Google maps was a useful hit from the moment it went on line. Since then thousands of web pages have added map capability to their sites, courtesy of Google. Let me illustrate how you can add Google maps to your Java application. Background Google furnishes its maps via a simple REST request. Does this mean you need to add some fancy REST framework to your application? Not at all! Java provides...

It seems that when we develop a trait (that includes both abstract and concrete methods) in Scala and compile it, the outcome includes two jave byte code files. The first includes the definition of an interface with an identical name to the one we gave our trait. The abstract methods that interface includes are the same methods defined in our trait. The other file includes the definition of a...

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...

Education

I'll like to let you know the dates of JCertif 2011 the biggest Java Community Event in Africa. About 800+ attendees from many countries. We will be happy to have you as Speaker on Developer Tools, Java, Open Source, Mobile Apps...or Business solutions.

Often code has a bad smell, then it gets time to replace custom lines by common patterns. Sometimes it even makes sense to even replace a single line of code by a class just wrapping that single line (which actually increases code size), if that makes readers better understand what the code does. Unfortunately often such patterns are publicly known but do not exist as ready to...

Programming

Meanwhile I am looking back to more than 25 years of programming, and more than a decade I spent in a very sensible area where quality (in the sense of zero failures) plays a big role. So call me "sensible" for quality. For long years "we" (i. e. developers) had hard work to do using simple command lines tools like vi etc., but meanwhile there are great, even free,...

After more than a decade in the Java universe, today I had just enough of remembering where my executable JARs are located and typing all the lengthy path names, so I finally taught Windows to deal with Java archives just the same way as it deals with it's native executables EXE and CMD. The trick is so simple that I actually do not understand why the JRE installer isn't applying it automatically...

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,...

GUI

The question of how to combine Swing and Apache Pivot components comes up often enough that I thought I would write a quick blog entry about it. Pivot doesn't currently support embedded Swing components. However, it is possible to use Pivot components within an existing Swing application. The following demo shows a number of Pivot components hosted in a JInternalFrame; another internal frame...

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...

Swing

A decade from now 90% of people will use phones, slates, or netbooks as their primary computing device. This is a very exciting development in the software world and promises to reshape the way we make software (check out the great stuff our lead developer is doing in his day job at Palm), but Amino isn't for that world. Amino about that 10%: the content creators who need killer desktop apps, the...

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...
