Title Body

I have a jsf view which shows some data from a managed-bean (viewscope) in a table, that is retrieved remotely. Currently the data is updated via polling from the client-view using primefaces poll component. This is not sufficient enough, since to much traffic is sent to client and now that primefaces supports server-push I only want to reload the data and push it to the client-view if data has been changed. This should be realized via polling from the web-tier to application tier calling a method like hasChanged(...) . If data is changed the web-tier pushes a notification to client to reload data. Current client poll client >> web-tier >> app-tier client asks web-tier via ajax for data which again asks app-tier for data and updates view Wished web-tier poll and push client << web-tier >> app-tier web-tier polls app-tier if data has changed and reloads on behalf and informs (pushes) client to update view Approaches: What is the best approach to realize the polling at the managed-bean in the web-tier? TimerTask in the managed-bean Spawning threads in a JSF managed bean for scheduled tasks using a timer Additional EJB with Schedule annotation Additional EJB with TimerService other? Edit: Architecture: (3-tier) Server1: database Server2: app-tier (EAR with Remote EJB + Hibernate) Server3: web-tier (WAR with JSF 2.0 + Primefaces 3.4) Client: Browser
