Java Tsunami on the Thames

London prepares for a surge of developer brainpower during the Devoxx UK conference on Tuesday and Wednesday, March 26th and 27th. Meet & Greet, global Java community, and Hackergarten are nice add-ons. Don't miss it - Register today

The fun really starts on Monday evening with an attendee Meet & Greet where attendees can relax, grab a drink and something to eat and, of course, meet fellow attendees and the speakers. 

In addition to U.K speakers, many international guests are scheduled, notably from the US. Twenty-eight user groups from across Europe are attending too. A veritable army of experts will be on hand to share their expertise with Devoxx attendees.  

Hackergarten takes place during the conference. There's no time limit; participants can stay and code for as long as they want. Just bring a laptop and write a plugin, a tutorial, a small feature, or a bug fix for a project that interests you alongside several open-source experts willing to share their knowledge. The organizers of two community projects called Adopt-a-JSR and Adopt Open JDK will be there to explain how to contribute to the future Java releases.

Register Now for Devoxx UK and Devoxx France 2013

There's only a little over a month to go before Devoxx UK on March 26 and 27 in London and Devoxx France on March 27 to 29 in Paris. The conference schedules are up and space is tight, so register today before they are sold out!

"Cloud, architecture and security" is a new conference track this year. Other tracks are Java SE, methodologies, Java EE, web & big data, new languages on the JVM, and future Devoxx. Developers will get a shot at peer discussions in Bird-of-a-Feathers, learn tips and tricks during quickies and get in-depth technical information in hour-long talks or in the three hour hands-on-labs.  "You could learn something that will help in your day job. Maybe it's a better use of patterns, technologies or methodologies you're utilizing right now" explains Trisha Gee, one of the Devoxx organizers

The conference also presents great networking opportunities with leaders in the Java community and renowned speakers who wrote popular technical books. Some of those well-known speakers are Kirk Pepperdine, Peter Pilgrim, Stephen Chin, Arun Gupta, and Markus Eisele, just to name a few.

FOSDEM 2013



The annual Free Open-Source Developers' European Meeting took place last weekend in Belgium. The free event brought together 5,000 hackers from the open source community. There were 477 speakers and 488 sessions with a mix of keynotes, lightning talks, certification exams and developer rooms talks.


Tasha Carl, Java architect and the leader of the Brussels Java user group, wrote a blog about FOSDEM and the Free Java developer room. She mentioned Java talks and posted pictures making you feel as if you were there. "The Free Java dev room at FOSDEM is since many years the biggest OpenJDK meet-up around. You can not only see, but really high-five celebrities like – this year – Mark Reinhold, Chief Architect of the Java Platform Group at Oracle, Sean Coffey, Oracle JDK engineer and maintainer of OpenJDK 7u, Steve Poole, developer and evangelist working since ever  for IBM on the JVM, Simon Phipps, Andrew Haley, Charles Nutter, JRuby lead developer speaking about InvokeDynamic,…" she commented.


In another blog, Mani mentioned that "the OpenJDK topic has got massive coverage with 17 speakers, speaking and holding events covering various topics." Java community leaders including Martijn Verburg and Ben Evans were involved in the Java track. In addition to Brussels JUG, members of LJC JUG, CEJUG and others participated at the event.


In her blog, Heather VanCura shares the Java Community Process (JCP) presentation titled "JCP State of the Nation and Future Directions," as well as links to JCP.Next and the community program Adopt-a-JSR programs.

The JCP Evolution!

Recent changes to the Java Community Process (JCP) program "focus on the way the organization itself is structured and organized" explained Patrick in this interview.  The changes will result from the implementation of three Java Specification Requests (JSRs). The first JSR, the JSR 348, makes the process more open and transparent to facilitate developers' participation. It was released a year ago and Heather witnessed increased transparency in projects,  additional participation and a simplified release process. "They are using public issue trackers and public discussion alias on projects. More people from the community are commenting and participating in the JSRs. The process of releasing final and maintenance releases is more agile," she commented.

She explained the different options for developers' participation in the JCP. Java user groups may become JCP members at no charge and contribute as a group. Individuals and user groups can contribute to the community initiative Adopt-A-JSR. Developers can give feedback on the transparency of a JSR process. Individuals, corporations and non-profit organizations (JUGs for example) can join the JCP. They then can comment on specs, join an expert group and become a spec lead





Information about the JCP program is available at jcp.org. Watch the recent presentation about Adopt-a-JSR with Martin Verburg and Java EE 7 JSR projects with Arun Gupta

OpenJDK, Adopt-A-JSR and Adopt OpenJDK Projects!

In two interviews, Martijn Verburg, leaders of the London Java user group and Cecilia Borg, Project Manager at Oracle explain the OpenJDK and two community projects Adopt-a-JSR and Adopt OpenJDK.  

"The Java Platform is huge and, to a lot of people, it is too big" explained Cecilia. "OpenJDK is divided into 22 different groups and 40 different projects to make it easy to participate." She recommends starting small by "subscribing to one of the mailing lists at openjdk.java.net" and contributing small bug fixes, for example.  It is important that contributors learn as much as possible and pick a project that feels right for them.


"The idea of Adopt-a-JSR is to have ordinary Java developers get involved with the creation of standards" indicates Martijn.  "Adopt-a-JSR is about Java EE and ME standards."  "The work on the Java language and the JVM is done as part of OpenJDK and Adopt OpenJDK projects," Verburg continues. He outlines how to start on those projects. Contributors can be individuals but also JUG leaders, who organize coding events to work on Java standards.

JavaFX and Java EE with Johan Vos!

