Get Involved with Java Standards!

Joining the Java Community Process is made easier with the new release of JSR 364. Now individuals can join as associates and won’t need to have their employers sign off on the participation, explains Heather VanCura in this interview. The long-criticized membership fee is also gone. Watch the interview and learn how you can participate as a JUG, individual or a company.  Provide feedback by sending email to admin@jcp.org or via the JSR 364 project page

NightHacking Tour in Japan

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.

New Java Champion Pratik Patel

Welcome New Java Champion Pratik Patel


Pratik Patel is a long time Java expert, advocate and community organizer. While working as a graduate student at the University of North Carolina’s SunSITE research lab (which was sponsored by Sun Microsystems), he learned about Java and was immediately hooked by the potential of the platform and the language. That year, in 1996, he co-authored the 2nd book on Java. The following year, he wrote the first book on enterprise Java. He went on to implement large-scale Java based systems in investment banking, health-care and telco in various places in the world including New York, London, and Hong Kong.

Starting in 2005, Pratik became involved with the Atlanta Java User’s Group (AJUG), and later became a board member. His work in bringing the world’s experts on Java technology to Atlanta have helped make DevNexus one of the largest community run Java centric conferences in the world. Around the same time, he started to share his deep knowledge of Java and the JVM to developers in the USA and around the world. He is a frequent speaker at the No Fluff Just Stuff tour and other Java-centric conferences. He also is the primary organizer of DevNexusJr, a venture that is part of AJUG to bring the joy of programming to the next generation of developers. Follow him at @prpatel

New Java Champion Henri Tremblay

Welcome the new Java Champion Henri Tremblay!

Henri Tremblay has been developing with Java since 1998. In 2003, he became a main contributor of  the EasyMock open source project and created the concept of class mocking. He also invented and coined the term "partial mocking". He is now the lead developer of EasyMock and Objenesis, both of which are projects used by numerous frameworks. Ojenesis is a technical project allowing class creation without calling the constructor. He has also contributed to many Java open source projects. He is currently helping on the JEP 260: Encapsulate Most Internal APIs.

Henri is also the founder of the PerfUG, a user group dedicated to performance. The group currently has more than 400 members. It recently received Java speakers including Kirk, Heinz, Richard Warburton and Jean-Philippe Bempel. He is now involved with the Montreal JUG. 

Henri is a frequent speaker at Java conferences. One of his JavaOne sessions was a hands-on lab with Java champions Heinz Kabutz, Kirk Pepperdine, Ben Evans and Martijn Verburg. Follow him @henri_tremblay

Java User Groups: Changing the World, One Line of Code at a Time!

What is the impact of user groups on their members, society and the extended Java community? In this article, Daniel deOliveira presents a detailed analysis of Java user groups, their governance and influence. Also known as Dr. JUG, Daniel is the founder of the Federal District Java Users Group (DFJUG) in Brazil, and is passionate about the benefits of Java user groups (JUGs).

Daniel shows the value of JUGs, which accrue not only from the core members of a JUG but also, perhaps surprisingly, from peripheral members and outsiders. In fact, he advises that "if you run into a problem and need solid information, important advice, or support, look for people in the core group, which is where the knowledge is clustered. But if you need fresh ideas or innovation, look for the people in the periphery."

He sees the power of JUGs as teaching machines and as forces for social good. "Teaching kids Java for free always receives the enthusiastic support of colleagues. Some groups "go the extra mile" by conducting educational activities in underprivileged communities or teaching Java to the deaf, the blind, and wheelchair users." Find out more insights about Java user groups in his article
