Programmatically Start OSGi (Equinox)?

by

Any OSGi framework (R4.1 or later) can be started programmatically using the FrameworkFactory API:

ServiceLoader<FrameworkFactory> ffs = ServiceLoader.load(FrameworkFactory.class);
FrameworkFactory ff = ffs.iterator().next();
Map<String,Object> config = new HashMap<String,Object>();
// add some params to config ...
Framework fwk = ff.newFramework(config);
fwk.start();

The OSGi framework is now running. Since Framework extends Bundle you can call getBundleContext and call all of the normal API methods to manipulate bundles, register services, etc. For example

BundleContext bc = fwk.getBundleContext();
bc.installBundle("file:/path/to/bundle.jar");
bc.registerService(MyService.class.getName(), new MyServiceImpl(), null);
// ...

Finally you should simply wait for the framework to shutdown:

fwk.stop();
fwk.waitForStop(0);

To reiterate, this approach works for any OSGi framework including Equinox and Felix just by putting the framework JAR on the classpath.
