Simple Type Definitions

Binding XML Schemas

This section describes the default XML-to-Java bindings used by JAXB. All of these bindings
can be overridden on global or case-by-case levels by means of a custom binding declaration.
See the

JAXB Specification (http://java.sun.com/xml/downloads/jaxb.html)

for complete

information about the default JAXB bindings.

Simple Type Definitions

A schema component using a simple type definition typically binds to a Java property. Since
there are different kinds of such schema components, the following Java property attributes
(common to the schema components) include:

Base type

Collection type, if any

Predicate

The rest of the Java property attributes are specified in the schema component using the simple
type definition.

Default Data Type Bindings

The following sections explain the default schema-to-Java, JAXBElement, and Java-to-schema
data type bindings.

Schema-to-Java Mapping

The Java language provides a richer set of data type than XML schema.

Table 171

lists the

mapping of XML data types to Java data types in JAXB.
