Increasing complexity in a software product, whether embedded, client or server, requires modular code, but also systems that are dynamically extensible. The OSGi framework aims to implement a complete and dynamic component model that is missing from the Java environment. In fact, Java language provides some mechanisms that allow us to create a component model, but they are still low-level solutions, resulting in the risk of introducing code errors as well as becoming an ad-hoc solution. OSGi solves many of the problems associated with poor Java support in modularity and dynamism through some key concepts:
- Automatic dependency management
- Definition of the module concept (bundle)
- Code life cycle management (dynamic configuration and distribution)
In summary, you can regard OSGi technology as follows:
- A dynamic system that allows you to install, start, stop, and...
