Prerequisites

Please download and read the first chapter of the free ebook "Osgi in practice" (1). The direct download link is (2)

You need also to install the bnd plugin (3). Simply download the stable jar version in the plugins/ folder of your eclipse installation, and then restart it.

Get the code of chapter 1

to get the code, type

svn co http://osgitutorials.googlecode.com/svn/oip_ch1/trunk

Note: you need to read the first chapter of Osgi in Practice (2) to understand how to use the code

Three bundles are included:

• the "Hello World" bundle
• a "Bundle Counter" bundle
• a "Bundle Deployer" bundle (have a look at the Bundle Activator and to the Deployer Thread )

The code of the three bundles is actually mixed, but they're built using a different .bnd file (respectively helloworld.bnd, bundlecounter.bnd and bundledeployer.bnd)

To build yourself a bundle (using the Bnd eclipse plugin), simply right click on a .bnd file and choose "Make Bundle"

the Bundle Deployer bundle

The Bundle Deployer bundle is a possible solution for the exercises proposed at the end of the chapter. This bundle monitor the bundle/ folder contents and when finds a new bundle, deploy it when a jar is deleted from the directory, uninstall the correspondend bundle when a jar is updated in the directory, update the correspondent bundle
