@Component spring beans are not scanned automatically when bundle gets installed

Hi,
great example. When I installed the bundle the classes annotated with @Component have never been loaded.
So I had to add META-INF/spring/application-context.xml for explicit component-scan declaration and now the example  WebScripts are shown and executable.
Maybe there's a simpler solution getting components scanned and loaded automatically.
