Java EE 8 Themes

• HTML5 / Web Tier Enhancements •  Ease of Development / CDI alignment •  Infrastructure for running in the Cloud

• Driven by Community Feedback

4

JSR 366


Community PrioriJzed Features

5


CDI 2.0

•  Events – Asynchronous events – Event ordering – Event Range (war, ear, server, cluster)

•  Interceptor / Decorator (AOP) – Support AOP on custom or produced bean – Support AOP on inner calls (AOP enable when a method is called in same class)

6

JSR 365

•  SPI enhancement – Be\er access to CDI meta data – Contexts enhancement for 3rd party Spec


CDI 2.0 (cont.)

• Parts (“sub-‐spec with sub-‐impl.”) – CDI Light (simple IoC soluJon) – Event

•  Java SE support – Boot CDI from Java SE – Add SPI to easily integrate CDI in custom stack (i.e plug transacJon manager)

7

JSR 365


JSON-‐B 1.0

• ConverJng Java objects to & from JSON •  Supports for different providers – Leverages mature JSON Binding frameworks – With a standard API

• Mapping – Default + customized

8

JSR 367


JMS 2.1

• New API to receive messages asynchronously – In Java SE, remove need to implement MessageListener – In Java EE, a simpler and more flexible alternaJve to JMS MDBs •  Simpler, JMS-‐specific annotaJons that allow any managed bean to listen for JMS messages •  No need to implement MessageListener •  No need to be restricted to MDB lifecycle

9

JSR 368

@RequestScoped public class MyListenerComponent { @JMSListener(destinationLookup="myQueue") @Transactional public void myCallback(Message message) { ... ... } }


JMS 2.1 (cont.)

• Completes ease-‐of-‐use improvements started in JMS 2.0 •  Improved portability of JMS providers between ApplicaJon Servers •  Further clarify behavior of JMS in a Java EE applicaJons • CorrecJons and improvements to new JMS 2.0 features •  Extend specificaJon to cover redelivery loops and dead message queues • Other features proposed by the community and the Experts Group

10

JSR 368


Servlet 4.0

• Request/response mulJplexing – Servlet Request as HTTP/2 message

•  Stream prioriJzaJon – Add stream priority to H\pServletRequest

•  Server push • Binary framing – Hidden from API

• Upgrade from HTTP 1.1

11

JSR 369


Servlet 4.0

•  Servlet 4.0 is important because HTTP 2.0 is important • HTTP 2.0 compliance – Server Push – Stream Priority – Upgrade from HTTP 1.1

• Compliance with latest HTTP 1.1 RFCs 7230 – 7235 – IETF PRECIS framework for secure Unicode – Numerous small compliance issues

12

JSR 369


JAX-‐RS 2.1

• ConJnued evoluJon of JAX-‐RS API – All simple problems have already been solved…

• Performance – ReacJve Programming Model – Java SE 8 Streams – Non-‐blocking I/O

13

JSR 370


JAX-‐RS 2.1 (cont.)

•  Java EE Alignment – CDI Alignment – DeclaraJve Security Model – MVC 1.0 IntegraJon – JSONB 1.0 IntegraJon

•  Filling the Gaps – Server-‐Sent Events – Improved Hypermedia Support – CORS

14

JSR 370


MVC 1.0

• AcJon-‐based Model-‐View-‐Controller architecture • Glues together key Java EE technologies: – Model •  CDI, Bean ValidaJon, JPA

– View •  Facelets, JSP

– Controller •  Invent new technology? •  Leverage exisJng technologies such as JAX-‐RS, ... ?

JSR 371

15


JSF 2.3

•  SpecificaJon clarificaJons • CDI alignment – Ease of use e.g. @Inject – Removal of old injecJon provider

• Performance enhancements – Caching EL expressions were possible

• Use Java SE 8 where possible

JSR 372

16


JSF 2.3 (cont.)

• MVC alignment •  Shepherd EG driven features into spec – JSON ajax component rendering – State saving enhancements – Stateless enhancements – GET enhancements – …

JSR 372

17


Java EE Management API 2.0

• Update of JSR 77 • Define RESTful API for Java EE management – Incorporate all exisJng JSR 77 managed beans – Define event model using Server Sent Events – ConsideraJon will be given to mark the exisJng MEJB API as Proposed OpJonal

• Define RESTful API for applicaJon deployment – Focus on simple cases first – Deployment support integrated to same API with other Java EE management

JSR TBD

18


JSON-‐P 1.1

•  Support for JSON standards – JSON Pointer (RFC 6901) and JSON Patch (RFC 6902)

•  Support for ediJng/transformaJon on JsonArray and JsonObject – Add API for the current builders

•  Support JSON query in JavaSE 8 – Add helper classes and methods to construct Collectors
