JSON Libraries

General data-binding functionality for Jackson: works on core streaming API

Gson is a Java library that can be used to convert Java Objects into their JSON representation. It can also be used to convert a JSON string to an equivalent Java object.

Core Jackson processing abstractions (aka Streaming API), implementation for JSON

Fastjson is a JSON processor (JSON parser + JSON generator) written in Java

JSON is a light-weight, language independent, data interchange format. See http://www.JSON.org/ The files in this package implement JSON encoders/decoders in Java. It also includes the capability to convert between JSON and XML, HTTP headers, Cookies, and CDL. This is a reference implementation. There is a large number of JSON packages in Java. Perhaps someday the Java community will standardize on one. Until then, choose carefully.
