Java EE 7 Platforms

GlassFish

Java EE 7

Java EE 6

TomEE

Public


GlassFish 4.1 and WebLogic 12.1.3• Glassfish 4.1– Addressing security, must-fix and important bugs,– 800+ bugs fixed!– JDK 8 Support– Updates to projects: Jersey, Mojarra, WebSocket 1.1, Tyrus,

Grizzly, CDI 1.2, Weld 2.2

• WebLogic 12.1.3–WebSocket, JSON-P, JAX-RS 2, JPA 2.1– JDK 8 support– Server-Sent Events (SSE)–WebSocket fallback– Improved Maven support, official Docker images

Public


Java EE in Action

http://cargotracker.java.net

Public


JMS 2• API modernization– Dependency injection– Fluent APIs– Intelligent defaults– Unchecked exceptions

• New features– Delivery delay, async send

• Platform alignment–MDB activation properties, JMS resource definition, default

JMS resources

Public


Java API for WebSocket• High level API for HTML 5 WebSockets– Full-duplex TCP-like communication on the Web utilizing HTTP

• Both client and server-side (Java SE and Java EE)

• Both declarative and programmatic

• Pluggable and extensible

Public


Java API for JSON Processing• Low level API to parse, generate, transform, query

JSON– JSON equivalent of JAXP

• Object Model and Streaming API– Similar to DOM and StAX

• Binding JSON to Java objects forthcoming– JSON equivalent of JAXB

Public


Bean Validation 1.1• Method constraints– Very useful for JAX-RS and WebSocket

• CDI Alignment– All Bean Validation artifacts now injection capable

• EL 3 integration– More expressive validation messages

Public


JAX-RS 2• Client API

• Message Filters & Entity Interceptors– Servlet filters and CDI interceptors for JAX-RS

• Asynchronous Processing – Server & Client

• Hypermedia support– Transitional and structural links

• Content negotiation

Public


JPA 2.1• Schema generation

• Stored procedures

• Unsynchronized persistence contexts

• Entity Graphs

• Entity converters

Public


JSF 2.2• HTML5 Support– Pass-through elements and attributes

• Managed beans deprecated/CDI alignment–@ViewScoped for CDI

• @FlowScoped

• Stateless views

• Resource library contracts

• View actions

• File upload component

Public


Batch Applications for the Java Platform • API for robust batch processing targeted to Java EE,

Java SE

• Common architecture–Operator, repository, job, step, reader-processor-writer

pattern

• Common features– Chunking, check-pointing, transactions, retries, exceptions,

workflow, parallelism

Public


Concurrency Utilities for Java EE • Provides simple, safe API for concurrency in Java EE

• Builds on Java SE concurrency–ManageExecutorService–ManagedScheduledExecutorService–ManagedThreadFactory

• Relatively low-level API

• Important enabler for Java EE ecosystem

Public


Concurrency Utilities for Java EE Managed Task Executor

public class TestServlet extends HTTPServlet { @Resource ManagedExecutorService executor;

Future future = executor.submit(new MyTask());

class MyTask implements Runnable { public void run() { ... // Task logic } }}

Public


Yet More…• JTA 1.2–@Transactional, @TransactionScoped

• EL 3.0– Standalone API, lambda expressions, collections, operators

• Servlet 3.1– Non-blocking I/O, upgrade to WebSocket, security

• CDI 1.1– Global enablement, @AroundConstruct, @Vetoed

• EJB 3.2– Truncating CMP/BMP

Public

https://java.net/downloads/javaee-spec/JavaEE8_Community_Survey_Results.pdf

https://blogs.oracle.com/ldemichiel/entry/results_from_the_java_ee

Public


Java EE 8 Possibilities• Web Standards/HTML5 Alignment– HTTP2, SSE, JSON-B, JSON-P, action-oriented web framework,

hypermedia

• Cloud– Simple security providers, REST management/monitoring

• CDI Alignment– CDI 2, EJB services outside EJB, security interceptors, EJB

pruning

• Enterprise– JCache, Configuration, JMS

• Java SE 8 alignment
