Most of the time, this occurs when the runtime can't find the Jackson library. Have you added the Jackson JARs to your Eclipse project and added them to your build path?

Hi Vinny,

Presuming the OP is using Maven (which I am), isn't this a bug in the "Google Client API" maven project? If that project requires Jackson to work, then it should indicate Jackson as a dependency. In that case, any of us depending on "Google Client API" should be enough, and it will transitively register a dependency on Jackson. It will do this IMPLICITLY, without any of us needing to explicitly indicate that dependency. As we don't actually depend on Jackson directly, it would be bad design for us to explicitly list it due to knowledge of internal implementation of "Google Client API."

I am having this error too, but I depend on some older versions of GAE SDK. I will update those first to see if it resolves itself, otherwise I'll use your approach and just force-depend on Jackson (despite having no direct dependency).

Thanks,

-b

(details: I currently use version 1.9.21 in my GAE maven dependencies)

Hey Benjamin,

That would be a correct analysis, but I have the sneaking suspicion that OP is not using Maven, and thus has forgotten to include the relevant jar dependencies for the API client library.
