsMessage, message); Broadcasting IWebSocketPushMessage will call WebSocketBehavior#onPush() where you can update any components We should add this to the guide!
