Devoxx 2014 Vive La (Digital) Révolution!

Last week's Devoxx France conference in Paris was sold out months in advance. The conference is part of the Devoxx family and is organized by the Paris JUG for the francophone developer community.  

The conference provided an array of technical sessions, including conference sessions, hands-on labs, university sessions,  quickies, tools-in-action and birds-of-a-feather (BoF) that will become available on Parleys in coming weeks. The broad range of topics touched on Agile and DevOps methodologies, Web, HTML5, mobile, startups, cloud, Big Data, Groovy, Ceylon, Java SE and Java EE.  Senior engineer Paul Sandoz presented Java 8 lambdas in the stream, which is one of the main features of Java 8. The new feature is designed to enable bulk data. Professor José Paumard presented 50 new things that you could do with Java 8. He discussed ConcurrentHashMap, the new HashMap and Date & Time APi as well as small improvements that ease development. Not everyone will implement the lambdas right away, he said, but with Java 8 they will still be able to benefit from the new version. Java Evangelist Stephen Chin demonstrated the full power of Java 8 with lambdas running on Raspberry Pi, PandaBoard, the Lego Mindstorms EV3 and other embedded devices during his university session. 

The keynote speakers echoed this year's theme of "born to be" a developer in the digital era. They explained how developers have a strategic role and are makers of the digital revolution. For example, entrepreneur Kwam Yamgnane considers that, as craftsmen in the IT trade, the developer's job goes beyond coding to collaboration with other disciplines and understanding not just the direction of the product but also of their company and the industry. With this understanding, developers need to be creative and agile to build better products, explains senior engineer Geert Bevin. They can use the same principal to build their career and find their passion. 

The second topic of the keynote was about engineering becoming more mainstream.  With the advent of the digital revolution, everyone needs to learn about technology because of its impact on our daily lives, on our careers and on new business creation, explains INRIA researcher Serge Abiteboul. Enterpreneur Henri Fournet is training beginners in programming and business acumen at Simplon, a successful year old educational company serving low income neighborhoods. Directors Dominique Van Deth and Danny Gooris at Oracle discussed the shortage of engineers today. In order to fill out the gap, Oracle trains high school and university teachers in Java programming for free. 

In addition, there were several activities where developers could collaborate, code or just explore. At the hackergarten, developers and open source committers contributed to a dozen of open source projects.  At the future lab and hackathons, there were a number of homemade and fun projects. Attendees could learn and change the interface of JavaFX games. A robotic xylophone was controlled by Raspberry Pi and Arduino. Wafting dry-ice fog exposed the green beams of a musical light show. You could fly the Crazyflie Quadcopter and meet the development team. Stay tuned for the video made by the Devoxx France team with the Crazyflie strafing the crowd during the keynote and meet and greet reception. The Nao robot was programmed onsite to dance to M.J.'s Thriller and other music.  Home automation applications controlled temperature, water heater and lights.  At the Code-Story, experts coded applications in front of the audience. For the third year,  the Devops Mercenaries presented tools, expert accounts, and guidelines for engineering teams to implement the methodology. More focused on entrepreneurship was the 'afternoon of deciders' where developers and industry leaders met to discuss big data, as well as Seed Networking, a speed dating session between entrepreneurs and developers. Devoxx4Kids welcomed a dozen children to learn programming with the Nao robot and other programming tools like Scratch and Greenfoot. 

Join us next at Devoxx UK June 12 and 13 in London. This is going to be another amazing Devoxx experience!

Technical Article: RESTful GlassFish Monitoring and Management

In this new OTN technical article, RESTful GlassFish Monitoring and Management, Java EE expert Adam Bien shows you how to exploit the built-in monitoring and management capabilities of GlassFish to automate application deployment and gain insight into application performance.

"IT is all about streamlining and automation, so it is somewhat ironic that we developers still tolerate repetitive and boring manual tasks, such as deployment," Bien explains. "Also, our ignorance about easily accessible information for application servers, such as monitoring data, is surprising" he notes.

Application servers have emitted useful monitoring data and provided basic management capabilities for years, but both capabilities have been ignored. The DevOps movement is making these built-in monitoring and management capabilities interesting again. 

The article describes the GlassFish management API, which allows you to manipulate the GlassFish application server's configuration, including its monitoring capabilities. It also describes the GlassFish monitoring API, which provides a read-only facility for accessing the Java Virtual Machine (JVM), the GlassFish application server, and the GlassFish application server's metrics and counters.

Technical Article: JavaFX Integration Strategies

"You will rarely find isolated applications in the enterprise," says Adam Bien in the new OTN technical article entitled JavaFX Integration Strategies. Instead, an enterprise desktop application renders and manipulates the data of one or more back-end services exposed by an application server. This article focuses on the integration of Java EE services with JavaFX applications. It discusses synchronous and asynchronous communication with a JavaEE backend. LightFish and LightView were used as examples.

