Jackson

JSON is a light-weight, language independent, data interchange format.

Jackson can be used either to parse JSON strings, or to generate JSON data.

Beyond basic JSON reading/writing (parsing, generating), it also offers full node-based Tree Model, as well as full OJM (Object/Json Mapper) data binding functionality.
