Jettison is a collection of StAX parsers (streaming API for XML) and
writers which read and write JSON (JavaScript Object Notation). This
allows nearly transparent enablement of JSON based web services in
services frameworks like Apache CXF.
.
There are currently two included conventions for mapping JSON to XML.
The first is BadgerFish which implements the full XML infoset in JSON
using various techniques. The second is called the "mapped"
convention. It allows you to manually map XML namespaces to JSON
element prefixes.
