Performance is based on measurements and projections
using standard IBM benchmarks in a controlled environment. The
actual throughput or performance that any user will
experience will vary depending upon many factors, including
considerations such as the amount of multiprogramming in
the user’s job stream, the I/O configuration, the storage
configuration, and the workload processed. Therefore, no
assurance can be given that an individual user will achieve results
similar to those stated here.

9. Java EE 8 Content
(as of Feb 2017)
9 3/19/17

10. Security 1.0 (JSR 375)
• Scaled back from original content in order to make Java EE 8
dates… The following items are still in plan…
• API for Authentication Mechanism
• API for Identity Store
• API for Security Context (still being discussed)
• Goals
• Plug the portability holes
• Modernize – Utilize CDI, POJOs, EL
• App Developer Friendly – Common security configurations and
annotation defaults
• New Reference Impl – Soteria
• Should work on existing Java EE 7 Impls…
3/19/1710

11. Servlet 4.0 (JSR 369)
• Support for HTTP/2*
• Request/response multiplexing
• Stream prioritization
• Server push promise request
• Major upgrade from HTTP 1.0, but still compatible with 1.0 and 1.1
• Smaller community-requested improvements (JIRA issues)
• Support for request.getMapping so an application can determine which
mapping was used to select the resource being called
• Support for specifying a default context for the application in web.xml
• Support for specifying default request/response character encoding in
web.xml
3/19/1711

12. Servlet 4.0 (JSR 369) - cont
• *HTTP/2 hiccup
• Currently, the ALPN dependency is only provided in Java SE 9
• Java EE 8 only requires Java SE 8
• Disconnect that needs to be ironed out…
• Current thought is to backport the required APIs to Java SE 8 in the jdk.* package
• Immediately mark these as ”deprecated” so that they are not accidentally used in
Java SE 9
• But, no official work item has been logged with the Oracle JDK to resolve this yet…
3/19/1712

13. CDI 2.0 (JSR 365)
• Core CDI, Java SE CDI, and Java EE CDI
• Ordering of observers based on priorities
void afterLogin(@Observes @Priority(javax.interceptor.Interceptor.Priority.APPLICATION)
LoggedInEvent event) { ... }
• Asynchronous Events
@Inject Event<LoggedInEvent> loggedInEvent;
public void login() {
...
loggedInEvent.fireAsync( new LoggedInEvent(user) );
}
• Introduced Configurator Interfaces
For example, AnnotedTypeConfigurator SPI for AnnotatedType configuration
• Built-in annotation literals, such as Default
• Utilize Java 8 language features – streams, lambdas, etc
3/19/1713

14. Bean Validation 2.0 (JSR 380)
• Container element validation via annotations on type arguments of
generics.
• List<@Max(1) Integer> postiveNumbers;
• Map<@Valid CustomerType, @Valid Customer>
customersByType;
• Cascaded validation of arrarys, iterables, and maps.
• @Valid List<Address> addresses;
• New date/time data types built-in constraints of @Past and @Future
or custom temporal constraints can now be used for temporal
validation.
• Other new features include:
• built-in constraints are now marked as repeatable
• parameter names for method validation are retrieved through reflection
• support for JavaFX property types
• java.util.Optional support
3/19/1714

15. JSON-B 1.0 (JSR 367)
• Converts Java objects to and from JSON
• Natural follow up to JSON-P: closes the JSON support gap
• JAXB-like API to marshal/unmarshal Java objects to/from JSON
• javax.json.bind
• Default mapping for basic Java types, including collections and
arrays
• Optional overrides for customized mappings
public class Employee {
public String firstName;
public String lastName;
@JsonbProperty(value = "ssn")
public long taxId;
}
Jsonb jsonb = JsonbBuilder.create();
Employee employee =
jsonb.fromJson("{firstName:"Kevin",lastName:"Sutter",ssn:123456789}",
Employee.class);
String json = jsonb.toJson(employee);3/19/1715

16. JSON-P 1.1 (JSR 374)
• Keep JSON-P spec up-to-date and relevant
• And, consistent with JSON-B 1.0 (JSR 367)
• Support for IETF standards on JSON Pointer, JSON Patch, and
JSON Merge
• rfc6901, rfc6902, and rfc7396, respectively
• Add Editing operations to JsonObject and JsonArray
• add all, remove, set at index, add at index operations
• Helper classes and methods to better utilize Java SE 8’s stream
operations
3/19/1716

17. JAX-RS 2.1 (JSR 370)
• Server-sent events
• Reactive Client API
• Needed for both Server-sent event processing as well as improving the
jax-rs asynchronous client support.
• Non-blocking I/O in providers (filters, interceptors…)
• Utilize Java SE 8 language features such as lambdas
• Scaled back a bit from original jax-rs 2.1 intent…
• Hypermedia API Enhancements
• Support for declarative security
• JAX-RS resource classes as controllers (for MVC, which was dropped)
3/19/1717

18. JSF 2.3 (JSR 372)
• WebSocket Integration
• Multi-field validation
• Java 8 SE Time/Date support
• CDI integration enhancements
• Use CDI for evaluation of JSF specific EL implicit Objects
• Deprecate javax.faces.bean. Support @Inject on JSF specific artifacts
• CDI Replacement for @ManagedProperty. See javadocs for
javax.faces.annotation.ManagedProperty.
http://arjan-tijms.omnifaces.org/p/jsf-23.html
3/19/1718

19. JPA 2.2 (JSR ???)
• Pretty minor – Maintenance Release (MR) ???
• Support for Java SE 8 language updates
• Repeating annotations
• Java Date/Time support
• Stream support in queries
3/19/1719

20. Other minor JSR updates…
• JavaMail 1.6 (JSR 919)

• Common Annotations 1.3 (JSR 250)
• Very common to update Common Annotations with every Java EE
release
• Interceptors 1.2 rev A (JSR 318)
• No functional changes, just cleanup and clarifications
