OSGi Tutorial

by Peter Kriens, OSGi™ Fellow, and Director of Technology, aQute

This tutorial is a powerpoint presentation together with a number of example bundles. The powerpoint presentation will guide you to how to setup and use Eclipse to develop bundles. This page allows you to download the powerpoint presentation as well as all the solutions to the exercises. Note that these solutions are bundles, you can find the source code of these bundles in the OPT-INF/src directories.

This is an introductory tutorial. During the tutorial the OSGi features are presented with toy code. An extremely trivial chat system is developed. However, this is toy code and has no ambition to become a real chat system (though the architecture is sound). All code is highly optimized for being as small as possible showing the feature.

I have tried to make the tutorial as accurate as possible, but it has not been given very often. I therefore do appreciate if you provide feedback about any bugs you find. Have fun with it!

Getting Started with OSGi

by Neil Bartlett

Abstract: This webinar will be an introduction to OSGi: what it is, when you should use it and how to get started learning it.

OSGi is the powerful dynamic framework that underlies the Eclipse IDE and platform, but its use is not restricted to Eclipse. In fact it is used everywhere from mobile phone and vehicle entertainment systems to enterprise application servers. It is, essentially, the module system for Java.

The level of this talk will be introductory and will not assume prior knowledge of either OSGi or Eclipse (although knowledge of standard Java *will* be assumed). Also, we will discuss some aspects of OSGi that are not commonly used in Eclipse plug-in development, for example, usage of the Service Registry. So even experienced plug-in developers should get something from it.

Getting Started with OSGi

A tutorial series by Neil Bartlett

The following is a list of links to my tutorial series Getting Started with OSGi which is currently running on EclipseZone.

Unfortunately on EclipseZone the new posts push the older ones off the front page, so if you want to refer back to an earlier item in the series then you have to go digging through the forums.

Therefore for convenience I will be maintaining links to all parts of the series on this page.

Part 1: Your first bundle (PDF)
Part 2: Interacting with the Framework (PDF)
Part 3: Dependencies between Bundles
Part 4: Registering a Service
Part 5: Consuming a Service
Part 6: Dynamic Service Tracking
Part 7: Introducing Declarative Services
Part 8: Declarative Services and Dependencies

Creating an OSGi bundle

By Glen Normington, SpringSource

Friday, January 05, 2007

Newcomers to OSGi may like a simple guide to developing an bundle. Peter Kriens has provided an extensive tutorial which is a must for anyone serious about learning OSGi. However, it has a long introduction and assumes you are happy to run Eclipse. So I thought I would provide a trival example that people could get going using only a Java SDK and their favourite text editor.

Here are instructions to create and run a trivial bundle, hopefully in about 10 minutes.

Apache Felix OSGi Tutorial

This tutorial creates successively more complex OSGi bundles to illustrate most of the features and functionality offered by the OSGi framework.

Trails:

Apache Felix Tutorial Example 1: A bundle that listens for OSGi service events.
Apache Felix Tutorial Example 2: A bundle that implements a dictionary service.
Apache Felix Tutorial Example 2b: A bundle that implements another dictionary service.
Apache Felix Tutorial Example 3: A bundle that implements a simple dictionary service client.
Apache Felix Tutorial Example 4: A bundle that implements a more robust dictionary service client.
Apache Felix Tutorial Example 5: A bundle that implements a dictionary service client using the Service Tracker.
Apache Felix Tutorial Example 6: A bundle that implements a spell checker service using dictionary services.
Apache Felix Tutorial Example 7: A bundle that implements a spell checker service client.
Apache Felix Tutorial Example 8: A bundle that implements a spell checker service using Service Binder.

OSGi Tutorial, A Step by Step Introduction to OSGi Programming, Based on the Open Source Knopflerfish OSGi Framework

By Sven Haiges

This tutorial introduces you to OSGi programming based on the open source Knopflerfish OSGi framework. I chose Knopflerfish, because it is easy to install and provides a great desktop GUI, that will help you to get your first bundles deployed in an OSGi Framework.

First, the reader is quickly introduced to the installation of Knopflerfish. Second, you will create your first OSGi bundle and deploy it in this framework. Step by step, you will create more bundles, register and retrieve services and manage their dependencies. By the end of this tutorial, you should have a basic understanding of OSGi programming.

The OSGi Complete

By Dr. Pavlin Dobrev and Stoyan Boshev, ProSyst Software Labs

OSGi defines a huge set of services that are not well known to the application developers. Some of these services are Wire Admin, IO Connector, Initial Provisioning and Declarative Services. These services are donated to Eclipse in 2007 from ProSyst and it is expected to be included in the next Eclipse major release.

This tutorial will focus on main problems, solutions and code snippets related to the usage of the OSGi services. Some topics which will be addressed are:

OSGi Wire Admin Service Specification
OSGi IO Connector Service Specification
OSGi Initial Provisioning
OSGi Declarative Services Specification
Example Usage

The tutorial will include set of programming examples and demonstrations involving different OSGi services.

Getting started with Spring-OSGi

by Peter Doornbosch, luminis

26-Aug-2007

With the introduction of Spring OSGi, it becomes relatively easy to split up a Spring application in separate OSGi bundles, and have a much more modular application architecture, without all the classloading hassle you may encounter when deploying components in J2EE application servers.

Getting started with Spring-OSGi -- part 2

26-Sep-2007

In the previous blog entry about Spring-OSGi, we demonstrated how to develop a simple Spring-OSGi bundle that exposes a Spring bean as an OSGi service. In this installment we'll have a look at how you can use OSGi services in a Spring-OSGi bundle. The sample code used in this blog builds on the sample of the previous blog and can of course be downloaded from our site.
