Day CQ is a very popular enterprise CMS (Content Management System) suite from Adobe. Although most of the time the development on Day CQ is related to CMS and most of the development can be mapped to a proper CMS system, there are times when you would need to develop some logic in your application, or need to develop some feature that may not be available readily within Day CQ. In these cases, you may need to write some application code.
Day CQ is a Java based software, and Java is the most popular way to develop custom features and application logic. To be specific, Day CQ is largely built using OSGi - a technology that enables you to develop truly modular applications. Developing any custom Java application modules also needs to be built on OSGi.
I have noticed that developing OSGi modules is often a pain for a CMS developer, largely because of the lack of full development support (or call it a buggy development support) from the CRXDE (The bundled Eclipse based IDE), which makes OSGi module development to take long time and painful. This post intends to give more insights to a CQ developer on OSGi, and also to do faster development of OSGi modules with OSGi.
