Your solution helps but it's for Jackson 1.x and not for Jackson
2.3.1. (I'm using Jackson 2 because another component depends on it.)
This SO question is asking the same thing [1] but the answer [2]
exhibits the same problem that I'm running into, which is that Jersey
ends up with TWO Jackson providers registered.
So I'm still in the same situation: I either need to get access to the
Jackson provider that Jersey auto-discovers (so that I can configure
its ObjectMapper), or I need to disable the auto-discovery so I can
explicitly register my own provider.
Please help!
