FYI, the extender and whiteboard patterns are different! the whiteboard pattern (which is mentioned in the KF docs) is a replacement for the classic Listener pattern that uses the service registry to track listeners the extender pattern tracks bundles and acts on special metadata to extend the OSGi platform without bloating the API (Spring-OSGi is a good example) both approaches can be used to help register servlets with the HTTP Service :) -- Cheers, Stuart
