Agenda

Do Java EE 6 ao Java EE 7

Construindo aplicações HTML5– WebSockets 1.0

– JAX-RS 2.0

– JavaServer Faces 2.2

– JSON API 1.0

NetBeans e o suporte ao HTML5

Comunidade, Participação, Futuro


Plataforma Java EE 610 Dezembro, 2009


Java EE 6 – Estatísticas

● 50+ Milhões de Downloads de Componentes Java EE 6● #1 Escolha para Desenvolvedores Enterprise● #1 Plataforma de Desenvolvimento de Aplicações● Implementação mais Rápida de uma versão do Java EE


Top Ten Features no Java EE 6

1. Empacotar EJB dentro de um WAR2. Injeção de Dependência Type-safe3. Deployment descriptors opcionais (web.xml, faces-config.xml)

4. JSF padronizado com Facelets5. Uma única classe por EJB6. Extensões de Servlet e CDI7. CDI Events8. EJBContainer API9. Agendamento estilo Cron com @Schedule10. Web Profile


Java EE 7está pronto!


IntroducingJava EE 7 Live Webcast

http://bit.ly/javaee7launch


Java EE 7 Escopo

● Produtividade de Desenvolvimento– Menos código Boilerplate

– Funcionalidades mais ricas

– Mais convenções e defaults● Suporte a HTML5

– WebSocket

– JSON

– HTML5 Forms

JSR 342

Java EE 7 Web Profile

Web Profile updated to include– JAX-RS

– WebSocket

– JSON-P

– EJB 3.2 Lite

Outras APIs


Construindo aplicações HTML5

WebSocket 1.0 JAX-RS 2.0 JavaServer Faces 2.2 JSON-P API


HTTP vs WebSockets

Protocolo HTTP é half-duplex Gambiarras

– Polling

– Long polling

– Streaming

WebSocket resolve o problemade uma vez por todas

– Full-duplex


WebSockets Handshake

Cliente solicita um UPGRADE Server confirma (Servlet 3.1) Cliente recebe o OK Inicia a sessão WebSocket

http://farata.github.io/slidedecks/state_of_websocket/slides.html#13.4


Java API for WebSockets 1.0

API para definir WebSockets, tanto Client como Server– Annotation-driven (@ServerEndpoint)

– Interface-driven (Endpoint)

– Client (@ClientEndpoint)

SPI para data frames– Negociação handshake na abertura do WebSocket

Integração com o Java EE Web container



import javax.websocket.*;import javax.websocket.server.*;

@ServerEndpoint(“/hello”)public class HelloBean {

@OnMessage public String sayHello(String name) { return “Hello “ + name; }}

http://farata.github.io/slidedecks/state_of_websocket/slides.html#13.4



@ServerEndpoint(“/chat”)public class ChatBean {

@OnOpen public void onOpen(Session peer) { peers.add(peer); }

@OnClose public void onClose(Session peer) { peers.remove(peer); }

@OnMessage public void message(String msg, Session client) { peers.forEach(p > p.getRemote().sendMessage(msg)); }}


Maven Archetype para o Java EE 7

Maven Archetypes para Java EE 7– http://mojo.codehaus.org

Maven Archetype com o Embedded GlassFish configurado– http://github.com/glassfish/javaee7-archetype

Agora só precisa... – $ mvn package embedded-glassfish:run


JAX-RS 2.0

Client API Message Filters & Entity Interceptors Asynchronous Processing – Server & Client Suporte Hypermedia Common Configuration

– Compartilhar configuração comum entre diversos serviços REST


JAX-RS 2.0 - Client

// Get instance of ClientClient client = ClientFactory.getClient();

// Get customer name for the shipped productsString name = client.target(“http://.../orders/{orderId}/customer”) .resolveTemplate(“orderId”, “10”) .queryParam(“shipped”, “true)” .request() .get(String.class);


JAX-RS 2.0 - Server

@Path("/async/longRunning")public class MyResource {

@GET public void longRunningOp(@Suspended AsyncResponse ar) { ar.setTimeoutHandler(new MyTimoutHandler()); ar.setTimeout(15, SECONDS); Executors.newSingleThreadExecutor().submit(new Runnable() { public void run() { ... ar.resume(result); }}); }}


JavaServer Faces 2.2

Flow Faces HTML5 Friendly Markup Cross-site Request Forgery Protection Carregamento de Facelets via ResourceHandler Componente de File Upload Multi-templating


JSON API 1.0

JsonParser– Processa JSON em modo “streaming”

– Similar ao XMLStreamReader do StaX

Como criar– Json.createParser(...)

– Json.createParserFactory().createParser(...)

Eventos do processador– START_ARRAY, END_ARRAY, START_OBJECT, END_OBJECT, ...


JSON API 1.0

"phoneNumber": [ { "type": "home", "number": ”408-123-4567” }, { "type": ”work", "number": ”408-987-6543” }]

JsonGenerator jg = Json.createGenerator(...);jg. .beginArray("phoneNumber") .beginObject() .add("type", "home") .add("number", "408-123-4567") .endObject() .beginObject() .add("type", ”work") .add("number", "408-987-6543") .endObject() .endArray();jg.close();
