In my last post, I briefly introduced Rickard

As I was following Jfocus 2011 on Twitter, I was surprised to see that two new Java Champions were recognized at the conference. But when I realized that the new champions, Rickard Öberg and Jonas Bonér, both hail from Sweden, it made much more sense that the announcements happened at Jfokus.

In today's post, I look at some of Rickard's accomplishments, and his goals for the future. In my next post, I'll do the same for Jonas.

Rickard Öberg has had a long and successful career in Java technologies. He is currently most actively working on Qi4j which, briefly described, is "a framework for domain centric application development, including evolved concepts from AOP, DI and DDD." In the past, Rickard made important contributions to the XDoclet, WebWork, and JBoss open source projects.

When you look a bit more into Qi4j, you realize that Rickard is a visionary, as well as being a highly accomplished Java developer and architect. The Qi4j site outlines some of the problems that are inherent in Object Oriented Programming. A possible solution? Composite Oriented Programming (COP), which is a key underlying force that is currently being implemented in Qi4j. Among the principles of COP:

  • Behavior depends on Context
  • Decoupling is a virtue
  • Business Rules matter more
  • Classes are dead, long liveinterfaces

Reactingto being named a Java Champion, Rickard reflected both modesty and a vibrant team spirit:

It is a humbling feeling to be in the company of giants, and I hope to do justice to it in the future. I wish to thank the Java Champions committee for their work, and also everyone I have worked with over the years on different OpenSource Java projects. It is never a one-man-show and it is the community help and feedback that has helped me do all the nifty tools and frameworks.

With that kind of attitude and vision emanating from our Java Champions, I think we can all feel proud of our own efforts, and also more confident that Java and the JVM will indeed enjoy a long, productive future.

http://profile.ak.fbcdn.net/hprofile-ak-snc4/71139_103887892987741_4074044_n.jpgI came across the Morocco Java User Group when their Facebook page showed up in a Google Alerts search I have set up. The Group was founded by Badr Elhouari, Faissal Boutaounte, and Ayoub El Abbassi.

The JUG describes itself as follows:

The Morocco Java User Group MoroccoJUG aims to provide a platform for all Java enthusiasts to network, exchange ideas, share knowledge and help each other in order to strengthen the Java community in Morocco. Our members come from Morocco's considerable high tech community and multiple universities. We encourage anybody from beginner to expert interested in Java and related technologies to join us.

The Morocco JUG's first Facebook post was by Badr Elhouardi on April 20, 2010. It looks like the JUG was probably formed around that time. Their Facebook events calendar lists the Morocco Java User Group First event has having occurred on May 20, 2010.

JUGs on Facebook

Facebook is clearly becoming an important element of global social and business infrastructure. What's happening with Facebook reminds me a bit of America Online / AOL 10-15 years ago. Back then, company advertisements (at least in the United States) would tell the audience to visit them at America Online using their "keyword". Now, it's starting to seem like it's critical for companies to have a Facebook page, not just their own web site. Even Google seems a bit threatened, based on items I've recently seen in the business press.

Anyway, back to JUGs: a Facebook search for "Java User Group" turns up page after page after page of results. Facebook is clearly a platform that Java User Groups find convenient for maintaining an online organizational presence. This is something I plan to look into more in the coming months.

Today I was browsing news related to Java User Groups -- something I like to do in part as a means of assessing the directions where the interest of the Java community is trending, at the developer level (rather than at the big public announcement level).

I'm sure there will be more than six JUG meetings in the next week, but the meetings listed below are the ones my news and blog search turned up first.

  • Feb 11-12, Javagruppen (Denmark): Java - a cloudy affair - Everybody are deploying in the cloud - or are they? And if they are, why do they do it? How do they do it? What are the advantages? Are they successful? And what can you - as a Java developer do to get your application in the cloud...
  • Feb 15, Lyon JUG: Soir

A plurality of voters in last week's java.net poll believe that increased involvement by Java User Groups will improve the JCP -- but, a closer look at the numbers suggests a fairly tepid degree of confidence that more JUG involvement can make a difference.

The poll was stimulated by the recent news that SouJava, the Brazilian JUG based in S

This week's new java.net poll was inspired by John Yeary's recent blog post "Dynamic Languages on the JVM... Growth or Demise". John begins his post by saying:

Like most of you I saw the TIOBE Index this week. Java still holds the top slot, but the press is grinding out our slow inevitable demise.

I looked at the TIOBE report myself a couple weeks ago, and noted with interest the trends among the top languages: a gradual decline in the Java, C, and C++ lines, with Python showing a rising trend.

http://www.tiobe.com/content/paperinfo/tpci/images/tpci_trends.png

One thing that comes to mind for me, though, is that the Y-axis in this plot is "Normalized fraction of total hits (%)". So, the plot is saying that out of all hits found in TIOBE's search, the percentages for Java, C, and C++ are slowly decreasing. But, the missing variable here is the total sample size. My guess is that, in the past 10 years, the total amount of global software development has increased immensely. If this is true, then a plot that showed the total amount of development in each language would likely show almost every language in the chart above to have a rising trend.

I'm pretty certain there's much more active Java development happening today globally than was the case 10 years ago. I mean, I'll be stunned if someone can prove to me that that's not the case. So, if that's true, what does it mean to say Java, and (getting back to John Yeary's discussion) dynamic languages in general, are in decline?

Well, I don't vote in java.net polls, and I'm not trying to influence you either. I just found both the TIOBE Index and John's post quite interesting. So, I thought I'd talk about the genesis of this new poll.

Anyway, the specific question our new java.net poll asks is: Are dynamic languages (Java, Ruby, Python, Scala, etc.) in decline or on the rise? What's your view? Voting will be open for the next week.

