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.

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.

We build too many walls and not enough bridges.

Introduction
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...
In this post I will share my recent findings about Container Dependency Injection in Java EE 6, in particular how to decouple the processing threads of event producers and event consumers.
Java EE 6 introduces a very nice dependency injection framework (CDI) that has superb support for the Observer pattern in the form of event broadcasting.
An Event in CDI is just a regular POJO:
public...
Programming
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!
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.
Still hesitating to join JCertif 2011 ? See the past event : JCertif 2010 and this blog post
Sometimes it makes sense to wrap a single code line into a class. An example is implementing the Range pattern.
A lot of applications these days title themselves RESTful. But how much REST is needed to be RESTful?
Accessibility
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.
Extreme Programming
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.
SwingWorker
Swing provides SwingWorker to execute tasks off the...
GUI
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.

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...

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;...
