Castor is an open source data binding framework for moving data from XML to Java programming language objects and from Java to databases. It’s the shortest path between Java objects, XML documents and relational tables. Castor provides Java-to-XML binding, Java-to-SQL persistence, and more.

Castor is made up of (independent) modules as follows:- Castor XML
- Castor XML – Code generator
- Castor JDO – Persistence framework
- Castor JDO – DDL generator
- Additional tools
- Integration with other frameworks
Castor XML
XML data binding framework to bind XML artefacts to Java objects and vice versa.
Castor XML code generator

Castor JDO
