OSGi for Application Developers



Neil Bartlett presents OSGi to Java developers: an introduction to OSGi – the standard module system for Java -, infrastructure projects using OSGi, the partial failure of OOP, the benefits of using COP – Component Oriented Programming – and how to implement components, including a demo.


Neil Bartlett is the author of "OSGi in Practice" and the tutorial series"Getting Started with OSGi." He is a developer, consultant, and trainer specializing ins OSGi, Java, and Eclipse RCP. Neil created the open source "BundleMonitor," an eclipse plug-in that allows you to view and manipulate OSGi bundles, services and configurations in the running Eclipse instance.

    #, I would love to have more insight in actual apps using OSGi apart from the app servers and embedded things. What Neil mentioned, where are the banking apps, and some of the like?

    Now, just to clarify, SOA is more the architecture using the service metaphor. SOA is not a pattern, nor is it the web service triangle displayed. The service is modeled used the triangle, not SOA.

    Fascinating the concept of components as living things. In one of my university works I presented the notion of passive objects against dynamic or active objects. These second ones would have the same properties Neil adds to components, like awareness of environment and responsiveness to it. Still, components do not require that as minimum. A component can be a dumb thing, passive.

    And of course, components using services to offer functionality is one of the ideas under SCA.

    At the end of the day, this proposal is about an SOA infraestructure (OSGi) used to create an COA application. Interesting.

    Funny. His definition of Components is precisely the same definition DAI people use for Agents.
