The biggest announcement - and the biggest surprise for many - of JavaOne 2010 was certainly Oracle's new plans for JavaFX 2.0... or, should we say, Swing 2.0?
SwingLabs BOF Presentation Slides
As it became almost a tradition we have rolled out next SwingX release just before the SwingLabs BOF at JavaOne last night.
You can get the release from our website, or directly from the java.net or also from the maven central repo. Please note that the artifactID has changed from swingx to swingx-core due to changes in the structure of the project.
Thanks a lot to all who contributed to...
With a renewed focus on the core JDK, JavaOne is looking up....
Announcing the release of Apache Pivot version 1.5.
I've finished the development of my Game of Life, with a couple final fixes and new features... including a solution to the bad performance reported before. Once again the work has uncovered some surprises; read on.
San Francisco/Kassel, September 2010. Micromata has been invited by Oracle to present a new Java interface for KML at this year's JavaOne in San Francisco.
Today I read that Apple finally allows interpreted code on the iPhone. When will Oracle deliver Java for iOS?
Mark Reinhold announced today that the JDK 7 / JavaSE 7 project has slipped once again: mid-2011 without Jigsaws and Lambdas, late 2012 for JavaSE 8 with those. The delay (or some other bad news like dropping features) was already expected by anyone who tracks the project. But really, how big and bad is this delay?

If you want to work for DropBox, they have an interesting programming test which solution must be submitted together with the CV. I’m not considering a position at DropBox, but their test was very fun to ignore: an interesting challenge in algorithms, and another opportunity to exercise JavaFX as any geometric problem surely deserves some GUI.
Now that JDK 6u21, JavaFX 1.3.1 and NetBeans 6.9.1 are all finally released, I'm back to checking the latest news and improvements in JavaFX. The official Release Notes points to the deployment improvements as the single new end-user feature, so I've checked the latest improvements in this area.
Iterating over an Enumeration with the for-each statement would be fine, but the JRE's default support is not very smart. So I wrote my own utility providing five times better speed, using virtually no heap space.
Here is a little code challenge !
I'm actually working on a text-mining/semantic web application focused (for the moment) on biomedical informations and developed in Java. We are using external tools for text-mining analysis and unfortunatly theses tools don't handle HTML pretty well ... If we send raw HTML to the text-mining service, he simply break. So we must convert HTML to plain-text before processing text, and because the tools return identified words by giving their positions, we must translate theses position (or indexes) to find corresponding word in the original HTML.
I created a simply implementation and posted it on gist.github.com ... can you make it better ?
I was doing some JavaFX hacking, and I had to create a sequence initially full of zeros. How can you do that? There's apparently only one way...
<a name="abstract">In the month of June 2009, I did an initial post in the openjdk.java.net-jdk7-dev<br /> mailing list with a request for what I feel are two very important changes<br /> required in the Java Platform.This resulted in a thread of discussions...
Java Serialization is commonly used everday since web 2.0, but sometime you can have problems. See a actual production problem with serialization that was fixed using the reset method.
Finally iAnywhere answered my prayers and implemented support for JDBC batch mode into their latest (and fastest) driver. But at surprisingly bad performance. Let's see why.
This entry discusses file permission and file attributes support in NIO.2 or JSR-203 which will be part of JDK 7. In this entry you can lean how to read the file attributes like creation date, size, and permissions like execute, read and write flags.
