Hi Evan, see my comments inline.

Yes this can be done. You have the ability to configure this through the configuration admin service. Another reason to take a look at Karaf, cause it will bring you all the needed parts out-of-the-box, and you are still able to "down-strip" it if you like. > 3.

OSGi Jars with Activator, through blueprint.xml definitions - using the whiteboard-pattern or by deploying either WARs with and without OSGi Manifests. What ever you deploy is up to you. So the hardening is mainly your part in either allowing or disallowing to install certain bundles after the system is up-to date. > What are the disadvantages of using embedded Felix?

I'm repeating myself, I suggest taking a look at Apache Karaf it uses Felix as the OSGi Framework and it'll give you a lot of other extra features that come very handy when migrating a application to the osgi world. > > Thanks, > > E > > On Fri, Jun 15, 2012 at 2:57 AM, Achim Nierbeck > <[email protected]>wrote: > >> And if you want to have some more stuff like JAAS or Logging out of >> the box working for you >> use Apache Karaf which uses Felix as the OSGi framework and brings >> along everything you need for Pax Web :) >> >> regards, Achim >> >> 2012/6/15 Allen Lau <[email protected]>: >> > Unless you really need to embed Felix, why not run the Felix distribution >> > and add something like Pax-Web which embeds Jetty to be >> > your WAR/WAB web container? >> > >> > On Thu, Jun 14, 2012 at 2:03 PM, Evan Ruff >> > <[email protected]>wrote: >> > >> >> Hey guys, >> >> >> >> I'm just getting started with Felix and OSGi in general.
