Bruno Souza, Edson Yanaga, and Otávio Santana are touring European JUGs talking about DevOps, big data, currency API, CDI 2 and cloud scalability. The team is also interviewing Java Champions, renowned Java speakers and community leaders in their homes and at work. Watch the replay of those interviews
Welcome New Java Champion Mark Heckler!
Java Community Lead Stephen Chin and Freelancer Sebastian Daschner are touring Java User Groups in Japan. You can watch them live at NightHacking.
Stephen walks you through how to build your own retro handheld console that is powered by Java, runs on a Raspberry Pi, and is printed on a 3D printer. Some of the topics he covers along the journey include: hacking Java on the Raspberry Pi , rigging input devices with Pi4J, insane performance tuning on the JVM , why your boss needs to buy you a 3D printer! And, of course, your retro gaming mettle will be put to the test, so dust off your old 8 and 16 bit consoles! This presentation is about the most fun you can have while still legitimately calling this conference “work.”
Sebastian gives an introduction of RESTful web services with Hypermedia as the engine of application state, what the benefits and costs of using this approach are and show different approaches how to realize such REST services with JavaEE 7 and JAX-RS. Most of the time will be spent demonstrating different implementations (plain JavaEE 7, existing libraries, etc.) with live coding. The session is held in English.

Are you planning to use containers and microservices together? Bruno Souza and Elder Moraes introduce those topics in their article "Step-by-Step High Availability with Docker and Java EE". Using a simple example, they show how you can use Java EE with Docker as a powerful way to develop and deploy portable, scalable, highly available services.
Souza and Moraes use the following steps to illustrate how easily and quickly you can use Docker containers with a Java EE application:
Prepare for the Java SE 8 exam or upgrade your certification from any previous Java SE to Java SE 8. There are resources available, whether you are getting a certification for the first time or want to upgrade your certification.
