JSON Processing 1.0
▪ API to parse and generate JSON ▪ Streaming API (javax.json.stream)
– Low-level, efficient way to parse/generate JSON – Similar to StAX API in XML world
▪ Object model API (javax.json) – Simple, easy to use high-level API – Similar to DOM API in XML world
Copyright © 2014, Oracle and/or its affiliates. All rights reserved.!9
JSON Processing 1.0
▪ Created using – Json.createParser(…)!– Json.createParserFactory().createParser(…)!
▪ Parses JSON in streaming way from input sources Event event = parser.next(); // START_OBJECT!event = parser.next(); // KEY_NAME!event = parser.next(); // VALUE_STRING!
▪ Parser state events – START_OBJECT, END_OBJECT, START_ARRAY, END_ARRAY, KEY_NAME, VALUE_STRING, VALUE_NUMBER, …

▪ Protocol Upgrade ▪ Non-blocking I/O ▪ Miscellaneous
▪ Security ▪ Upload ▪…
JSR 340
Copyright © 2014, Oracle and/or its affiliates. All rights reserved.!39
Alignment and Simplification of Managed Beans
▪ CDI is core component model ▪ CDI enabled by default ▪ Expanded use of CDI Interceptors
– Transactional interceptors – Method-level validation interceptors
▪ New CDI scopes: @TransactionScoped, @FlowScoped
Cohesive, integrated model
Java EE 7
Copyright © 2014, Oracle and/or its affiliates. All rights reserved.!40
Managed Bean Alignment
▪ CDI injection and CDI interceptors apply to all Java EE components and related managed classes when CDI is enabled
▪ CDI is enabled by default in implicit bean archives – Use of CDI bean-defining annotations (@SessionScoped, @Dependent,…) and session beans result in implicit bean archives ▪ Library jars, EJB jars, WEB-INF/classes
– beans.xml not required
Expanded use of CDI
Copyright © 2014, Oracle and/or its affiliates. All rights reserved.!41
Transactional Interceptors
@Transactional(rollbackOn={SQLException.class},! dontRollbackOn={SQLWarning.class})!public class ShoppingCart {…}!…!!@Inherited!@InterceptorBinding!@Target({TYPE, METHOD}) @Retention(RUNTIME)!public @interface Transactional {! TxType value() default TxType.REQUIRED;! Class[] rollbackOn() default {};! Class[] dontRollbackOn() default {};!}
Annotations and semantics defined in JTA 1.2
Copyright © 2014, Oracle and/or its affiliates. All rights reserved.!42
Bean Validation 1.1 Method-level Validation
@Stateless!public class OrderService {! …! @ValidOrder! public Order placeOrder(! @NotNull String productName,! @Max(10) int quantity,! @NotNull String customerName,! @Address String customerAddress) {! …! }!}
Via CDI Interceptors
Copyright © 2014, Oracle and/or its affiliates. All rights reserved.!43
Interceptor Ordering
▪ Interceptor.Priority.PLATFORM_BEFORE = 0 – Platform-defined interceptors to be executed at beginning of interceptor chain – Transactional interceptors: Interceptor.Priority.PLATFORM_BEFORE+200
▪ Interceptor.Priority.LIBRARY_BEFORE = 1000 – Intended for use by extension libraries
▪ Interceptor.Priority.APPLICATION = 2000 – Intended for application-defined interceptors
▪ Interceptor.Priority.LIBRARY_AFTER = 3000 ▪ Interceptor.Priority.PLATFORM_AFTER = 4000
– Bean Validation defined interceptors: Interceptor.Priority.PLATFORM_AFTER+800
Well-defined priority ordering
Copyright © 2014, Oracle and/or its affiliates. All rights reserved.!44
Resource Definition Metadata
▪ Specifies resources needed by application – Enhances configurability in Java EE 7 apps – Facilitates provisioning in cloud environments – Java EE 6 introduced DataSourceDefinition
!@DataSourceDefinition (! name=“java:app/jdbc/myDB”,! className=“oracle.jdbc.pool.OracleDataSource”,! isolationLevel=TRANSACTION_REPEATABLE_READ, initialPoolSize=5)!!@Stateless public class MySessionBean {!@Resource(lookup=“java:app/jdbc/myDB”) DataSource my DB;!…!}
Copyright © 2014, Oracle and/or its affiliates. All rights reserved.!45
Resource Definition Metadata
▪ Java EE 7 adds: – JMSConnectionFactoryDefinition!– JMSDestinationDefinition!– MailSessionDefinition!– ConnectionFactoryDefinition!– AdministeredObjectDefinition
Copyright © 2014, Oracle and/or its affiliates. All rights reserved.!46
Default Resources
▪ JDBC/JPA – java:comp/DefaultDataSource!
▪ JMS – java:comp/DefaultJMSConnectionFactory!
▪ Concurrency Utilities – java:comp/DefaultManagedExecutorService!– java:comp/DefaultManagedScheduledExecutorService!– java:comp/DefaultManagedThreadFactory!– java:comp/DefaultManagedContextService
Preconfigured resources for use by application
Copyright © 2014, Oracle and/or its affiliates. All rights reserved.!47
Simplification through Pruning
▪ Process defined in Java EE 6 – Platform version N defines feature as “Proposed Optional” – Platform version N+1 determines whether to make feature Optional
▪ Optional APIs as of Java EE 7 – EJB Entity Beans (CMP, BMP, EJB QL) – JAX-RPC – JAXR – Deployment (JSR 88)
Copyright © 2014, Oracle and/or its affiliates. All rights reserved.!48
Java Message Service 2.0
▪ Less code, less boilerplate ▪ Fewer objects to manage ▪ Increased developer productivity ▪ “Classic API” has also been improved
New JMS Simplified API targeted at ease of development
Copyright © 2014, Oracle and/or its affiliates. All rights reserved.!49
JMS 2.0
▪ New JMSContext interface ▪ Use of CDI injection; new TransactionScope ▪ AutoCloseable JMSContext, Connection, Session, … ▪ Use of runtime exceptions ▪ Method chaining on JMSProducer ▪ Simplified message sending
Simplifications include….

Batch Applications for the Java Platform 1.0
▪ Designed for non-interactive, bulk-oriented and long-running tasks ▪ Sequential, parallel, and/or decision-based batch execution ▪ Processing styles
– Item-oriented (“chunked”) – Task-oriented (“batchlet”)
Copyright © 2014, Oracle and/or its affiliates. All rights reserved.!57
Batch 1.0
▪ Job : Entire batch process – Defined through XML Job Specification Language
▪ Step : Independent, sequential phase of a job ▪ JobOperator : Interface for managing job processing ▪ JobRepository : Information about past and present jobs
Key concepts
Job Repository
Job Operator Job StepItemReader
ItemWriter
ItemProcessor
Copyright © 2014, Oracle and/or its affiliates. All rights reserved.!58
Batch 1.0
▪ Chunked : Item-oriented processing – ItemReader/ItemProcessor/ItemWriter pattern – Configurable checkpointing and transactions
