JSON Providers
Apache Wink provides a set providers that are capable of serializing a number of data models into JSON representations. There are currently 3 Apache Wink extensions that provide JSON support. Each has unique features that may make one more suitable for your particular application.
wink-json-provider (org.json)
The wink-json-provider extension is provided in the binary distribution and uses the JSON.org classes to provide JSON support. Include the wink-json-provider-<VERSION>.jar in the classpath and the providers will automatically be registered. You will also need the org.json JAR which is provided in the ext/wink-json-provider/lib folder.
org.apache.wink.providers.json.JsonProvider
Handles reading and writing of org.json.JSONObject classes for the application/json and application/javascript media types.

wink-jettison-provider (org.codehaus.jettison)
The wink-jettison-provider extension is provided in the binary distribution and uses the Jettison code to provide JSON support. Include the wink-jettison-provider-<VERSION>.jar in the classpath and the providers will automatically be registered. You will also need the Jettison library JARs which are provided in the ext/wink-jettison-provider/lib folder.
By default, reading is currently disabled due to issues with the reader. You can enable it by calling setUseAsReader(boolean) on each provider and registering as a singleton in the JAX-RS Application sub-class.
org.apache.wink.providers.jettison.JettisonJAXBElementProvider
Handles reading and writing of JAXBElement classes for the application/json media type.

Jackson JSON Processor
