Hi,

the products of commons are highly used throughout many projects.

It would be great, if the projects here at Apche Commons could help
those projects that are using OSGi.

OSGi is based around the concept of a bundle - a bundle is a jar file
with additional meta data like the packages it exports and a list of
external packages it is using (please forgive me if I'm simplifying here
too much).

As many projects are using artifacts from Apache Commons, they need the
specific jars as bundles. This is most often done by creating so called
wrapper bundles: these are jars that have the same contents as the
original library with the addition of the required meta data.
You can find several examples here:

http://svn.apache.org/repos/asf/felix/trunk/commons/

Now, it would be great, if the projects here at Apache Commons would
already provide artifacs that can be directly used in an OSGi environment.

All that has to be done is adding some entries to the manifest. This is
usually a list of imported packages, a list of exported packages, a
symbolic name for the bundle and a version. (There are some more but
these are the most important ones).

Adding these entries can be done by hand (not recommended) or with tools
automatically. For example the Apache Felix maven bundleplugin requires
just some lines of configuration and that's it.

It would be great if some of the projects here could add these meta data
as part of their next release. This will make the life of all projects
using OSGi much much easier.

So if you're interested in helping us, just let us know. We would be
happy to make the required changes to the poms or whatever needs to be
done. I cc'ed the Felix dev list as some Felix developers might not be
subscribed to the commons dev list, so please keep them cross posted.

Thanks
Carsten
