UltraCore Realtime engine

Posted by: Jesse in Untagged  on


The UltraCore realtime engine supports pushing realtime events to the browser. The technology behind the realtime implementation uses a dedicated connection between the browser and the server. The dedicated connection is used to stream realtime events directly to the client. The engine can work both in streaming and long polling mode (Comet style). The best possible protocol is automatically determined by the framework, depending on the browsers capabilities. Implementing realtime applications is as simple as implementing a realtime event handler, and generating realtime events that should be processed. The event listeners can push GUI updates to the browser, by just returning a modified GUI component. Example realtime event listener:

page.subscribeToTopic("topicName", new RealtimeListener() {

public Component liveEvent(Object eventData, Page currentPage) {