Author Adam Bien is a Java Champion, architect and Java developer. He is an Expert Group member for the Java EE 6 and 7, EJB 3.X, JAX-RS, and JPA 2.X JSRs.  He is the author of Real World Java EE Patterns—Rethinking Best Practices and Real World Java EE Night Hacks—Dissecting the Business Tier, and all around good guy.

GlassFish and JavaEE Roadmap Update

As announced at JavaOne, GlassFish Server Open Source Edition 4.1 is scheduled for 2014. 
Oracle is planning updates as needed to GlassFish Server Open Source Edition, which is commercially unsupported
. Oracle has announced the following updates to the GlassFish roadmap:

  • The trunk will eventually transition to GlassFish Server Open Source Edition 5 as a Java EE 8 implementation. 
The Java EE 8 Reference Implementation will be derived from GlassFish Server Open Source Edition 5. This replicates what has been done in past Java EE and GlassFish Server releases.
  • Oracle will no longer release future major releases of Oracle GlassFish Server with commercial support – specifically Oracle GlassFish Server 4.x with commercial Java EE 7 support will not be released.
Commercial Java EE 7 support will be provided from WebLogic Server.
  • Oracle GlassFish Server will not be releasing a 4.x commercial version.


Oracle is committed to the future of Java EE. Java EE 7 has been released and planning for Java EE 8 has begun. GlassFish Server Open Source Edition continues to be the strategic foundation for Java EE reference implementation going forward. The primary role of GlassFish Server Open Source Edition has been, and continues to be, driving adoption of the latest release of the Java Platform, Enterprise Edition. 

For more information, read Java EE and GlassFish Server Roadmap Update blog on the The Aquarium.

Java EE 7 Essentials Book by Arun Gupta

The new book Java EE 7 Essentials by Java Evangelist Arun Gupta has recently been published. Arun said "The developers around the world have been really excited trying the new and updated technologies in Java EE 7. Newer technologies like WebSocket, JSON Processing, Batch, and Concurrency continue to keep the platform innovative and meet demands of enterprise developers."

This book provides a code-intensive overview of the key specifications in the Java EE 7 platform (one specification per chapter). The main concepts from the different specifications are explained using simple code samples. All the associated code is available on github.

A significant part of this book is derived from his early book, the Java EE 6 Pocket Guide. New chapters have been added to cover all the new technologies in the platform - WebSocket 1.0, Batch 1.0, JSON-P 1.0, and Concurrency 1.0. New sections have been added or existing sections updated to reflect the changes in the platform. If you have read the Java EE 6 Pocket Guide, then you can read this book at a much faster pace; otherwise, you can read this book from beginning to end. Alternatively, you can read specific chapters based upon your interest.

The book also contains self-paced instructions on how to build an end-to-end Java EE application using NetBeans IDE.

Learn more about the book from Java Spotlight podcast #143.

If you are attending JavaOne in San Francisco, O'Reilly has arranged a book signing at their booth on Tuesday, Sep 24, 2pm. The book will also be available at JavaOne bookstore.

This book is available from the following websites:

Arun asked that if get the book, please post a review on your blog or here.

Java EE 7: JSRs That Make You Powerful

You've heard that Java EE 7 makes it easier to code, to create scalable, dynamic HTML 5 web apps, and much more. What does that mean, really? Here's how you can dig into details:  

1) Download the Java EE 7 SDK.

2) Watch these 15 - 20 minute technical overviews of the new JSRs. They are available on the Java EE 7 Launch Technical Breakouts playlist.

We hope this makes you feel ready to take advantage of all power that Java EE 7 provides.

Scalable, Dynamic HTML5
JSON JSON is a lightweight data exchange format used increasingly in RESTful Web services by highly visible Websites (Facebook, Twitter, Amazon, and the like). This webinar shows how JSR 353, Java API for JSON Processing, can be used to process JSON.
WebSocket 1.0 The Java API for WebSocket is a wholly new technology for the Java EE platform. This webinar looks at two core example applications - a simple Echo application with both annotated and programmatic WebSocket endpoints, and a chat application with both a browser and a Java client.
JAX-RS 2 JAX-RS is the Java API for building RESTful web services. This webinar focuses on the new and exciting features introduced in JAX-RS 2.0 including the client API, filters and entity interceptors, asynchronous processing, and hypermedia. These new features increase ease of use, reduce application development time, and increase application portability.
JSF 2.2 HTML5 and "ease of development" are two key themes of JavaEE 7. This 20 minute webinar shows how JSF 2.2 contributes to these themes. Among other things, we'll look at how HTML5 Friendly Markup allows authoring 100% compatible JSF pages that are also 100% HTML5. And how Resource Library Contracts and Faces Flows enable modularizing the appearance and functionality of the views in your JSF web application.
