 <p>This chapter describes how to use JPA with the Java Architecture for XML Binding (JAXB)&mdash;the Java EE standard for mapping POJOs (Plain Old Java Objects) to XML&mdash;and its Mapping Objects to XML (MOXy) extensions to map JPA entities to XML. Mapping JPA entities to XML is useful when you want to create a data access service with Java API for Restful Web Services (JAX-RS), Java API for XML Web Services (JAX-WS), or Spring.</p>
