Hi Martin,
Grrr... that is odd as the InjectableProvider is used extensively by
Jersey itself.
I just wrote a simple test example, with the InjectableProvider as
inner class of a servlet that overrides the initiate method, and it
works fine for me using the latest 0.9 SNAPSHOT build. I am taking
the rest of the day off, but i will try and send the example to you
either this evening or tomorrow.
Paul.
