Jackson Java JSON Processor

Jackson is a Java-based JSON-processing package that contains:

• high-performance streaming JSON parser/generator
• Tree Model that can be built from/written to parser/generator
• Object Mapper that implements data binding to/from parser/generator

API of streaming parser/generator is similar to Stax API used for efficient xml processing on Java platform.

Beyond VERY fast Json parser and generator, Jackson project also offers full data binding support through 2 different approaches: “Object Mapper” for full POJO to/from Json data mapping (similar to JAXB2) and “Tree Mapper” for something similar to DOM and XPath.
