JSON-B is an API for converting Java objects to/from JSON messages in a standardized way. It defines a default mapping algorithm to convert Java classes to JSON and still lets you customize your own algorithms.

With JSON-B, Java EE now has a complete set of tools to work with JSON, such as JSON API, and JSON-P. No third-party frameworks are needed anymore (although you are still free to use them).

This quick recipe will show you how to use JSON-B to convert a Java object to and from a JSON message.
