== Your First OSGi Bundle Using CLI ==
This is an example of creating a Hello World OSGi bundle using CLI (Command Line Interface) on Fedora. You can find the original work at [http://underlap.blogspot.com/2007/01/creating-osgi-bundle.html].

* Open a terminal window and create this directory path.

     mkdir -p org/foo/example

* Copy this file, with name Example.java, into the example directory

     package org.foo.example;
     import org.osgi.framework.BundleActivator;
     import org.osgi.framework.BundleContext;
     public class Example implements BundleActivator {
         public void start(BundleContext bc) {
             System.out.println("Hello world");
         }
         public void stop(BundleContext bc) {
             System.out.println("Goodbye world"); 
         }
     }

* Compile the Java program with this command

     javac -cp /usr/lib64/eclipse/plugins/org.eclipse.osgi_3.6.1.R36x_v20100806.jar org/foo/example/Example.java

* Copy this file, with name MANIFEST.MF, into your home directory

     Manifest-Version: 1.0
     Bundle-ManifestVersion: 2
     Bundle-SymbolicName: org.foo.example.Example
     Bundle-Version: 1
     Bundle-Activator: org.foo.example.Example
     Import-Package: org.osgi.framework;version="1.3.0"

* Create a jar file of the manifest and java program with this command

     jar -cvfm example.jar MANIFEST.MF org

* Now run the bundle using the Equinox console

     java -jar /usr/lib64/eclipse/plugins/org.eclipse.osgi_3.6.1.R36x_v20100806.jar -console

* You should get the osgi> prompt and your session might look like this

     osgi> ss
     Framework is launched.
     id      State       Bundle
     0       ACTIVE      org.eclipse.osgi_3.6.1.R36x_v20100806
     osgi> install file:example.jar
     Bundle id is 1
     osgi> ss
     Framework is launched.
     id      State       Bundle
     0       ACTIVE      org.eclipse.osgi_3.6.1.R36x_v20100806
     1       INSTALLED   org.foo.example.Example_1.0.0
     osgi> start 1
     Hello world
     osgi> stop 1
     Goodbye world
     osgi> close

* Congratulations! You've just run your first OSGi bundle using the command line on Fedora Linux.
