December 16, 2008 – OSGi
OSGi is a Java-based component architecture that has gained a lot of traction recently. It is simple, provides dynamic updates of components and supports working with different versions of the same JAR or component. OSGi is used to build complex applications like Eclipse, application servers (GlassFish, IBM Websphere, OpenEJB, Oracle/BEA Weblogic, Jonas, JBoss), application frameworks (Spring, Guice), and more. We will discuss the following topics:
• The basic OSGi architecture (bundles, manifests and services)
• OSGi Implementations (Equinox, Felix, Knopflerfish)
• Concrete Uses of OSGi (Eclipse, …)
• Developing OSGi Bundles (Eclipse PDE, Maven, PAX-tools, …)
• OSGi Examples
