Java User Groups (JUGs) are volunteer organizations that strive to distribute Java-related knowledge around the world. They provide a meeting place for Java users to get information, share resources and solutions, increase networking, expand Java Technology expertise, and above all, drink beer, eat pizza and have fun.

The JUG Community is the meeting point for JUGs, helping promote the expansion of the worldwide Java Community. JUG leaders & members, from experts to Java newbies can share information about creating, joining and running a JUG. And because of a strong partnership between this JUGs Community and Sun Microsystems Developer Outreach, you'll also have direct access to Sun's speakers, latest information, giveaways and program personnel.

So, whether you're already part of a JUG, looking to join one, or if you're interested in creating your own local group, you've come to the right place! Welcome to the Java User Groups Community!

Take a look at the JUGs Community Objectives, to learn how your JUG can benefit from participation in this community!

Recent discussion on the JUG Leader's mailing list is about a new version of Jim Weaver's Classic JUG Prize wheel using JavaFX. Java Champion Stephen Chin showed off the new and improved version at Silicon Valley Code Camp Oct 4th, 2009.
"...By the way, for any JUG leaders or Champions interested in using the prize wheel, it does not require your event to be on meetup.com. You can simply paste in a list of names (one per line) into the manual entry box to populate the wheel..." -- Stephen Chin
"..Wow, it is really awesome.... Thanks for great tool. I was always missing it and using some random.orgwebsite or something else..." -- Grzegorz Duda (Polish Java Users Group)

Sun Java Evangelist, Sang Shin recently wrapped up a 5 day trip to the JRSL conference in Chile. JRSL09 is community organized conference by open source enthusiasts in South America. Countries (Argentina, Chile, and a few other countries except Brazil) take turns hosting the event. This year's event was attended by ~1100 people. Sang's talks: "Java SE 5, Java SE 6, JDK 7", 3-hour JavaFX workshop (2 hour lecture + 1-hour hands-on lab) [a couple folks currently using Flex, asked me if JavaFX supports "Flex remote object binding(?)" kind of capability. I told them JavaFX supports RESTful Web services API which should suffice for most remote communication needs]; Ruby/JRuby/Rails workshop. Sang, also attended a 2-day Mozilla conference. Highlights: Firefox now command 23% of the browser market world-wide; In some countries (some European countries), the market share are close to 50%; During the 9-month period, the Firefox usage went up from 5 million to 9 million in the South America region; Mozilla guys seem to be very confident that they will keep gain market share at the expense of IE; OpenVideo in HTML 5 will make flex/flash a dinosaur, eventually, but it will take a few years. Sang's trip was sponsored by: Exelsys, a ~50-person consulting company who specialize in Java EE-based financial apps for the Chilean banks...more info at javapassion.com ***Sang will next be speaking at DEVOXX.

Java Evangelist, Sang Shin recently wrapped up a recent trip to a Mexican University. He was invited by ITESM, Chihuahua campus to teach JavaFX programming to their 3rd/4th year Comp. Sci. students. The event is organized as a yearly "Invite the industry expert " program. Sang noted that Mexican students are quite familiar with Java programming language and NetBeans. Sang delivered content that was mostly based on: "JavaFX programming (with Passion!)" (which is free). Sang covered all 16 JavaFX topics during his 5-day stay. The course is half lecture and half lab and the students seemed to enjoyed the technology very much. Most of them will participate in Jim Weaver's JavaFX coding challenge. Some students were quite bright enough to ask these questions:
  • Does JavaFX support CSS3?
  • Is there graphical tool that lets a designer/developer to set the effects (instead of manually coding)?
  • When do we want to use "bind with inverse"?
  • How to convert Java ME apps to JavaFX apps?
Sang talked to many University professors during his trip. The professors indicated they teach java programming courses at (5) different levels, including one professor who was teaching a "NetBeans" course. Sang, asked him whether he meant "Java course using NetBeans" or "NetBeans" course. He said the latter. The focus of the course is to teach students how to use NetBeans IDE effectively.

