If you use declarative services to manage your component, you may implement two lifecycle methods in your component: // called when the component is activated (aka started) protected void activate(ComponentContext context); // called when the component is deactivated (aka stopped) protected void deactivate(ComponentContext context); Depending on how you inject the HttpService to you component (I assume your component is a Servlet, right ?) you may register the component with the HttpService upon activate and unregister upon deactivate. For an example, you might want to look at the OsgiManager servlet [1] of the Felix Web Console. Hope this helps.
