Hi BJ, Differences duly noted. But I'm left wondering if R4-DS (with its whiteboard/service binder concepts) is much more complex to implement compared to extension points (with its own version of DS embodied in the plugin.xml file) which in my mind is quite straightforward. Your comments are appreciated.

Yes, I would certainly like to try out your suggestion and load up those bundles. My only concern is if there could be some issues supporting two registries simultaneously (Felix bundle registry and Equinox extension registry). But perhaps this is a good strategy to maintain a separation of concerns. I understand from your recent book on RCP, you mentioned somewhere that the Equinox team felt it was not practical to convert extension points to plain OSGi services. But now it seems that this perception has changed with the adoption of declarative services for the extension point mechanism. Not knowing much about how Equinox implemented extension points, I had earlier implemented a similar but simplistic version of this concept using an IExtensionPoint service api in Felix (then Oscar). This was borne out of necessity (project deadline) more than anything else. P.S. I read your sample chapter on RCP (Chapter 2). Kudos on an excellent book! I would recommend it even if you are not into RCP since it has valuable info on Eclipse. -- rick -----Original Message----- From: Jeff McAffer [mailto:[EMAIL PROTECTED] Sent: Tuesday, November 28, 2006 8:17 PM To: felix-dev@incubator.apache.org Subject: RE: Felix and Eclipse PDE The Eclipse extension mechanism is an addon service/mechanism analogous to declarative services. That is, you should be able to take the org.eclipse.equinox.registry bundle (and its prereqs) from Equinox and use it on other frameworks. In the case of the registry I suspect you would need the o.e.equinox.common and o.e.equinox.supplement bundles. The latter supplies implementations of various services that are included in the Equinox system bundle as part of its implementation strategy. We are just redoing how we manage the supplement bundle so a new one will appear in builds soon (or already has). I know that people have run the registry on Knopflerfish. Perhaps you would be interested in trying it out on Felix and reporting back to the Equinox team?

I was wondering if anyone can provide an update on this issue. Is anyone from the Felix community working to make Eclipse and Felix interoperable? Is there some sort of timeline to implement extension points in Felix? If not, why not? Thanks!

This allows other OSGi frameworks to be launched like Equinox is (also it allows for reusability of the launch configuration UIs and other things). There is an OSGi framework extension point ( http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.pde.ui/schema/osgiFrameworks.exsd ) that interested OSGi frameworks can extend. Currently only Equinox is supported ( http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.pde.ui/src/org/eclipse/pde/ui/launcher/EquinoxLaunchConfiguration.java ) but we would appreciate feedback from the Felix community if someone would like to create a Felix extension. We want to make sure this API is stable for Eclipse 3.3 and would love if the Felix community could help the evolution of this API. If you have any questions using this API, please feel free to email the [EMAIL PROTECTED] mailing list.
