Project to build Jackson (http://jackson.codehaus.org) module (jar) to support JSON serialization and deserialization of Joda (http://joda-time.sourceforge.net/) data types.

As of version 2.0 module is usable and relatively extensive (more so than in-built support 1.9 had). Contributions are welcome!

To use module on Maven-based projects, use following dependency:

<dependency>
  <groupId>com.fasterxml.jackson.datatype</groupId>
  <artifactId>jackson-datatype-joda</artifactId>
  <version>2.1.1</version>
</dependency>    

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

Like all standard Jackson modules (libraries that implement Module interface), registration is done as follows:

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

after which functionality is available for all normal Jackson operations: you can read JSON as Joda types, as well as write Joda values as JSON.
