New Tech Article: PrimeFaces in the Enterprise

PrimeFaces, a popular JavaServer Faces (JSF) UI framework, can be used to quickly develop sophisticated applications for the enterprise or for standard websites. The OTN tech article PrimeFaces in the Enterprise focuses on how to efficiently build data-driven applications for the enterprise. Developer Josh Juneau builds an enterprise application, making use of PrimeFaces to create a user-friendly, robust experience. He walks you through developing forms to input and update customer, job, and pool information for the fictional AcmePools company. See how PrimeFaces can be included in JSF applications to significantly increase the options available for your applications.

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!