In the Northern Hemisphere's mid and northerly latitudes, for some of us it's been a record-setting winter (most snow ever recorded in a single month, where I live, in Connecticut, US). So, what would you say if you were invited to take a nice cruise across the icy Baltic Sea, at night, a couple weeks from now?

It turns out that if you live in Finland, and you're planning to attend Jfokus 2011 (14-16 February), you've got an invite to do just that! Mattias Karlsson pointed out this opportunity to me. I won't be attending Jfokus myself, but if you're going to be travelling to Jfokus from Finland, the Vaadin team invites you to voyage with them from Turku, Finland to Stockholm, Sweden, on the evening of February 14 (returning on the 16th).

 

It's not going to be just a party for shivering and hoping some flashes and wandering ribbons of Aurora Borealis come down and warm you up, either. About 35 developers from the Vaadin team will be on the cruise, and they've got a stimulating evening of Java-related activity planned. There will be more than three hours of presentations and networking as the cruise proceeds. The presenters include Arun Gupta, who will be speaking about "OSGi and Java EE hybrid applications using GlassFish"; David Chandler, presenting "Inside Google Web Toolkit"; and Vaadin VP of R&D Artur Signell, who will talk about "Recent Development and Roadmap for Vaadin".

If you'd like to attend the cruise, you can register at the Jfokus 2011 with Vaadin meetup page.

I wish I could attend Jfokus, and cruise the Baltic in mid-winter as well. Instead, I'll have to stay home and keep chipping away at the icicles beneath the ice dams that have formed on our roof this winter :(

Dustin Marx discusses some current Java News: Java Hanging and Java Desktop Popularity -

Rick Regan posted Java Hangs When Converting 2.2250738585072012e-308 to look at an issue which causes the javac compiler and java launcher both to hang. His post is based on Konstantin Prei

A plurality of developers who voted in last week's java.net poll consider Java on the desktop to be the area that most desperately needs attention in 2011. A total of 611 votes were cast, and the poll inspired a discussion that included 11 posted comments.

The exact poll question and results were:

Which area of Java/JVM technology most desperately needs serious attention in 2011?

  • 7% (44 votes) - Java EE
  • 25% (155 votes) - JDK (Java 7, Java 8)
  • 31% (192 votes) - Java on the desktop
  • 16% (100 votes) - Java on mobile platforms
  • 5% (29 votes) - Java Web Services
  • 8% (48 votes) - New JVM languages
  • 2% (13 votes) - Other
  • 5% (30 votes) - I don't know

The first thing that stands out for me is: the area that received the most votes is an area that isn't receiving many headlines lately. What is the plan for moving Java forward with respect to desktop applications? Is there one?

Of course, the concept of "the desktop" is a moving target -- it changes as hardware and new devices are developed. What's the desktop today? A screen on a desktop or laptop? An iPad? A mobile phone? Is there really a distinction between the desktop and mobile devices? Some people think not; others strongly disagree.

jdevp2 commented:

If we add Java desktop and mobile , it's 47% as of now so people do care and like client Java.

And osbald wondered

Why have separate options for Java desktop and Java mobile? I thought the whole point of the new JavaFX effort was to address all the screens of your life. I don't want two unrelated UI APIs to learn & maintain and lets face it theres little chance of reviving Swing anymore as was made abundantly clear at Javaone - thanks Amy.

Some people were surprised by the number of votes "Java on the desktop" received. spullara commented:

I'm very surprised at the number of votes for "Java on the desktop". Why do people care about this?

sproketboy was both surprised and pleased:

Wow I was not expecting so many votes for Desktop Java. Makes me happy. I'd love to see improvements in this area. Like Java3d support.

aleixmr and steven_reynolds talked about their companies, products, and the problems they face going forward, in the absence of a continued focus and development of Java's capabilities on desktop platforms. Here'saleixmr's situation:

we develop business aplications for our customers, orders, stock control etc, for us is a MUST having a ui toolkit for the desktop. For us is a pain developing such an aplication with web tecnologies, we did via swing applets and hessian protocol and I must say it's amazing, fast and realiable. I woudldn't develop an application like this via AJAX/html/css in any way !! one must use technologies for their needs, not as a techy fashion, every tool is able to solve different problems, so living in a web 2.0 era does not mean we have to neglect desktop java apps !!

steven_reynolds works for www.int.com, which:

makes libraries and end user applications to draw complex petro-physical data. Java really works well, but could be so much better with just a little attention.

For example, some of our customers say that they won't touch Java because printing is broken. And it's true that printing has some issues that seem to bite really hard out of all proportion to their conceptual simplicity.

Another concern that we have is that the Oracle Engineering team seems to be saying that Graphics2D drawing is dead going forward, and that the scene graph technology will replace it. That would be a huge hit for us, and we'd like to argue against. In particular, we have displays with huge numbers of objects (think Seismic data sets with 500 GByte of data being drawn on the screen). Simply thinking that we can construct a scene graph that has all the objects instanciated is just not going to work for our use cases. Our experience is that immediate mode graphics (draw and forget) has some extremely important scaling advantages.

This brings me back to jdevp2, who commented:

I'm just curious if the result of this poll will be sent to Oracle. If not, the poll doesn't serve too much purpose.

The results of this poll can be sent to some people at Oracle. But much more is needed. I believe Oracle will listen to the argument that failing to attend to the needs of Java software vendors for whom desktop applications are a key component of their products is a serious problem.

The results of this poll, and especially the comments, are a sign that an almost exclusive focus on moving only Java EE and the JDK forward will cause considerable damage for broad segments Java community in the future. If Java on the desktop ceases to be a viable option for those whose products depend on it, Java itself will ultimately suffer the consequences as those vendors move to other platforms.
