public class CXFBusImpl implements CXFBus {
private Bus bus;
@Activate
public void activator(ComponentContext context) {
// Make a bus factory so that the worker and front end, if
co-resident, don't share.
bus = BusFactory.newInstance().createBus();
// Set the class loader so we get the correct TCCL.
bus.setExtension(context.getBundleContext().getBundle().adapt(BundleWiring.class).getClassLoader(),
ClassLoader.class);
}
@Deactivate
public void deactivator() {
bus.shutdown(false);
}
@Override

}
}