Sun Microsystems Java Evangelist Doris Chen reports: "...The 4th Silicon Valley Code Camp took place at Foothill College (Los Altos, CA) on (Oct. 3-4). Over a thousand developers attended this event and 140+ sessions were presented. I presented "Developing Revolutionary Web Applications using Comet and Ajax Push [on Slide Share]". The session was extremely well attended (full house with around 80 people). The session was very demo intensive. I did 4 demos and showed a lot of code throughout the presentation. The session is well received as I got a lot of good feedback and questions during the session and afterward. One engineer from Yahoo Java EE group asked for more follow up as they are planning to use Comet for a future project.... Thanks again to Michael Van Riper and Kevin Nilson (Silicon Valley Web User Group) for inviting me back this year...." -- Doris.
Also, sessions by: Sun GlassFish Evangelist Arun Gupta [blog entry w/presentions here] and Java Champion Stephen Chin - "Getting started with JavaFX/WidgetFX + the New JUGPrize wheel. SVCODECAMP "presos" are up on slideshare.net.

The Java Users Group of the Federal District of Brazil in Brasilia – DFJUG (www.dfjug.org) was established in 1998 out of a need for qualified Java professionals. Today, with 46,983 members, DFJUG is considered one of the largest Java User groups in the world. It is DFJUG's educational focus which is the main driver that keeps this community together and growing --- Why?

Daniel deOliveira (currently working at the Brazilian Ministry of Planning) explains, that in Brazil, there is a shortage of IT professionals. There are currently 40,000 java-related jobs that are open and unfilled in Brazil. Furthermore, Brazil's formal educational sector (universities, colleges, technical and IT schools) has not been able to meet the demand. So, DFJUG began searching for answer(s) and asking questions like: Where does one find individuals that fit the IT developer profile? Where to find these “geniuses” that, without any formal or academical training, are capable of disassembling and reassembling a cell phone or even program these devices?

Recently, Sun's Scott McNeally was interviewed by businessweek.com “Next: An Internet Revolution in Higher Education”. There is a connection between this article and what groups like DFJUG have been doing with student developers. (i.e ...Web technology being used to shake-up education, the way it rocked newspapers and the music industry...). What was not mentioned in the article was Sun's contribution in founding/funding the Java Education and Development Initiative (JEDI) which is an open-source education curriculum at the University of the Philippines.

JEDI seemed like DFJUG's answer. So naturally, good community leaders tend to gravitate to each other, and the JEDI professors met Daniel as Java Champions at JavaOne in 2006, one thing led to another and JEDI-Brasil was created. Today, the program has (9) open source course modules focused on Java programming which is now serving over 39,000 students online. The initial training provides a foundation for future Java training and potential certification.

To see more about JEDI-Brasil check out DFJUG's online website, which serves as a online training platform for free video-based training modules (in Portuguese). Sun has donated a SunFire T2000 server in 2009 to help the JEDI-Brasil effort. Daniel can be reached via the website and will be coming to the U.S. in late 2009 to work on his doctoral thesis.

"...JUG Stockholm hosted a Java programing contest recently. 8 teams hacking for 3 hours building a virtual robot on a mission to find gold on new planet (a REST api). 120 people in the audience with pizza, beer and mingle betting on their favorite team. The winning team built a fully automatic robot in less then 3 hours and just leaned back an watched the others get run over....Total success and we even made it to the largest computer news paper in Sweden. Article here... " --- Mattias Karlsson JUG Leader

Sang reports: "....Dan Sline co-leader of the Houston Java Users Group, and, he is a co-organizer of this code-camp style event. Over 1600 folks registered for this event. Approx 1/2 attended throughout the day. --- I gave (3) talks:
  • "JavaFX II: Advanced features (pdf)" --- (One of the attendees had deep knowledge of JavaFX; he had a licensing question regarding the reuse of dtfx.js at his company)
  • Build truly async. Web apps using Comet (pdf forthcoming) --- (There was interest in using a combination of Comet and JavaFX/Javascript; an interesting combination to solve a problem. Some of the Microsoft guys aked if Commet was available in .NET; Yes, ASP.NET has its own Cometd implementation. Talk went pretty well + lots of interested in Comet)
  • JDK7 and Java EE6 (pdf) --- (Very Well Attended! Overall, people seemed to be quite excited about the Modularity feature)
Nonetheless, the conference seems to have some respect from developers due to its deep-down developer focus...". -- Thanks Sang

