Virgo Kernel and Felix [message #754243]

Yesterday I downloaded Virgo Kernel and started using it. When I ran "help" from the osgi> console, I saw that Virgo Kernel uses a number of console commans from the Felix project. How are Virgo Kernel and Felix related? Does Virgo Kernel use both/either Equinox and Felix?

My guess was that Virgo Kernel uses the console commands from felix that get thier information from the standard osgi set of interfaces. Is this the limit to the use of Felix in Virgo, or is it larger?

Virgo uses the Equinox Incubator Console [1], based on Apache Felix Gogo shell. Gogo is is the reference implementation of RFC 147 - the Command Line Interface specification in OSGi. Besides Gogo the Equinox shell has ssh and telnet, JAAS based user authentication and tab completion.

Some Felix components were used in previous versions, but currently Virgo is entirely based on Equinox/Eclipse components, except Gogo of course. It should be possible to use the corresponding Felix equivalents that implement the same part of the OSGi spec (event admin for instance).

Just a small clarification: the spec work on RFC 147 was terminated because it was agreed there was no need for it now that Gogo is generally usable. So Gogo is not an official Reference Implementation of an OSGi spec, although from a user's perspective, it's pretty close to that.
