Hi again...
I uploaded an example on using the component dsl.
https://github.com/csierra/osgi-jaxrs-extracted/pull/8/commits/12f92a61d0e8cd0dbf630a806ac0a31af1ca5934#diff-b7c2953bc9bc598a22c5481f9681e181R120
so this basically tracks every service with a property
jaxrs.application.select. For each of those it looks for any
CXFJaxRsServiceRegistrator that matches the filter contained in the
jaxrs.application.select property of the other service. When it finds a
match it registers the endpoint in the registrator.
When any of the dependencies, be it the service or the registrator, goes
away it closes the "branches" corresponding to those instances closing
the trackers and unreferencing the services. The idea is to build a
fairly complete set of "primitives" that allow to operate with services
in a safe way trying to avoid leaks as much as possible.
Here
https://github.com/csierra/osgi-jaxrs-extracted/pull/8/commits/12f92a61d0e8cd0dbf630a806ac0a31af1ca5934#diff-b7c2953bc9bc598a22c5481f9681e181R103
you can see another snippet. In this case it registers two services in
the framework, a Bus and a Servlet. When any of the dependencies goes
away the services are unregistered. Together with the "primitives" for
configuration you can get something quite similar to STATIC in DS but
without the need of any annotation and using the original third party
classes.
This is just a first approach. I would like to refine the set of
primitives to make them as useful as possible.
One obvious caveat is the horrible syntax. On a bright side, it should
be possible to use this from Scala confortably.
Carlos.

Thx ! Do you have a few tests / examples that could demonstrate the
possibilities of this dsl ?

Hello All,
My very shy colleague Carlos has just added a very nice new
project in Aries here [1] called "component-dsl"
It's a functional DSL for OSGi.
