The above is actually not true. AS7 does not run on an OSGi Framework - it internally runs on a proprietary module system. AS7 *is* an OSGi framework in the sense that end users can deploy OSGi bundles in it and use it as any OSGi Framework, in a way similar to Equinox and Felix. Granted, AS7 contains more stuff that's not OSGi-related, but we can ignore that in this thread I think :) > So if there is another framework to be supported by Pax Runner (and Pax Exam > or any other Pax projects), it should be JBoss OSGi but not JBoss AS. JBoss OSGi is the subcomponent that adds the OSGi functionality to AS7 but the main distribution channel for this OSGi functionality is through AS7. Because AS7 is lightweight and starts up quickly there is generally no need to use the base subcomponent on its own... > From what I read here > https://docs.jboss.org/author/display/JBOSGI/Getting+Started > the project is only distributed in the form of an installer bundle.

Hmm, probably the easiest way to get this would be to download the jar from the above URL, unzip it and then launch /jboss-modules.jar which is an executable jar file. > (BTW, I never understood why JBoss stopped publishing their artifacts on > Maven Central. It just make everyone else's lives harder....) I don't know the answer to this question ;) > Next question: JBoss AS has its own launcher scripts, and I guess most > people don't even notice that there is now OSGi under the hood. So why would > anyone want to use Pax Runner to launch JBoss AS? So as mentioned earlier, it's not really OSGi under the hood - OSGi is actually a user feature which is built on top of an internal module system called JBoss Modules/MSC. The main reason why I was thinking of suggesting it for inclusion is for people who want to run or test their OSGi app in various Frameworks. Having AS7 supported in pax-runner will allow people to switch from Equinox, Felix, etc to AS7. I was also looking at the Eclipse integration that's mentioned here: http://eclipsesource.com/blogs/2009/08/14/eclipse-osgi-and-pax-runner/ is that still supported with pax-runner? > If you just want to launch the JBoss OSGi framework and provision some > additional bundles to it, you can use Pax Exam (Native Container or Server > Mode).

Yeah, I know you can also use it through mvn pax:run - I guess I just looked at the quickstart and there it talks about installing pax-runner...
