User Groups at JavaOne

User group leaders from around the world meet once a year at JavaOne. Each year, they organize the Forum meeting the Sunday before JavaOne. Speakers and topics are vetted by community. Anyone attending JavaOne whether they belong to a user group or not are invited to those sessions. Make sure you arrive on time for the Forum on Sunday. It starts at 8:00am at Moscone West. Among the topics this year are NetBeans community and tools, Java EE and Glassfish update, lightning talks about productivity, Java tools for Maven and Java EE, free Java tools and how to teach Java. And you don't want to miss James Gosling. He will present his latest work on the Raspberry Pi, Robots and Small Devices. If you have not registered already.

Register by tomorrow Friday August 1, 2014 and take advantage of the Early Bird rate. It is a US $400 saving on registration!

The six month old virtual Java user group (VJUG) has now 1,200 members. London Java Community leader and technical evangelist Simon Maple created this user group so Java Developers could connect virtually. The group organized 10 sessions, all available online: 
  • Design is a Process, not a Document by Trisha Gee
  • Drive by Contributions A GitHub session by Brent Beer and Matthew McCullough
  • Don't be that guy! Developer Security Awareness by Markus Eisele
  • Getting Started with Java EE 7 by Arun Gupta
  • How To Do Kick-Ass Software Development by Sven Peters
  • 55 New Features in Java SE 8 by Simon Ritter
  • Comparing JVM Web Frameworks by Matt Raible
  • WebSocket Applications using Java EE 7 by Arun Gupta
  • Project Lambda: Functional Prog. Constructs and Simpler Concurrency in Java SE by Simon Ritter
  • Java 8 Parallel Streams Workshop by Stuart Marks

The purpose of the group is to provide content to developers who cannot attend JUG meetings. It will never replace the experience of a face-to-face meetup.  Simon is looking for ideas to best help existing JUGs.

Gamification for User Groups

At the gamification session of the International Oracle User Group Community (IOUC), leaders discussed how to drive membership. Typically, they give away licenses, books and goodies to encourage attendance at monthly meetings. Others have used gamification to get their communities to brainstorm on mascot names, or post pictures and comments on social media. Hackathons also require the use of similar techniques to keep attendees motivated to create applications over several days. SouJava leader Bruno Souza successfully ran hackathons that combined brainstorming, team building, training, hacking sessions and prizes to keep participants engaged.

“Turn life into a game, drive engagement of audiences, make the experience more enjoyable and get users to come back ” are the key advantages of gamification according to user group leader Jim Bethancourt.

The forum platform Stack Overflow is a great example of running a thriving community of developers with its point systems. Contributors get rewarded with points for their useful entries and visitors easily find the most relevant and best-rated entries.

The ArabOUG has implemented a point system to keep its community active. The group gives out points to the members, who contribute applications, articles, and translations. It partnered with training organizations and other services to give its members free training and services in exchange for points. As a result, members don’t have to pay for services using online payments, which governments in many countries in North Africa and the Middle East don’t allow.

In an interview, ArabOUG leader Mohamed Chargui  explains in more detail his experience using gamification.

Java EE 7 Open and Transparent

In his blog titled "Transparency and Community Participation in Java EE 7", Java Evangelist Arun Gupta explains the "high level of transparency for all of the Java Specification Requests (JSRs) under the Java EE 7 umbrella" and the increase of up to 7.5x participation by Java developers from previous releases. 

Since October 2011, JCP 2.8 has set eight new transparency rules for all new projects. The rules require the disclosure of such information as Expert Group member information, technical discussions, public feedback, JSR schedule, RI and TCK processes, and public documentation. Arun shows how the transparency rules apply to the JSR 342 project. 

About 20 Java User Groups (JUGs) from around the world contributed to the fourteen Java EE 7 JSRs. In many cases, the JUGs involved contributed to several JSRs via the community run initiative Adopt-a-JSR.

Arun lists JUGs events, their presentations and the code they contributed as a results of those events. They are great examples for other JUGs to get involved. Java EE still has projects open and Individuals as well as JUGs can contribute in three steps: join a JUG, participate in Adopt-a-JSR, choose a Java EE 7 JSR.

Arun Gupta on Higher Productivity from Embracing HTML5 with Java EE 7

Oracle’s Java evangelist and noted Java EE expert, Arun Gupta, presented a session at the annual IOUC (International Oracle User Community) Summit, held January 14–16, 2013, at Oracle headquarters in Redwood Shores, California, where more than 100 top user group leaders from around the world gathered to share best practices, provide feedback, and receive updates from leading Oracle developers.

Gupta’s talk, titled "The Java EE 7 Platform: Higher Productivity and Embracing HTML5," presented a glimpse into the rich possibilities that will be available in Java EE 7 upon its release in the spring of 2013. He covered several major developments, including:

* Java API for RESTful Web Services 2.0
* Java Message Service 2.0
* Java API for JSON Processing 1.0
* Java API for WebSocket 1.0
* Bean Validation 1.1
* Batch Applications for the Java Platform 1.0
* Java Persistence API 2.1
* Servlet 3.1
* Concurrency Utilities for Java EE 1.0
* JavaServer Faces 2.2

Gupta focuses on ways in which Java EE 7 offers higher productivity; less boilerplate; richer functionality; more default options; and HTML5 support in the form of WebSocket and JSON. He also observed that the cloud is in need of more standards. From the article:

"There are not enough standards in the cloud with W3C and other standards bodies. More standards are needed so that we can define a Java API for the cloud. Premature standardization can also be a problem if not enough innovation has taken place. So what is the right thing for the platform? We have reached out to the community, the core group members, and the executive committee of the Java Community Process and have focused on providing higher productivity and on embracing the HTML5 platform more closely. We are going to use dependency injection a lot more, which will give developers the ability to write less boilerplate code and offer richer functionality such as batch applications and caching. Similarly, for HTML5, we are embracing WebSocket functionality and the ability to parse and generate a JSON structure. We are providing support for HTML5-friendly markup as part of JSF.”

Gupta summarized the strengths of the various JSRs and closed by encouraging developers to participate in Adopt-a-JSR, a project that enables them to, “pursue their interest in particular Java EE 7 JSRs and download code, play with it, report bugs, and offer feedback to Java EE 7 specification leads.”
