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.
