Injection of Bundle/BundleContext into Java EE components

Hi all,

I was thinking about adding support for injection of
Bundle/BundleContext objects into Java EE components via @Resource
annotation. Example:

class MyServlet extends HttpServlet {
   @Resource
   Bundle bundle;
   @Resource
   BundleContext bundleContext;
   ....
}

That should make it easier to interact with OSGi within Java EE apps.

I was also thinking of something similar with @Inject for web beans
(cdi stuff) but I'm not really sure it's all that useful since it
should be possible to inject Bundle/BundleContext via @Resource or
combine it with @Produces.

What do you think?

Hi

Sounds useful!  I wonder if we want to support injecting both or just
bundleContext, since it is pretty straightforward to get bundle from
bundleContext (or the other way around).

dunno about the @Inject (seems like a good idea but I don't know enough about jcdi)  but the @Resource is a great idea!
