Title

OSGi and Java EE in GlassFish

Overview

This session will provide an introduction to OSGi and explain how OSGi is used in GlassFish to provide a modular and light-weight App server. Attendees will learn how to manage the OSGi runtime in GlassFish and change the default runtime of Felix to Equinox and Knopflerfish. The talk will show how to create a simple OSGi application using CLI and IDEs and deploy them in GlassFish. Finally, it'll explain the how OSGi + Java EE hybrid application can be created and discuss their benefits.

Managing an OSGi Framework with Apache Felix Web Console

Overview

Initially created to aid in the simple maintenance of the OSGi framework and the application during the early development of Apache Sling, the Web Console soon attracted interest from the OSGi community. Three years later, the Apache Felix Web Console 3.0 has just been released and provides an extensible console for Web based management of an OSGi framework. This talk will introduce the functionality of the core Web Console as well as some of its existing plugins and the extension points of the Web Console where developers might want to hook up to. To round it up a simple Web Console plugin will be developed and deployed.

Tales from the OSGi trenches

Overview

In this talk we share our experience with the Apache Felix OSGi framework, used for a major rewrite of Day's family of content management products.
After more than three years working with OSGi, the impact on our products, developers, customers and service people is very high, in a positive way.
OSGi is no silver bullet either. The extreme modularization and dynamic service deployment features of OSGi make our products much more robust and maintainable, but the costs associated with changing people's way of thinking about code and modules, and with testing and debugging highly dynamic systems, must not be underestimated.
Based on real-life code samples, we will show how OSGi is used at several levels in our products, from low-level interactions with the framework to very simple creation of (compiled or scripted) services.
Sharing our experience will help you decide if OSGi is for you, and more importantly at which level you should use it.

Hello, RESTful OSGi world!

Overview

In this talk we present a small RESTful OSGi web application built from scratch, using powerful Maven plugins and OSGi compendium services to create, assemble, configure and start a set of OSGi bundles and services.
Using OSGi Maven plugins from the Apache Felix (maven-bundle-plugin, maven-scr-plugin) and Apache Sling (maven-launchpad-plugin) projects allows us to create our RESTful service with the bare minimum of code and configurations, using java annotations and just a few POM declarations to setup the required OSGi metadata, list of runtime bundles, OSGi services and configurable parameters.
The complete source code of our example app is provided to allow you to jumpstart your OSGi development, including example optional services to expose the OSGi plug-ins concept.

Managed JPA in an OSGi framework - getting the best of both worlds

Overview

The OSGi Alliance Enterprise Specifications release provides definitions and guidance for building enterprise technologies, such as Servlet containers, Object Relational Mapping frameworks, and JTA transaction managers, that can be used in an OSGi framework. This talk will describe benefits and limitations of the Java ^TM Persistence API (JPA) service defined by the OSGi Alliance Enterprise 4.2 release. Drawing on examples from the Apache Aries project, the talk will also demonstrate how a container implementer can build upon the existing specifications to provide managed JPA in an OSGi environment. Finally the talk will show how an OSGi JPA container can be integrated with the OSGi blueprint service to provide dependency injection, and a familiar programming model for JEE developers.
This session is intended for existing JEE and OSGi developers with an interest in learning more about how existing JEE technologies can be integrated and used in an OSGi environment.
