What is Qi4j?

The short answer is that Qi4j is a framework for domain centric application development, including evolved concepts from AOP, DI and DDD.

Qi4j is an implementation of Composite Oriented Programming, using the standard Java 5 platform, without the use of any pre-processors or new language elements. Everything you know from Java 5 still applies and you can leverage both your experience and toolkits to become more productive with Composite Oriented Programming today.

As Rickard Öberg and Niclas Hedhman are the founders of the project. So we need pay attention on this project.
