[DevoxxBE2013] Part 1: Java EE 7: What’s New in the Java EE Platform
Antonio Goncalves and Arun Gupta, luminaries in Java EE advocacy, deliver a comprehensive exploration of Java EE 7’s advancements, blending simplification with expanded capabilities. Antonio, a senior architect and author of Beginning Java EE 6 Platform with GlassFish 3, collaborates with Arun, Red Hat’s Director of Developer Advocacy and former Java EE pioneer at Sun Microsystems, to unveil WebSocket, JSON processing, and enhanced CDI and JTA features. Their session, rich with demos, highlights how these innovations bolster HTML5 support and streamline enterprise development.
Java EE 7, they assert, refines container services while embracing modern web paradigms. From WebSocket’s real-time communication to CDI’s unified bean management, they showcase practical integrations, ensuring developers can craft scalable, responsive applications.
WebSocket for Real-Time Communication
Antonio introduces WebSocket, a cornerstone for HTML5’s bidirectional connectivity. He demonstrates @ServerEndpoint-annotated classes, crafting a chat application where messages flow instantly, bypassing HTTP’s overhead.
Arun details encoders/decoders, transforming POJOs to wire-ready text or binary frames, streamlining data exchange for real-time apps like live dashboards.
JSON Processing and JAX-RS Enhancements
Arun explores JSON-P (JSR 353), parsing and generating JSON with a fluid API. He demos building JSON objects from POJOs, integrating with JAX-RS’s HTTP client for seamless RESTful interactions.
This synergy, Antonio notes, equips developers to handle data-driven web applications, aligning with HTML5’s data-centric demands.
CDI and Managed Bean Alignment
Antonio unveils CDI’s evolution, unifying managed beans with injectable interceptors. He showcases constructor injection and method-level validation, simplifying dependency management across EJBs and servlets.
Arun highlights JTA’s declarative transactions, enabling @Transactional annotations to streamline database operations, reducing boilerplate.
Simplified JMS and Batch Processing
Arun introduces JMS 2.0’s simplified APIs, demonstrating streamlined message publishing. The new Batch API (JSR 352), Antonio adds, orchestrates chunk-based processing for large datasets, with demos showcasing job definitions.
These enhancements, they conclude, enhance usability, pruning legacy APIs while empowering enterprise scalability.
Resource Definitions and Community Engagement
Antonio details expanded resource definitions, configuring data sources via annotations. Arun encourages JCP involvement, noting Java EE 8’s community-driven roadmap.
Their demos—leveraging GlassFish—illustrate practical adoption, inviting developers to shape future specifications.

Guillaume shares experiences with Groovy’s functional paradigms, drawing parallels to Java’s modernization. Critiques address Oracle’s stewardship post-Sun acquisition, with concerns over delayed releases and community involvement.
Build tools spark debate: Maven’s ubiquity contrasts with Gradle’s rising popularity for Android and flexibility. Antonio advocates for tool-agnostic approaches, while Emmanuel warns of migration costs. The panel concurs on the need for better dependency management, citing transitive conflicts as persistent issues.
Cloud and DevOps trends feature prominently, with reflections on PaaS like Cloud Foundry. Vincent emphasizes automation’s impact on deployment cycles, reducing manual interventions. Security vulnerabilities, like recent Java exploits, prompt calls for vigilant updates and sandboxing.
Community Engagement and Event Reflections
Devoxx France’s organization draws praise for inclusivity and speaker diversity. Arnaud recounts logistical feats—managing 1,000 attendees with volunteer support—highlighting French JUGs’ collaborative spirit. Comparisons to international Devoxx events note unique cultural flavors, like extended lunches fostering networking.
Audience polls reveal demographics: predominantly male, with calls for greater female participation. The panel encourages involvement in JUGs and conferences, citing benefits for skill-sharing and career growth. Humorous anecdotes, like Antonio’s “chouchou” moniker from keynote interactions, lighten the mood, reinforcing the podcast’s approachable style.