"....A sincere thank you to Sang Shin for coming out to this year’s HoustonTechfest (we had over 800 people in attendance). We wouldn’t have been as successful without him.....Thanks again Sang!!!... " --Dan Sline Houston JUG 9/29/09

[There was this] "...huge tension between those who advocated for the adoption of free software by Brazil and those who thought we should do the sameness of always, buying, paying for others inteligence[sic] and, thank God, prevailed in our country the issue and the decision of free software. We had to choose: or we were going to the kitchen to prepare this dish the way we wanted to eat, with the seasoning that we wanted, to give a Brazilian taste to our food, or we would eat what Microsoft wanted us to eat. Prevailed, simply, the idea of freedom...." -- President Luis Ignacio Lula da Silva of Brasil at FISL 10 2009 --- (english transcript of Lula's speech here)

This past week's poll suggests that Java User Groups have a substantial impact and play an important organizational role within the Java developer community. A total of 293 votes were cast in the poll. Here are the exact question and the results: Do you belong to a Java User Group?
  • 22% (65 votes) - Yes, and I actively participate
  • 26% (75 votes) - Yes
  • 5% (15 votes) - No, but I sometimes attend JUG-related events
  • 3% (10 votes) - No, but I follow JUG-related news
  • 12% (35 votes) - No, there is no local JUG where I live
  • 31% (90 votes) - No
  • 1% (3 votes) - Other
Among those who chose to vote in the non-scientific survey, 56% either belong to a Java User Group, attend JUG events, or follow JUG-related news. Among the people who stated they do not belong to a JUG, about a quarter have no local JUG they can participate in where they live. Almost a third of voters selected the "No" option, which implies that they could participate in a Java User Group, but currently choose not to do so. That's a fairly low fraction, in my view. The poll elicited four comments. rdelaplante and jwenting commented that the JUGs in their areas have too many commercial presentations by companies and vendors. rdelaplante said: I think my local JUG should be renamed to SUG (Spring Users Group) since we've recently had 3 presentations from SpringSource, and some of the other vendors that give us their sales pitch focus on Spring too like GigaSpaces. Why isn't Sun out here pitching GlassFish and Java EE 6? I guess it can be challenging for JUG leaders to find a constant stream of speakers, and companies like SpringSource are eager to take full advantage of the opportunity to give their sales pitches in every major city. jwenting commented: "From what I've seen around here the JUG(s???) seem mostly to exist for the purpose of companies presenting whitepapers and giving commercial presentations of products. Not very useful at all." To these comments, JUG co-leader fabriziogiudici responded: Co-leading a JUG and attending some meetings from others, I can say I've never seen any whitepaper, any commercial presentation or any speech by a big company representative - with the exception of some specific events (e.g. the IDE shootout or the Application Server shootout) where representative from the various producers were invited - in any case, the talks were exclusively technical. JUG Roma is the one capable in Italy to organize the largest single-day gatherings (1200+ attendants) and, again, no white papers or commercial stuff at all. In normal cases, speeches are mostly held by JUG member themselves and arguments decided by means of the mailing list - usually they are the guy's direct experience with a technology, which also gives good hints for a discussion. I wonder whether there are big differences in how JUGs are managed in various parts of the world. Meanwhile, ipsi finds "very little promotion of the local JUG": So, it seems like the size of the Java User Group matters a lot, along with the location; and probably there are also some differences in management. A big JUG where enough members live nearby probably has a much easier time with having technical presentations by the members themselves. Whereas, smaller JUGs, or JUGs in regions that are not all that metropolitan, will have fewer attendees at the JUG meetings. And, a smaller pool of active members translates into a smaller pool of potential presentations from the members themselves. So, in order to have something interesting and at least somewhat relevant, vendors are called upon. Surely some vendors are more adept at presenting a genuine technical talk, while others will present mostly their standard marketing spiel.:O'Reilly Media