Johan Vos is the co-founder and CTO of LodgOn, a company focused on “Java software for enabling communities.” In an interview, he shares his experience creating applications with JavaFX for the front-end and Java EE in the back-end. For one of clients, he created a badge-based rewarding system, which tracks user participation in social media and at events.

He sees a wealth of opportunities with JavaFX as client development platform and with Java EE as a back-end.  The challenge lies in “how you can connect the back-end servers with small devices like tablets, phones and embedded devices.” The opportunity is that “they have one thing in common which is Java”

A member of the GlassFish community, he considers JAX-RS 2.0 as an essential technology and standard. “REST interfaces and the JAX-RS API provide a standard that allows back-end applications to connect with any front-end clients”. He created the open-source project DataFX, “a JavaFX client that connects to any REST based back-end” and the open-source framework DaliCore that manages social media resources in Java EE applications.

Spotlight on JavaFX

In three interviews, veteran JavaFX developers Jim Weaver, Gerritt Grunwald, Pär Sikö and Martin Grunnarsson describe their JavaFX journey and their favorite JavaFX features.


Jim Weaver likes to call himself a “Java Technology Activist”. His three top JavaFX 2.2 features are deployment on Linux, Mac OS, Windows and ARM devices, Web View control and native installer running on user’s machine. He is also the editor of the JavaFXcommunity.com. This website “aggregates and provides a common place where JavaFX developers can find resources (downloads, APIs and real world examples) and a blog and twitter feeds.”


Gerritt Grunwald is a software engineer, working on interfaces and UI controls at Canoon Engineering AG. “I use 100% JavaFX today” and “I try to evangelize everybody to use JavaFX”. Gerritt sees great opportunities for JavaFX on embedded devices such as displays at airports or train stations. He presented a demo on how to create JavaFX controls on a BeagleBoard.


Martin Gunnarsson is a designer and front-end developer at Epsilon and Pär Sikö is a Java front-end developer at Jayway. Both JavaFX developers, they are convinced that “we have a very powerful WebView in JavaFX 2”. Their presentation was about how to bring web content into a JavaFX application and how to set up two-way communications between the Java and JavaScript code running in WebView. Their presentation called JavaFX Mashups is available online on JavaOne website.

Call for Papers for both Devoxx UK and France now open!

The two conferences are taking place the last week of March 2013 with London on March 26th and 27 and Paris on March 28th and 29th. Oracle fully supports "Devoxx UK" and "Devoxx France" as a European Platinum Partner. Submit proposals and participate in both conferences since they are a two-hour train ride away from one another.

The Devoxx conferences are designed “for developers by developers.” The conference committees are looking for speakers who are passionate developers unafraid to share their knowledge of Java, mobile, web and beyond. The sessions are about frameworks, tools and development with in-depth conference sessions, short practical quickies, and bird-of-a-feather discussions. Those different formats allow speakers to choose the best way to present their topics and can be mentioned during the submission process

Devoxx has proven its success under Stephan Janssen, organizer of Devoxx in Belgium for the past 11 years. Devoxx has been the biggest Java conference in Europe for many years. To organize those local conferences, Stephan has enrolled the top community leaders in the UK and France. Ben Evans and Martijn Verberg are the leaders of London Java User Group (JUG) and are also known internationally for starting the Adopt-a-JSR program. Antonio Goncalves is the leader of the Paris JUG. He organized last year’s Devoxx France, which was a big success with twice the size first expected.

The organizers made sure to add the local character to the conferences. "The community energy has to feel right," said Ben Evans and for that he picked an "old Victoria hall" for the venue. Those leaders are part of very dynamic Java communities in France and in the UK. France has 22 JUGs; the Paris JUG alone has 2,000 members. The UK has over 50,000 developers working in London and its surroundings; a lot of them are Java developers working in the financial industry. The conference fee is kept as low as possible to encourage those developers to attend. Devoxx promises to be crowded and sold out in advance. Make sure to submit your talks to both Devoxx UK and France before January 31st, 2013.

Devoxx!!

 Announcing Devoxx London! Taking place on  March 26th and 27th, 2013 right before Devoxx  France on March 28th and 29th, this will be the first  edition of Devoxx UK!. The call for papers begins  on December 1st for Devoxx in London and Paris.  Speakers will be able to present at the two  conferences in the same week. Oracle committed  to fully sponsor the three Devoxx conferences in  2013 with a platinum sponsorship. Over 5,000 developers are expected to attend those conferences.

Five dancing NAO robots welcomed attendees at the keynote. Stephan Janssen offers the JUGs to replicate Devoxx4Kids workshops using his content and web infrastructure.  He recommended organizing kid events because “the workshops were really fun and such rewarding experience.” Stephan also announced the redesign of Parleys with Html 5 and GlassFish. Friendlier to speakers, they will be able to post their slides online before their talks and then sync the talk's sound track with the slides.

Nandini Ramani, VP of product development explained in her keynote address the growing role of Java from enterprise application development to cloud computing to embedded machine-to-machines systems. “Java continues to drive the applications and devices that enrich our interactivity with the world around us” she said.

The Java platform has expanded its reach with the OS X and Linux ARM support on Java SE and Java embedded with two new releases, Java SE embedded and Java Embedded Suite 7.0 middleware platformComing up next year is JDK 8, which will include Project Lambda, Project Nashorn and more. As part of that release, JavaFX will offer 3D and third-party component integration. At Devoxx, the slick and interactive schedules were designed with JavaFX. The earliest version of the Java EE 7 SDK is available for download and has WebSocket support, improved JSON support and more. 

Stephen Chin arrived on stage with his bike, ending his European NightHacking tour. Check the hacking sessions online here
