3 Java EE for the Cloud Tighter requirements for resource and state management Better isolation between applications Potential standard APIs for NRDBMS, caching, other Common management and monitoring interfaces Evolution, not revolution 3

4 Better Packaging for the Cloud Apps are versioned Multiple versions can coexist Must deal with data versioning, upgrades, etc. Need ability to specify QoS properties Apps both expose and connect to services 4

20 Web Tier Web socket support Standard JSON API HTML5 support NIO.2-based web container 20

21 Web Socket Sample (w/grizzly WebSocket API) public class ChatApplication extends WebSocketApplication<ChatWebSocket> { protected ChatWebSocket createwebsocket(connection c, { return new ChatWebSocket(c, m, this); } ServerWebSocketMeta m) public void onmessage(chatwebsocket s, DataFrame frame) { String msg = frame.getastext(); s.sendjson(s.getuser(), msg); } } public void onclose(chatwebsocket s) { s.sendjson( system, s.getuser() + left the chat ); } 21

22 Async Web public class PubSub { public Broadcastable subscribe() { return new @Consumes(MediaType.APPLICATION_FORM_URLENCODED) public Broadcastable String message) { return new Broadcastable(message,topic); } } 22

23 JAX-RS 2.0 Client API (w/jersey) WebResource r = Client.create().resource(" WebResource content = r.path("containers").path("quotes"); content.path("1").type(mediatype.text_plain).put("something is rotten in the state of Denmark"); ClientResponse response = content.path("1").header("if-modified-since", lastmodified).header("if-none-match", etag).get(clientresponse.class); assertequals(response.status.not_modified, response.getresponsestatus()); 23

24 JSF 2.2 HTML5 support Semantic tags, browser feature detection Use of HTML5 by components Audio and video JSR-276 (tool support) Mobile renderkits Page resolver and application context manager API Performance 24

25 JMS 2.0 Much needed update! Ease of development makeover Better integration with application servers Standardize some common vendor extensions 25

26 JPA 2.1 Candidate Features Converters / custom types Fetch plans / profiles Additional mapping metadata User-defined naming strategies More flexibility in use of generated values Immutable attributes; readonly entities More flexible XML descriptors Additional event listeners and callbacks Support for stored procedures Additional built-in functions Database and vendor function invocation support Downcasting Outer joins with ON conditions Update and delete criteria queries Mapping between JPQL and criteria queries Improved result type mapping for native queries Improved control of persistence context synchronization Support for dynamic definition of persistence unit Extension of Metamodel API to ORM Methods for dirty detection Additional unwrap methods 26