Abstract
This article examines the opening keynote of Devoxx France 2013, delivered by Nicolas Martignole, Antonio Goncalves, Zouheir Cadi, and José Paumard. It contextualizes the event’s growth, organizational challenges, and community focus, analyzing session selection, special events, and thematic keynotes on past, present, and future of the industry. The discussion highlights transparency in call-for-papers, sponsor contributions, and efforts to engage diverse audiences, underscoring Devoxx’s role in fostering Java and broader tech ecosystems.
Event Overview and Growth Trajectory
The keynote commences with warm welcomes, acknowledging the team’s efforts in hosting Devoxx France 2013, a three-day event with 180 speakers, 75% French-language content. Martignole notes the expansion from 1,250 attendees in the inaugural edition to 1,400, a 220-person increase, signaling strong community interest. This growth mirrors the Devoxx family’s international success: 3,500 in Belgium and 500 for the UK’s debut, organized in just four months.
A satisfaction survey from the previous year, with 301 responses, informs improvements. Despite its length (81% found it too long, 18% much too long), it guides refinements, with Goncalves promising quality control for future iterations. The emphasis on constructive feedback, especially negatives, reflects a commitment to attendee-driven evolution.
Practical details include a free “Meet and Greet” evening with wine and cheese, sponsored by SonarSource, Atlassian, and CloudBees, running until 22:00. Six rooms host sessions, with overflow managed by red-vested volunteers for safety. All talks are recorded on Parleys.com, alleviating concerns about missing content. Community integration is highlighted, welcoming groups like Paris JS and Scala User Group.
Organizational Transparency and Session Selection
Transparency in the call-for-papers process is a focal point. Opened November 20 and closed January 31, it garnered 572 submissions, accepting only 162 due to venue constraints. Conferences (50-minute slots) saw 320 proposals, with 74 accepted; 14 allocated to premium sponsors, leaving 60 for general selection – an 82% rejection rate.
A 10-person team, including volunteers, rigorously evaluated submissions, using notes (0-5 scale), discussions, pizzas, and color-coded Post-its. Goncalves humorously notes resorting to a cat for ties, underscoring the process’s seriousness despite challenges. Rejected speakers are encouraged to reapply or present at local JUGs, emphasizing inclusivity.
The keynote theme – past, present, future – features speakers like Clarisse Herrenschmidt on writing history, Martin Odersky on objects and functionals, Alexis Moussine-Pouchkine on Java’s trajectory, and Habib Guergachi on web architectures. Odersky’s evening BoF is noted for Scala enthusiasts.
Special Initiatives and Community Engagement
Unique events differentiate Devoxx: “Devoxx for Kids,” led by Audrey Neveux, introduced 70 children to programming via robots the previous day, aiming to demystify parents’ professions. Though not repeatable annually due to school changes, it inspires future iterations alongside Belgium’s multilingual versions.
“Open Source Hacking” with Brice Dutheil and Mathieu Ancelin offers hands-on contribution. The “Afternoon for Decision-Makers,” from 14:00-18:15, mixes genres with CIOs discussing cloud, prepared by Arnaud Héritier. Reserved seats accommodate hard-to-book executives, but it’s open to all.
“Code Story,” by David Gageot and Jean-Laurent de Morlhon, features full-day live coding in a basement room. “Mercenaries of DevOps,” with Pierre-Antoine Grisoni, Henry Gomez, and others, explores native packaging and Kanban boards the next day.
Sponsors receive gratitude: premium partners enable affordable tickets; Oxiane handles training for over half attendees, managing complex dossiers. Medium and base sponsors filled slots quickly, with full exhibition halls praised for embodying Devoxx spirit.
In summation, the keynote reinforces Devoxx as a collaborative hub, blending education, networking, and innovation to advance the Java community and beyond.
