Betcha Thought We Couldn't Do It

CommunityOne packs up and heads East

The long, strange odyssey of CommunityOne is about to get a lot longer. Remember, this is the event with its beginnings in the free pre-JavaOne "NetBeans Day", which when co-located with similar free conferences for GlassFish and OpenSolaris eventually became a cohesive and notable conference in its own right. And as it grows into more than just a bonus day of JavaOne, perhaps it makes sense to decouple and take the show on the road.

So, CommunityOne has announced it's heading East, holding its first-ever U.S. East Coast conference in New York on March 18, 2009, in addition to its now-traditional spot in San Francisco on June 1, the day before JavaOne. A Call for Papers is now underway for both events, seeking session, panel, and lightning talk ideas by December 11:

In 2009, CommunityOne will focus on the free and open platforms, tools and services that can be found powering the Internet, running enterprises, and enabling high-performance computing. We're open to all your ideas but are specifically looking for sessions on cloud computing and virtualization, dynamic languages and scripting (PHP, Ajax, Python, Ruby, JavaScript), databases (MySQL, postgreSQL), web and application servers (GlassFish, Apache), operating systems (OpenSolaris, Linux), mobile development (Java ME, Android, Symbian), and tools (NetBeans, Eclipse, Sun Studio).

It's also noteworthy that an event that was originally based around Sun's open-source projects is now open to all comers. Look at that CFP again: it's not just NetBeans, but also Eclipse. Not just GlassFish, but also Apache. Not just Java ME but Android and Symbian. Obviously, they're pretty serious about the "community" part of "CommunityOne".

Also in Java Today, the Planetarium passes along word that JavaFX 1.0 is set for a December 2 release. In anticipation of the release, InfoQ is offering a Java FX Technology Preview, based around an interview with JavaFX developer (and blogger) Joshua Marinacci. "Pitched into the Rich Internet Application space as a competitor to Adobe's Flex and Microsoft's Silverlight, Sun's JavaFX is one part of Sun's strategy for addressing these issues for Java developers. JavaFX aims provide a new foundation platform for building Rich Internet Applications across desktop, internet and mobile devices."

"Sun Microsystems and the Project GlassFish community have announced the release of GlassFish v3 Prelude, a modular, lightweight Web 2.0 development and deployment platform. The announcement underscores the momentum of the GlassFish v2 application server, which notched eight million downloads and over 200,000 product registrations in the previous twelve months." The SDN article GlassFish v3 Prelude Previews New Features summarizes the features in the GlassFish v3 Prelude application server and provides links to more information and downloads.

In today's Weblogs, Doris Chen discusses her recent presentation on Building Rich Web Applications using jMaki Framework. "I presented "Building Rich Web applications using jMaki" session this weekend at the Silicon Valley Code Camp at Foothill College. Many of the attendees asked for the presentation so I have posted my presentation here for your reference."

In Maven Test Coverage : Cobertura and Surefire working, Sebastien Dionne shows "how to enable Cobertura Test Coverage in Maven."

Finally, David Herron considers the importance of individual candidates in The upcoming JCP Java ME Executive Committee Election. "Just in case you're not all election'd out, and just in case the recent election in the U.S. gave you some hope that things can change through elections, here's an opportunity to affect the direction of Java ME."

In today's Forums, rlopes offers strategies for adapting to different displays in
Re: LWUIT and Diffrent phone Screen Size. "LWUIT aims to create only one version of the application that adapts itself to the device, but it doesn't do all by itself, the code you develop have to follow that approach too. You can use the default system fonts with relative sizes (small, medium, large) that are set by the phone manufacturer to be the best for that screen dimensions & dpi. If you really want to use custom fonts you can include several sizes and at startup choose and set the best for the device using the one that is closer to the system font size for that device."

Stephan Bardubitzki is looking for advice with
Signing LWUIT based Apps. "Nearing the completion of a network intensive app based on LWUIT I'm wondering whether there is any experience with code signing for LWUIT apps yet. I just remember a blog from Terrence Barr, I believe from Sept. 2007, where he mentioned developer friendly changes to the Java Verified Program. While one can still find links to his blog on Google , the blog itself has vanished. That makes me believe there will nothing change to this program anytime soon. So, what will be the best way to go? As far as I know VeriSign certificates are not accepted by most North American carriers, but actually in Europe and Asia."

michael_heinrichs considers JavaFX asynchronicity in the followup Re: Loading Image.
"The Image class is able to load its content in the background. It requires a URL to access the resource though, so I don't know, if this works in your case. Another option might be to extend AbstractAsyncOperation, but that is clearly a more advanced topic. JavaFX is a single-threaded language and you shouldn't create any new threads yourself."
