My name is Haim Michael, I am the General Manager for Zindell Technologies and I am an eternal student and a lecturer. I chose to develop the abelski web site for the benefit of all people world wide. I have started to develop it in November 2007 and I continuously update its courses and add new ones. All courses on this web site are available for free personal and academic usage.  The...

GUI

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? The history of JavaFX has been contentious since its beginning, when it was clear that FX was a new toolkit, even a new platform, while most people in the brave Swing community wanted a "Swing 2.0". Well, this is basically what...

The SwingLabs BOF had a good number of attendees (more than last year I believe).  Jan and I focused the update on SwingX, but did speak about JXLayer some. We also announced the release of version 1.6.2.  As promised, I have uploaded the presentation. All in all, I think it has been a very positive convention for SwingX (so far).  I spoke about SwingLabs/SwingX at the end of...

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...

On my wordpress blog, I've composed yet another digest of JavaOne highlights.

I am happy to announce the release of Apache Pivot 1.5! Apache Pivot (http://pivot.apache.org) is a platform for building rich Internet applications (RIAs) in Java. It combines the enhanced productivity and usability features of a modern RIA toolkit with the robustness of the industry-standard Java platform. Pivot 1.5 includes a number of improvements intended to help improve the overall...

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. Un-Scripting JavaFX Script The first version used a "scriptish" style, all code thrown in a single .fx file, only average effort in structure. Now I have three files: World....

JavaOne

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. JavaOne is the biggest and most important conference for the international Java Community to discuss the latest issues of the Java technology. Kai Reinhard and Florian Bachmann from the Micromata GmbH will present JAK on this occasion. JAK is...

Mobility

When the iPhone came to market, Sun Microsystems announced that there soon will be Java for the iPhone. They got stopped by Apple's licence terms, which ban both, interpreted languages and code written in other language than C, C++, Objective C and JavaScript. Lately I read in the news that Apple change the licence terms, and found a promising statement on Apple's web site, so now...

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? As a big enthusiast of both Jigsaw and Lambdas - and as a tech writer who just...

Programming

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 too fun to ignore: an interesting challenge in algorithms, and another opportunity to exercise JavaFX as any geometric problem surely deserves some GUI. (Don’t read this blog if you actually plan...

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. The really major feature of this release is for developers: debugging and profiling will now, well,...

Update (2012-09-24): Maven users, you can directly link this class (LGPL), as I have uploaded it into Maven Central. Simply add a dependency to: <dependency>    <groupId>eu.headcrashing.treasure-chest</groupId>    <artifactId>EnumerationsClass</artifactId>    <version>...

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...

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: <p>var bits = for (i in [1..64]) (0 as Long);</p> Problems: First, I need a loop - OK, a comprehension - to initialize the sequence. There is no syntax, no API helper or type constructor, that directly expresses "Long[] with N elements...

J2SE

CONTEXT I want to share a problem that we had in our project. We were doing a real-time "Profits and Loss" server (P&L). The server sends stock updates to all the users subscribed to the stocks, basically as Google Finance or Yahoo Finance. SIMPLE IMPLEMENTATION I will used a basic approach (no aggregation and no optimization) to explain the problem that we had with Serialization and...

Databases

In my opinion, SQL Anyhwere is the best RDBMS I can think of. I can remember when we started distributing it in Germany back in the early 1990ies, as one of the first early adopters in this country. Since then, we provided it to hundreds of enterprises, from single-person laptop-only ones to large ones spanning replicated installations crossing country borders. So call me biased in that...

Security

 In two previous entries I covered Introducing NIO.2 (JSR 203) Part 1: What are new features?  and Introducing NIO.2 (JSR 203) Part 2: The Basics  In this entry I will discuss Attributes introduced in NIO.2. Using attributes we can read platform specific attributes of an element in the file system. For example to hide a file system in DOS file system or to check the last access date of a file in...
