Architectural Overview

Figure 17–1 shows the components that make up a JAXB implementation.

Figure 17–1 JAXB Architectural Overview

A JAXB implementation consists of the following architectural components:

• Schema compiler: Binds a source schema to a set of schema-derived program elements. The binding is described by an XML-based binding language.

• Schema generator: Maps a set of existing program elements to a derived schema. The mapping is described by program annotations.

• Binding runtime framework: Provides unmarshalling (reading) and marshalling (writing) operations for accessing, manipulating, and validating XML content using either schema-derived or existing program elements.
