Re: [equinox-dev] Accessing files of a feature project during runtime

[Mark Hoffmann <mark.hoffmann@xxxxxx>]

Hi Simon,

Features or no bundles. they are no part of the OSGi specification and 
only related to Eclipse. Features can be seen as an meta-aggregation of 
bundle into a functionality description. It is more to ease the humans 
mind, when handling with large numbers of bundles and get them 
"categorized".

The OSGi there are subsystems, that are doing similar thing and even 
more, like isolation of visibility.

With features you can use the root files stuff [1] to copy files nearly 
wherever you like. Take notice that the stuff is bundled for deployment 
time. P2 uses the instructions to copy files.

But from my point of view, you should include your files into a bundle 
or a bundle-fragment. Especially during runtime it is the recommended 
way, because bundles are resolved by any OSGi resolver. Eclipse Features 
are not resolved during runtime from equinox. You have to use P2 for 
that, but even then, features are no real part of your runtime.

I hope it helps.

Regards,

Mark
