1998-2004 2005-2012 2013 - Future

MEETING DEVELOPER ENTERPRISE • Full implementations PRODUCTIVITY DEMANDS – GlassFish 4.x Java EE 7 – WildFly 8.x

– TMAX JEUS 8 . Batch . More annotated POJOs . Concurrency • . Less boilerplate code . JAX-RS . Simplified JMS Partial implementations . Cohesive integrated . WebSockets platform . JSON – WebLogic 12.1.3 . Servlet NIO

– WebSphere Liberty Profile Beta

Copyright © 2014, Oracle and/or its affiliates. All rights reserved. 8 Java EE 8 Themes • HTML5 / Web Tier Enhancements • Ease of Development / CDI alignment • Infrastructure for running in the Cloud • Java SE 8 alignment – Utilizing Java SE 8 new features

Java SE 8

Copyright © 2014, Oracle and/or its affiliates. All rights reserved. 9 HTML5 Support and Web Tier Enhancements • HTTP/2 support • Action‐based MVC • Server‐sent events – Part of HTML5 – By extending JAX-RS (already supported by Jersey) • JSON Binding – Similar to JAXB (already supported by MOXy) • JSON Processing enhancements – Track new standards JSON-Pointer and JSON-Patch

Copyright © 2014, Oracle and/or its affiliates. All rights reserved. 10 HTTP/2 Address the Limitations of HTTP • HTTP/2 expected as proposed standard from IETF this month • Reduce latency – Address the Head-of-Line blocking problem • Support parallelism – Without requiring multiple connections • Retain semantics of HTTP 1.1 • Define interaction with HTTP 1.x

Copyright © 2014, Oracle and/or its affiliates. All rights reserved. 11 HTTP/2 • Request/Response multiplexing over single connection – Fully bidirectional – Multiple streams • Stream prioritization • Server push • Binary framing • Header compression • Upgrade from HTTP 1.1

Copyright © 2014, Oracle and/or its affiliates. All rights reserved. 12 Servlet 4.0 HTTP/2 Features in Servlet API • Request/response multiplexing – Servlet request as HTTP/2 message • Stream prioritization – Add stream priority to HttpServletRequest • Server push • Upgrade from HTTP 1.1 • Binary framing – Hidden from API

Copyright © 2014, Oracle and/or its affiliates. All rights reserved. 13 MVC 1.0 JSR 371 • Action-based Model-View-Controller architecture – Vs. component-based like JSF, Wicket, Tapestry • Glues together key Java EE technologies: – Model • CDI, Bean Validation, JPA – View • Facelets, JSP – Controller • Leverage existing technologies such as JAX-RS, ... ?

Copyright © 2014, Oracle and/or its affiliates. All rights reserved. 14 Ease of Development and CDI alignment • Security interceptors • Simplified messaging through CDI-based “MDBs” • CDI improvements – Events: async, ordering, range (war, ear, server, cluster) – WebSocket scopes • Pruning of EJB 2.x client view and IIOP interoperability

Copyright © 2014, Oracle and/or its affiliates. All rights reserved. 15 CDI Interceptor for Authorization Java EE Security 1.0 @IsAuthorized("hasRoles('Manager') && schedule.officeHrs") void transferFunds();

@IsAuthorized("hasRoles('Manager') && hasAttribute('directReports', employee.id)") double getSalary(long employeeId);

@IsAuthorized(ruleSourceName="java:app/payrollAuthRules", rule="report") void displayReport();

Copyright © 2014, Oracle and/or its affiliates. All rights reserved. 16 Simplified messaging through CDI JMS 2.1 • New API to receive messages asynchronously • Alternative to message driven beans @RequestScoped • Simpler JMS annotations public class MyListenerComponent {

– Usable by any CDI bean @JMSListener(destinationLookup="myQueue") – No need for MessageListener @Transactional public void myCallback(Message message) { implementation ...... } }

Copyright © 2014, Oracle and/or its affiliates. All rights reserved. 17 Infrastructure Modernization For On-Premise and Cloud • Java EE Management 2.0 – REST-based APIs for Management and Deployment • Java EE Security 1.0: enhance portability, flexibility, ease-of-use – Authorization – Password aliasing – User management – Role mapping – Authentication – REST authentication

Copyright © 2014, Oracle and/or its affiliates. All rights reserved. 18 Java EE Management 2.0 • Update of JSR 77 (J2EE Management) • Define RESTful API to augment and/or replace current Management EJB APIs – Currently used OBJECT_NAME to become URL – Define CRUD operations for individual managed object – Server-sent events used for event support • Define RESTful API for application deployment – Focus on simple cases first – Deployment support integrated to same API with other Java EE management

Copyright © 2014, Oracle and/or its affiliates. All rights reserved. 19 Java EE Security 1.0 Password aliasing • Standardized syntax for password aliases – Avoids storing passwords in clear text in code, deployment descriptors and files @DataSourceDefinition( name="java:app/MyDataSource", className="com.example.MyDataSource", ... user="duke", password="${ALIAS=dukePassword}")

• Standardized secure credentials archive for bundling alias and password with the application – Used by platform as credential store for resolving alias

Copyright © 2014, Oracle and/or its affiliates. All rights reserved. 20 Java EE Security 1.0 User Management • Allow application to manage its own user and groups – Without need to access server configuration • Users stored in application-specified repository (e.g., LDAP) • User service manipulates users from user source
