OSGi DevCon 2013
There are a number component models available to OSGi developers; Declarative Services (DS), Blueprint (BP), Enterprise JavaBeans (EJB), Contexts and Dependency Injection (CDI). Some have their roots in Java EE, some in open source projects such as the Spring Framework, others are standards at the OSGi Alliance, and some have DNA from all three. As is often the case where there are options available, there's rarely a one-size-fits-all. The 'right' choice may depend on the type of project you're working on, the existing assets, tools and skills at your disposal, and the runtime you're looking to deploy to. This talk will provide a brief overview of the four component models listed, describe their scope of capabilities, standards coverage, tools support, and available implementations in an efforts to help OSGi users find a path to a component model best suited to their particular task.
