Here is the simple Osgi application with Equinox framework and I use Maven as build tool. The structure of this project is described in follow:

ows-osgi-tutorial
--src
|--main
|--java (contains all java source files)
|--resources
|--META-INF
|--MANIFEST.MF

The manifest file has content:

Manifest-Version: 1.0
Bundle-Name: Helloworld
Bundle-SymbolicName: Helloworld
Bundle-Version: 1.0.0
Bundle-Description: Hello world sample bundle
Bundle-Vendor: NextSS company
Bundle-Activator: ows.osgi.sample.Activator
Bundle-Category: Tutorial
Import-Package: org.osgi.framework

The POM file has content:

 
<?xml version="1.0" encoding="UTF-8"?>
&lt;project xmlns="<a href="http://maven.apache.org/POM/4.0.0">http://maven.apache.org/POM/4.0.0"</a>
xmlns:xsi="<a href="http://www.w3.org/2001/XMLSchema-instance">http://www.w3.org/2001/XMLSchema-instance"</a>
xsi:schemaLocation="<a href="http://maven.apache.org/POM/4.0.0">http://maven.apache.org/POM/4.0.0</a>
                    <a href="http://maven.apache.org/maven-v4_0_0.xsd">http://maven.apache.org/maven-v4_0_0.xsd"</a>&gt;
&lt;modelVersion&gt;4.0.0&lt;/modelVersion&gt;
&lt;groupId&gt;ows&lt;/groupId&gt;
&lt;artifactId&gt;ows-osgi-tutorial&lt;/artifactId&gt;
&lt;packaging&gt;jar&lt;/packaging&gt;
&lt;dependencies&gt;
&lt;dependency&gt;
&lt;groupId&gt;org.eclipse&lt;/groupId&gt;
&lt;artifactId&gt;osgi&lt;/artifactId&gt;
&lt;version&gt;3.2.1.R32x_v20060919&lt;/version&gt;
&lt;scope&gt;provided&lt;/scope&gt;
&lt;/dependency&gt;
&lt;/dependencies&gt;
&lt;build&gt;
&lt;plugins&gt;
&lt;plugin&gt;
&lt;groupId&gt;org.apache.maven.plugins&lt;/groupId&gt;
&lt;artifactId&gt;maven-jar-plugin&lt;/artifactId&gt;
&lt;configuration&gt;
&lt;archive&gt;
&lt;!--Maven generate the default manifest file, these statements in --&gt;
&lt;!--plugin section will force Maven use your own manifest file--&gt;
&lt;manifestFile&gt;src/main/resources/META-INF/MANIFEST.MF&lt;/manifestFile&gt;
&lt;/archive&gt;
&lt;/configuration&gt;
&lt;/plugin&gt;
&lt;/plugins&gt;
&lt;/build&gt;
&lt;/project&gt;

And we write the simple Activator class for Helloworld bundle:

 
package ows.osgi.sample.Activator;
import org.osgi.framework.BundleActivator;
import org.osgi.framework.BundleContext;
 
public class Activator implements BundleActivator {
public void start(BundleContext context) {
  System.out.println("Start helloworld service");
}
 
public void stop(BundleContext context) {
  System.out.println("Stop hello world service");
}
}

Open the console and type mvn package, you will have the jar file ows-osgi-tutorial-0.0.1.jar and it is done. You can deploy this bundle to any osgi-compliant framework as felix or equinox. I have tested on equinox by following commands:

- Start equinox: follow equinox guideline.
- Install the bundle: %osgi-console%> install <path of ows-osgi-tutorial-0.0.1.jar >
- Check whether the bundle install: %osgi-console%> ss (you will get the bundle of installed bundle by this command too).
- Start bundle: %osgi-console%>start <bundle id>

It is simple, right? It's time for you to create the more complicated tutorial, just modify the manifest file and Activator class. The build system is ready for use without any change.
