New issue 778 by [email protected]: RFE: Ability to delegate injection for unknown types
http://code.google.com/p/google-guice/issues/detail?id=778

Use-case: Jersey 2.0 depends on HK2 (an implementation of JSR330). In order to integrate Guice into Jersey 2.0 I am building a Guice-HK2 bridge whereby HK2 delegate to Guice for unknown types and Guice delegates to HK2 for unknown types (with a mechanism to prevent endless loops).

HK2 already has a mechanism to defer injection to Guice, but Guice does not provide a mechanism to defer injection to HK2. I tried using TypeListener and asking for help on the mailing list but there doesn't seem to be a way to implement this as of Guice 3.0.

When trying to inject the following:

@javax.inject.Inject
public DepartmentsResource(com.google.inject.Injector injector, javax.ws.rs.core.UriInfo uriInfo)

Guice understands @Inject, Injector but not UriInfo. It never invokes the TypeListener for DepartmentsResource or UriInfo, so I don't have the chance to register a MembersInjector to delegate injection to HK2.
