Java ME MIDP 3.0 in hand


Java ME MIDP 3.0 shipped recently, and the Janitor has already one of the developer phones in his hand as he writes (no jokes about one handed-typing please), complete with battery, clock and Twitter MIDlets and more. No big deal, but its the MIDlet environment that's really changed.

These MIDlets, which can now run concurrently, in the background, can start when the phone boots, can run as the idle screen, and can talk to each other thanks to the new inter-MIDlet communication mechanism, share libraries and respond to a bunch of phone events. And there's a raft of graphically related improvements to jazz up the look, especially on larger screens.

Devoxx 09: Day 2 Fun


It was a morning of keynotes examining the workings of technology professional, and a contrast of preaching styles.

Ivar Jacobson's Lutheran delivery allowed the audience to share in the nordic dispair of a participating in an industry in still seeking a single development methodology, before raising the collective spirit with a gospel of a universal one to be resurrected from the common elements of all the ones developed to-date. But it was hard for the Janitor's mundane mind to see if there was anything left in this intersection-of-methodologies except for good old fashioned common sense. And will probably Bourne in shell for saying so.

Next up was the evangleical Bob Martin whose exhortive style raised a lot of chuckles, mining such rich seams as: Developer versus Manager, and Project Trainwrecks We've All Survived. At times seeming like he might speak in tongues, the Janitor thought he was, unfortunately, glossolalia-ing over some nice practical advice about how to be more of a professional that produces write well-crafted code in which QA will find no fault.

And the day continued a stylistic Tower of Babel, with an last minute standin presenter of an excellent talk on Java classloaders having the nerves of steel to allow the audience to debug and fix his demo that had gone wrong; Stephen Chin's engaging JavaFX talk on the many excellent components in JFXtras (like the JavaFX table which performed beautifully with 16 million items), and FEST saw him running up and down the stairs asking questions and handing out t-shirts.

The stylistic nightmare that was four geeks in hats dancing to Rick Astley meant you were at the start of the live recording of the JavaPosse. There were predictably big cheers for Scala, Java EE 6's imminent (December 10th) release, mostly cheers for closures, and lots of other fun which you can catch up to when they edit the bad words out and publish it, if you weren't there.

Stephan Janssen really puts on a great show at Devoxx.

Devoxx 09: JDK 7, Java EE 6, JavaFX, Java Store and more


The Janitor is here at Devoxx, just down the road from Neelie Kroes !

 Her influence was on show at the Oracle keynote, which began with a legal disclaimer saying something about forward looking statements about products not being indicative of anything. One has to be sympathetic as the commission's wheels grind on, but it was a bit like hearing that the tenor has a sore throat before the opera starts. Happily, Roberto and Ludo were more melodious, announcing the imminent December 10th release date for Java EE 6 and Glassfish v3 and a demo of deploy-on-save in Eclipse (it could equally have been in NetBeans), re-deploying deployment descriptor-free servlets and EJBs to Glassfish v3 in about a second. Adobe gave an engaging keynote, and although the Janitor didn't love the smell of all the multistep automagical conversion to massage an app developed in the flash tool into something allowed to run on the iPhone (pretty sure Apple doesn't either), the image-to-widget tool in Adobe Catalyst demoed very well. Something to think about for the JavaFX Production Suite.

Next up the Janitor sat in on Mark Reinhold's session on JDK 7. There was a progress update on the projects you already know about, some of the Project Coin code snippets provoking murmurs of appreciation and the odd ripple of applause, as did Mark's proposal to add simplified closures proposal to JDK 7. Less good news on the schedule, but as Roberto is finding for Java EE 6, sometimes the wait can be satisfying.

After lunch, the voices became hushed and the big room where James was about to speak suddenly filled up. James talked about the JavaStore, which is in live beta, as well as a new set of cash registers. While you can still only purchase apps from the store in the US (until the legal team works through the retailing laws of every other country), you can submit apps today if you are in US, UK, Australia, India, China, Sweden, Brazil or Russia, with Belgium, Canada, Israel, Germany, Italy, France, Spain coming soon.

