Modularity is the art of breaking a large system into parts that are easier to understand than the ‘monolithic’ whole.
Failing to achieve the right degree of modularity may lead to development of code that is hard to reuse and to maintain, and when you are working in a team this has a bigger impact on the costs.
The complexity of dealing successfully with modularity is mostly addressed during design, when understanding and planning the dependencies and the behavior of a module, but a good application framework can influence positively toward the right direction by providing a natural environment where to apply good architecture modularity patterns. And OSGi, with its service oriented philosophy and the ecosystem of related tools, where the modules have clear boundaries which coincide with those of ‘Bundles’, it provides such inspiring environment.
During the talk we will illustrate a concrete example of an OSGi project, built with Maven and M2E and running into Apache Karaf. Rather than focusing on the details of technologies, we will put emphasis on the experience of Java modularity so to give a feel of how this platform can help, and allow you to evaluate if this platform can be helpful for your next project and ambitions.
