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...

What it means to speak German fluently and to be able of C++
Several years ago one of our key coders moved from the south of Germany (where our HQ is located at the Black Forest) to the cold and rainy north, so we had to to find a suitable substitute. After screening lots of applications, we picked few to invite for an interview. It declared the candidate's ability to speak German and C++. So she...

Over the years, I've lived a double life. On one side, I've been a member of many "pure architecture" teams and forums. We couldn't see code with a pair of binoculars. On the other side, I've been knee-deep in the code trenches where emergent architecture changed and morphed daily. Architecture? What Architecture? All we had was code. That was...

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...

In the last installment of my post, I briefly described how to do Test Driven Development (TDD) in JavaFX using Model-View-Presenter (MVP) pattern. In this installment, I illustrate this particular piece in detail and provide working code samples. You can download the code here (Caution: 6.7 MB download).
The download is a zip file containing all 4 Netbeans projects. The code is tested with...

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;...

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:
