Castor is an open source data binding framework for Java. It's the shortest path between Java objects, XML and relational tables. Castor provides Java-to-XML binding, Java-to-relational persistence, and more.

This project provides a Castor JDO-specific implementation of the Spring ORM module, allowing users to use Spring ORM as their preferred choice of dealing with the persistence aspects of their applications whilst using Castor JDO as underlying persistence provider.

The project targets the Reference Implementation of JSR235 - Service Data Objects. The current source code while mature enough to be included in shipped BEA products is not yet finished as a JSR reference implementation.

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.
