What I've been doing is allowing Guice to create my WebApplication
instance and injecting that into my own GuiceServletContainer which
overrides the create() method to return the injected WebApplication.
If you do that, then you can do something like what I have here
<
http://pastie.org/583188>. It's in Scala, but you should be able to
get the idea.
I also talked with Paul once about taking it a bit further. It
requires exposing more of the Jersey services so they could be
injected using Guice 2.0's custom integrations. The biggest drawback
is that they wouldn't be injectable into the constructor that way,
only on fields and methods. But it would be better than nothing I
figure. Unfortunately, I haven't found the time to follow up on this.
Maybe you can?
