As we began our Java adventure at Amway Corp 10 years ago,
one of the most important tasks we had to do was to create our Object Model.
We had a variety of Java objects that we were planning to use in our application.
How were they going to be "wired" together inside of the application?
After 4 weeks of Object-Oriented, J2SE, J2EE training; we set out to define our Object Model.
This model was...
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.
Still hesitating to join JCertif 2011 ? See the past event : JCertif 2010 and this blog post
Last week's kickoff of FESI's research program went very well. There are a number of folks (>500) who are now following this blog on Java.net, and a number who have gotten involved. While we wait for more folks, we'll be researching new technologies, the first being NOSQL databases.
If the kind of topics we're research interests you, please feel free to join the project;...
If you know the enemy and know yourself, you need not fear the result of a hundred battles. If you know yourself but not the enemy, for every victory gained you will also suffer a defeat. If you know neither the enemy nor yourself, you will succumb in every battle.

Ladies and Gentlemen, Like you, I'm intimately convinced that a professional...
When we starting planning how we were going to use Java technology at Amway (10 years ago);
we realized we had many decisions to make about standards to adopt, practices to learn,
architectures to use, patterns to follow, etc.
Fortunately for us, there were many sources of information to help us figure all of this out.

Any intelligent fool can make things bigger, more complex, and more violentBut it takes a touch of genius and a lot of courage to move in the opposite direction.
Ladies and Gentlemen, beyond the fact that I'm going today to share with you, most of the things a developer should know when building a JAX-RS web service with Groovy, this blog post is first and foremost a...
We build too many walls and not enough bridges.
In my previous blog post, I have asked to many of you this question: "What JSF should become?". And since then, I was quite silent. The reason behind it, is that I was working to build a concrete implementation of this vision and today I'm glad to give you a concrete demonstration of it. So Ladies and Gentlemen, why...
You want JAXB to unmarshal singletons? You already spent lots of time coding rather complex workarounds applying XmlAdapters and afterUnmarshal callbacks? The solution is astonishingly simple!
Yesterday I've held another round of my DCI (Data, Context and Interaction) talk at JUG Lugano; they are available at Slideshare. The presentation has been updated since the one held in Genoa one month ago; I've still shown examples using the NetBeans Platform Lookup, but code sketches have been taken from an Android context, rather than Swing. I should be able to publish a detailed...
Complicated year for me and I've not blogged something with decent technical stuff for a while. This is the n+1 restart that I'm trying... let's see if I can resume with a constant flow of useful stuff.
The subjects of this post are two: first, a design topic (how to avoid anemic object when handling the processing of configurations) and second some extensions of JAXB to accomplish the...
In JUG-AFRICA we started an Open Source project to manage the BIG ANNUAL EVENTS for our JUGs. The first release will be available in the early second half of January.
The application will provide a lot of services via the REST Web services.
Proof that an Architecture of which no greater can be conceived, must include impementation.
In the previous installment of Effective Architecture, I covered TDD with Model-View-Presenter. However the code I presented had synchronous server calls. In JavaFX (like Swing), the UI code runs in the Event Dispatch Thread (EDT). It is unwise to block the EDT. Hence it is encouraged to execute all server calls on a separate thread.
Swing provides SwingWorker to execute tasks off the...

On April 28th, 2010, we will be kicking off the first phase of FESI's research. This where we set up the project, and start to get our hands dirty. Attached is the flyer we will use to promote FESI and what we're trying to accomplish. Hopefully it will help us get the word out to the local community.
Also as the kickoff, we'll be participating with a networking group that meets...
Sometimes it makes sense to wrap a single code line into a class. An example is implementing the Range pattern.
The www.abelski.com web site offers free (for personal and academic usage) courses about various topics in software development. The site focuses on Java technologies.
How to do Test Driven Development (TDD) with JavaFX using Model-View-Presenter pattern? In this installment of Effective JavaFX Architecture, I address this question with all the details and working code samples.
