Chapter 16. Binding between XML Schema and Java Classes

16. Binding between XML Schema and Java Classes

The Java™ Architecture for XML Binding (JAXB) provides a fast and convenient way to bind between XML schemas and Java representations, making it easy for Java developers to incorporate XML data and processing functions in Java applications. As part of this process, JAXB provides methods for unmarshalling XML instance documents into Java content trees, and then marshalling Java content trees back into XML instance documents. JAXB also provides a way to generate XML schema from Java objects.

JAXB 2.0 includes several important improvements to JAXB 1.0:

  • Support for all W3C XML Schema features. (JAXB 1.0 did not specify bindings for some of the W3C XML Schema features.)

  • Support for binding Java-to-XML, with the addition of the javax.xml.bind.annotation package to control this binding. (JAXB 1.0 specified the mapping of XML Schema-to-Java, but not Java-to-XML Schema.)

  • A significant reduction in the number of generated schema-derived classes.

  • Additional validation capabilities through the JAXP 1.3 validation APIs.

  • Smaller runtime libraries.

This chapter describes the JAXB architecture, functions, and core concepts. You should read this chapter before proceeding to the examples, which provide example code and step-by-step procedures for using JAXB.
