Hi Sam,
I am not able to reuse the guice servlet module. I checked the sources
and Guice turned out to be dead simple when it comes to scopes. So it
really surprised me that I am just free to use any means I want to store
and maintain scoped instances.
I just wrote a custom member injector referring to the RequestContext
object bound to the current thread directly and it was done. I was really
concerned that I would miss something might result into a side effect that
I should have been aware of, but it appears to be side effect free.
Cheers,
Martin (Kersten)
