In this presentation from SpringOne 2009, Rob Harrop discusses OSGi in the enterprise, OSGi basics, modularity in OSGi, import-package, require-bundle, the problem of split packages, import-bundle, Bundlor, demos of OSGi bundle usage, RFC 66, dm Server, the blueprint service, OSGi services, demo of building an OSGi-based Spring MVC web application, OSGi configuration admin, and dynamic updates.
It's been a long time since the last Bundle.update was posted, and there have been a lot of OSGi-centric updates since then. OSGi 4.2 has been released, with Equinox 3.6, Felix 3.0 and Knopflerfish 3.0 all providing support for the new platform. Recently, there have been some glimpses of the next version of OSGi, as well as increased enterprise support. Read on to find out what's been happening.
Peter Kriens, technical director of the OSGi alliance, gave a presentation on the upcoming OSGi 4.2 release at the UK OSGi Users Group. The event was recorded, and the video is now available. OSGi 4.2 is expected to be released to the public by the end of August 2009 and includes a number of new features.
As part of the upcoming Eclipse Ganymede release which is scheduled for June 25th, InfoQ will cover a series of Eclipse subprojects. Today, the subproject is Equinox p2 (Provisioning Platform), which is a framework for provisioning Eclipse-based applications. InfoQ spoke with Jeff McAffer and Pascal Rapicault to learn more about p2 and what it provides.
OSGi is specification of a Java-based framework targeted for use by systems that require long running times, dynamic updates, and minimal disruptions to the running environment. The Eclipse Equinox provides one of many available implementations. Numerous server and desktop applications are also starting to make use of OSGi.
Modularity is an important aspect of large Java systems. Build scripts and projects are often split up into modules in order to improve the build, but this is rarely taken into account at runtime. This third part of the Modular Java series discusses dynamic modularity, how a bundle's classes are resolved, how they can come and go, and how they can communicate with each other.
Modularity is an important aspect of large Java systems. Build scripts and projects are often split up into modules in order to improve the build, but this is rarely taken into account at runtime. This second part of the Modular Java series discusses static modularity, the creation of bundles, how to install them into an OSGi engine and how to set up (versioned) dependencies between bundles.
Eclipse RAP (Rich Ajax Platform) in the real world is covered in this case study which looks at how CAS Software AG used RAP on a recent new product offering. Eclipse Equinox is also used by CAS and covered in the case study.