Richard and Jasper and Tor's session on JavaFX focused on the upcoming features in JavaFX 1.3 and on the authoring tool. Covering tasks, the new UI controls (like tree, menus, popups, tooltips, scrollviews etc), new region architecture for expanded CSS styling and super fast rendering, it looks like a tasty package in the works, and the authoring tool (last seen at JavaOne) was looking better than ever. Can't wait to get it out the door.

And for a while today #devoxx was trending on Twitter. Right now beer and frites are trending high. More tomorrow.

JavaFX: Really Challenging


Have you see the monthly challenges over at JFXStudio ?

All the entries have to have less than 30 lines or 3000 charcters of code. Last month the theme was Time, this month its the number 5. Numerologically speaking, the number 5 goes hand in hand with sociability, and a tendency to excess. Guess which member of the JavaFX team picked that one ?


And ProJavaFX co-author Jim Weaver has been running a JavaFX challenge of his own.

Java Store in final stages before open


The Java Store team here at Sun is in the final stage of readying things to fling open the doors to shoppers in the next week or so !

This means one more tweak of the store front: just like in a physical store, polishing signage, perfecting the display areas and checkouts: in this case making the final UI changes to the all-JavaFX desktop app that showcases all the Java and JavaFX applications in stock and allows purchase and installation.

And it means final verification of the apps that will be on the shelves of the store on the day it opens - approaching 50 already, as participants in the beta program will already know - with more applications, ranging from free to paid, to come. All coming in at the back of the store, the Java Warehouse, which has been pretty busy of late.

So if you have a Java or JavaFX app that's looking for an audience (like, perhaps the 60-70m that download the JRE each month...), you should stay tuned to the Planetarium. Much more in the coming weeks !

Launch parties for Java ME SDK for Mac and NetBeans 6.8 ?


Last week was a pretty busy one, with the release of Java ME SDK for Mac (early access), and the NetBeans 6.8 beta.

The Java ME SDK is the all-in-one phone to Blu-Ray app development kit, and the news is that its now available on the Mac platform too. Ready for the final NetBeans 6.8 release on December 1st, whose beta has already had a bunch of promising reviews for the new features, like zapping up the JavaFX code editing  and hinting niceties that Tor has often mentioned.

It's strange no-one suggested doing home launch parties for them. They can be such fun !

How would you rate JavaFX ?


Don't bottle up any unexpressed opinions about JavaFX, take the survey.

Mixed in with the usual snoozeville multichoice questions about the kind of project you work on, you get to rate the current feature set and rank the importance of new features the team's working on: tooling, more controls, performance.

When was the last time you did anything anonymous on the internet so quick ?

JVM Language Summit inspiration


It's hard to believe that the JVM Language Summit is only a year old, and the recent second iteration appears to have been a great success.

Hopefully soon you'll be able to watch the talks online, like last year's, but in the meantime all the talk materials are online, and there are some home video style vignettes here. For a concise written summary, take a look at these short summaries of day one, day two, and day three. All the LOLs and OMGs are archived here. Organizer and JSR 292 lead John Rose was inspired by the Greats, even as sartorial inspiration was reportedly in shorter supply.

As you will hear on the Java Posse, language success comes with great responsibility: Noop take heed. This new language (No-awp) for the JVM (or the idea of one) was introduced; the dust is still settling as to whether this year's Fan is going to storm the developer world, or just its own coffee cup.

New JavaFX User Group


Java User Groups have a long history. As you can see, they have spread all over the world.

Some of them have turned into whole conferences !

And now there's a new (second, third ?)  JavaFX users group, just down the road from the Planetarium.

