JiBX is a framework for binding XML data to Java objects. It lets you work with data from XML documents using your own class structures. The JiBX framework handles all the details of converting your data to and from XML based on your instructions. JiBX is designed to perform the translation between internal data structures and XML with very high efficiency, but still allows you a high degree of control over the translation process.

Subprojects include JiBX/WS for fast web services based on JiBX, and JiBX/OTA for working with Open Travel Alliance XML schemas and messages.
