Atmosphere talks @ Javaone 2010 on Websocket, Comet and JQuery

1. Building Powerful WebSocket, Comet, and RESTful Applications Using Atmosphere http://twitter.com/atmo_framework Jeanfrancois Arcand http://twitter.com/jfarcand Paul Sandoz http://twitter.com/PaulSandoz

2. Creator of the Grizzly Framework Creatpr of GlassFish v3 Grizzly Micro Kernel Creator and Co-Leader of Atmosphere Jeanfrancois 9 years @ Sun Microsystem Creator Async Http Client Co-leader of Atmosphere Creator and Lead of Jersey Paul 13 years @ Sun Microsystem Java Champion

3. News and Update Comet and WebSocket Protocol The Atmosphere Framework Ya Ya Ya That’s Impossible High-level RESTful and asynchronous applications Twitter Search Conclusion Q & A

18. Why

19. Clustering Why

20. JMS JGroups Clustering Why

21. JMS JGroups Clustering Guarantee Delivery Why

22. Cache JMS JGroups OOM Manager Clustering Guarantee Delivery Events Aggregation Proxy Why

23. Cache JMS JGroups OOM Manager Clustering Guarantee Delivery Events Aggregation Proxy Why Portable & Unified

24. Cache JMS JGroups OOM Manager Clustering Guarantee Delivery Events Aggregation Proxy Why Servlet 3.0 Blocking I/O Portable & Unified Comet Native Web Socket New protocol

25. Cache JMS JGroups OOM Manager Clustering Guarantee Delivery Events Aggregation Proxy Why Servlet 3.0 Blocking I/O Portable & Unified Client Comet Native Web Socket New protocol

26. Cache JMS JGroups OOM Manager Clustering Guarantee Delivery Events Aggregation Proxy Why Servlet 3.0 Blocking I/O GWT JQuery Portable & Unified Client Java EE Comet Native Web Socket Grails JSF New protocol

27. Cache JMS JGroups OOM Manager Clustering Guarantee Delivery Events Aggregation Proxy Why JRuby Servlet 3.0 Blocking I/O GWT JQuery Portable & Unified Client Java EE Comet Native Web Socket Grails JSF New protocol

28. Cache JMS JGroups OOM Manager Clustering Guarantee Delivery Events Aggregation Proxy Why JRuby Groovy Servlet 3.0 Blocking I/O GWT JQuery Portable & Unified Client Java EE Comet Native Web Socket Grails JSF New protocol

29. Cache JMS JGroups OOM Manager Clustering Guarantee Delivery Events Aggregation Proxy Why JRuby Scala Groovy Servlet 3.0 Blocking I/O GWT JQuery Portable & Unified Client Java EE Comet Native Web Socket Grails JSF New protocol

30. Same API everywhere. No need to learn the protocol!

31. Comet Web Socket IE Chrome JQuery Plugin Auto detect best transport to use! Emulate WebSocket! Comet Web Socket Web Socket Server Side Events Safari Firefox Opera Comet Comet Comet

32. Ya Ya Ya That’s impossible!

33. @Path("/pubsub/{topic}") @Produces("text/html;charset=ISO-8859-1") public class JQueryPubSub { private @PathParam("topic") Broadcaster topic; @GET public SuspendResponse<String> subscribe() { return new SuspendResponse.SuspendResponseBuilder<String>() .broadcaster(topic) .outputComments(true) .addListener(new EventsLogger()) .build(); } @POST @Broadcast public Broadcastable publish(@FormParam("message") String message) { return new Broadcastable(message, "", topic); }

34. function subscribe() { function callback(response) { if (response.transport != 'polling' && response.state != 'connected' && response.state != 'closed') { if (response.status == 200) { var data = response.responseBody if (data.length > 0) { $('ul').prepend($('<li></li>').text(" Message Received: " + data + " using transport: " + response.transport)); } } } } $.atmosphere.subscribe(document.location.toString() + 'pubsub/' + getElementByIdValue('topic'), callback : callback, $.atmosphere.request = {transport: getElementByIdValue('transport')}); }

36. Jersey is the reference implementation and provides additional functionality

37. Atmosphere leverages the extensibility of Jersey

38. Atmosphere and Jersey can evolve at their own rates

40. Suspend a response

41. @Resume

42. Resume a response

43. @Broadcast or Broadcaster API

44. Broadcast events

45. @Schedule

46. Schedule execution of periodic broadcast

47. @Cluster

49. Conclusion Write Powerfull Asynchronous Web Application using Atmosphere Write once, Run Anywhere Transport free! Browser nightmare free Extremely Simple! Join the community http://github.com/Atmosphere/atmosphere