Selling applications


Since the announcement of the Java Store at the last JavaOne, the team has been busy. The warehouse is really taking shape now, and the store front smells of new paint with its final redesign (thanks for the comments). There's a rumor that the cash registers may arrive real soon. And best of all, the shelves are fast filling up with the kind of assortment of games, facebook and twittery map style apps you come to expect from an app store (whether people actually come or not).

Stores are all the rage, because you can find what they you want.

Rather than being told at a creepy party.

Java ME Watch


...Java ME too has plenty to say.

While some are worrying about which market segment Java ME will rule, the Opera Mini browser, the leading mobile browser, which runs on Java ME phones, shipped a new beta which is getting some great reviews. Like competitor BOLT, which also runs on Java ME phones, it does what seems to be impossible: faster browsing on small devices through cellular networks by using a compression server.

Developers looking into the Swing inspired LWUIT framework now have a book to help them out, while the LWUIT team is looking forward to what's to come in the next version. You can hear one company's experience with LWUIT on the latest Java Mobility podcast.

See more on LWUIT in this new series of short videos on a range of Java ME topics, with shorts on Java Device Test Framework, JSR 290, and  too.

JavaFX Watch....on TV


Continuing in yesterday's vein, there's as much to say about JavaFX.

No doubt you saw the first real step towards JavaFX in your living room, with the announcement from Amino Communications to put JavaFX TV in its range of futuristic egg-shaped TV set-top boxes.

There's also been much talk of the new features in JavaFX 1.2, with a typically thoughtful and useful look at the new layout containers from Swing veteran Amy Fowler (and another tutorial here), and a neat feed reader from Jim Weaver here, and a nice blog on the RSS reader capabilities in JavaFX now here.

Since the UK's Guardian newspaper opened up all its news content to developers, there's a new JavaFX tag cloud navigator, accompanied by an interesting writeup of the creator's experiences with JavaFX and comparisons with Flash.

The JavaFX team pushed out a minor 1.2.1 update of the SDK and runtime, containing a number of bug fixes, new samples and performance improvements. Performance continues to be a strong driver for the next release, as you can see from Really Hip Smart Dude Richard Bair's 100,000 node blog.

JDK Watch: Back to school


What with zipping all over the place to talk to folks about using JavaFX, and the quarterly JCP EC meeting, the Janitor has so much news saved up !

Things are never dull around the JDK, and in the back to school rush, there's been plenty going on. Sadly, the Swing Application Framework hasn't reached a point where its ready to be included in JDK 7, but most all of the other features are on track since milestone 4 was released. As you can see in the latest builds, the team continues to tweak the new garbage collector and Project Coin announced its additions to the Java language.

Tomorrow, its the start of the annual JVM language summit, with a great looking schedule lined up. It seems that there's another language other than Ruby and Python: Duby (ok, its a hybrid) that's now using invokedynamic to speed its execution.

There's also more signs of developers trying out JDK 7. The new Filesystem API designed in JSR 203 seems to be a major attraction, indeed, for some, enough in itself to justify an upgrade. And there are more signs that its going to be fast, especially when Jigsaw is included.

JavaFX Roundup


From this detailed article about the new mixin feature in the language that replaces the potentially slow multiple inheritence, to a episode three of a continuing series about a new MVC based framework for building form based applications in JavaFX, there's been lots to say about JavaFX in the last week or so.

A couple of new games zoomed into view. As have some deeper reviews of JavaFX technology from those who have actually rolled up their sleeves and used it. Leading perhaps, to a remarkably precient (yet incomplete!) prediction of what is to come in the next version.

See you at Devoxx 09 ?


The Devoxx conference is something of a shapeshifter. One of the 'european JavaOnes', it grew out of the Belgian JUG, has undergone a number of name changes, and now has shifted up a month, starting this year on November 16th instead of its early December slot.

One thing has remained consistent though: its a well-attended conference with a lot of up to date and high quality technical content.

For anyone interested in JDK 7, or JavaFX you should hop online and get planning: many of the Sun engineers involved in those projects are already signed up to speak.
