Project to build Jackson (http://jackson.codehaus.org) extension module (jar) to support datatypes of "json org" JSON library (see [http://json.org/java])

Status

Module is fully usable and officially released.

Usage

Maven dependency

To use module (version 2.x) on Maven-based projects, use following dependency:

<dependency>
  <groupId>com.fasterxml.jackson.datatype</groupId>
  <artifactId>jackson-datatype-json-org</artifactId>
  <version>2.4.0</version>
</dependency>

(or whatever version is most up-to-date at the moment)

Registering module

To use the the Module in Jackson, simply register it with the ObjectMapper instance:

// import com.fasterxml.jackson.datatype.jsonorg.JsonOrgModule;

ObjectMapper mapper = new ObjectMapper();
mapper.registerModule(new JsonOrgModule());

This will ensure that basic datatype of org.json package can be read and written using Jackson data-binding functionality.

Data conversions

After registering the module, you can read and write JSON to/from org.json.JSONObject similar to handling custom POJOs or standard JDK types:

JSONObject ob = mapper.readValue(json, JSONObject.class); // read from a source
String json = mapper.writeValue(ob); // output as String

As well as do conversion to/from POJOs:

MyValue value = mapper.convertValue(jsonObject, MyValue.class);
JSONObject jsonObject = mapper.convertValue(value, JSONObject.class);

or to/from Tree Model:

JsonNode root = mapper.valueToTree(jsonObject);
jsonObject = mapper.treeToValue(root, JSONObject.class);

Similarly, you can read/write/convert-to/convert-from JSONArray instead of JSONObject.
