I tried to run p2 on top of Felix - what I managed to get is simple
configurator installing p2 bundles on top of Felix in the way Eclipse does it:
put simple configurator in Felix auto deploy folder
describe all the other bundles in the bundle.info.
Though the initiative was unsuccessful as a whole, here are some interesting
things that could be useful:
- Felix default start level is 1 and this could potentially cause
issues with simple configurator which is supposed to be the only bundle running
on 1.
- Simple configurator relies on file schema which to be retrieved from
bundle location. It seems Felix bundle location doesn't provide this info.
- Relative paths in bundles.info lead to FileNotFoundException.
Last two could be worked around by having absolute path to bundles and
"file:" prefix in bundles.info (which is acceptable only for test purposes)
- p2 bundles should be ordered in order to start successfully
- Dependencies marked as "optional" in Manifest should be handled
properly in order to prevent ClassNotFoundException
- Dependencies to "org.eclipse.*" packages provided by Equinox (the
depending packages are around 10).
I'd like to participate.
Kind regards,
Katya

Subject: Re: [p2-dev] Working with Apache Felix
Nicholas are you interested in using all of p2, or just some of its sub
components?
As DJ said, this is something that we tried two years ago but we had to stop
because of corporate priorities on other projects.
I would be very happy to see this effort resurrected. I think most of the
effort required to make this happens consists in either making some of p2
dependencies on some Equinox packages or splitting up the Equinox packages used
by p2 into separate bundles. Then there is the work on providing a fwk admin
that knows how to work with Felix.
Is anyone interested in participating?
