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

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

Web Tier

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

21

Web Socket Sample (w/Grizzly WebSocket API)

public class ChatApplication extends WebSocketApplication<ChatWebSocket> { protected ChatWebSocket createWebSocket(Connection c, ServerWebSocketMeta m) { return new ChatWebSocket(c, m, this); }

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”); }}

22

Async Web Sample (w/Atmosphere)

@Path("/{topic}")@Produces("text/plain;charset=ISO-8859-1")public class PubSub { private @PathParam("topic") Broadcaster topic;

@GET @Suspend public Broadcastable subscribe() { return new Broadcastable("",topic); }

@POST @Broadcast @Consumes(MediaType.APPLICATION_FORM_URLENCODED) public Broadcastable publish( @FormParam("message") String message) { return new Broadcastable(message,topic); }}

23

JAX-RS 2.0 Client API (w/Jersey)

WebResource r = Client.create().resource("http://example.com");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());

http://example.com/

24
