I need a fast way to extract data from json responses a I get from a webservice.

By fast, I mean fast for the programmer, not necessarily for the computer.

I was thinking of something like Xpath for Json, if such a thing exists.

Any ideas? I am open to any Java Json library. In fact, the easiness to extract data from Json with a powerful querying language will be central to the choice of json library.

Jackson JSON Processor has been used in a lot of frameworks. The tree model or data binding approach is probably the easiest to work with.

JsonPath emerged as a de facto standard for such tasks. A Java implementation:

It seems well maintained and works fine.

Similar to @alexis-dufrenoy's answer -- but it looks like a more active project.

Disclaimer: I have not tried @nebhale's system, so I can't judge which is best.
