From what I can find online, the state of the art for Guice + Jersey integration has stagnated since 2008 when it appears both teams reached an impasse. The crux of the issue is that JAX-RS annotations perform field and method injection and this doesn&#39;t play nicely with Guice&#39;s own dependency injection.

A few examples which I&#39;ve found don&#39;t go far enough to elucidate:

* Iqbalyusuf&#39;s post on [Jersey + Guice on Google App Engine Java][1] suffers from a lot of boilerplate (manually getting and calling the injector). I want binding and injection should happen behind the scenes via Guice annotations.

* Jonathan Curran&#39;s article [Creating a RESTful service with Jersey, Guice, and JSR-250][2] gave me hope because it&#39;s much more current (2010), but went no further than showing how to start up a Jersey service inside of a Guice ServletModule. However, there are no examples of doing any real dependency injection. I suppose that was left as an exercise for the reader. Curran&#39;s post may in fact be the correct first step towards wiring up Guice and Jersey and so I plan on starting with that.

* tantalizingly [James Strachan writes][3]:
&gt; JAX-RS works well with dependency
&gt; injection frameworks such as Spring,
&gt; Guice, GuiceyFruit or JBossMC - you
&gt; can basically pick whichever one you
&gt; prefer.

  But I see no evidence that is true from a practitioner&#39;s point of view.


What I find lacking are practical examples and explanations on how to combine JAX-RS and Guice annotations. For instance:

* I believe I cannot use constructor injection with any resource as Jersey wants to control this
* I&#39;m uncertain whether I can combine @Inject with @PathParam, @QueryParam, et al.
* How to use injection in a MessageBodyWriter implementation

Does anyone have examples, preferably with source, of non-trivial application which combines Jersey and Guice without sacrificing one or the other in the process? I&#39;m keeping on this road regardless, but the bits and pieces on the Jersey and Guice lists makes me think I&#39;m repeating the work of others who came before me.
