Java Architecture for XML Binding (JAXB) is a Java API that allows Java developers to map Java classes to XML representations.

jaxb-api-2.3.1.jar is the JAR file for the JAXB API 2.3 specification. You can download and use it directly without any building process as shown in the last tutorial.

If you want to rebuild the JAR file, you can download the source code at JAXB API Maven Website.

 * <h3>Terminology</h3>
 * <p>
 * <b>JavaBean property and field:</b> For the purposes of
 * mapping, there is no semantic difference between a field and
 * a JavaBean property. Thus, an annotation that can be applied
 * to a JavaBean property can always be applied to a
 * field. Hence in the Javadoc documentation, for brevity, the
 * term JavaBean property or property is used to mean either JavaBean
 * property or a field. Where required, both are explicitly
 * mentioned.
 * <p>
 * <b>top level class:</b> For the purpose of mapping, there is
 * no semantic difference between a top level class and a
 * static nested class. Thus, an annotation that can be applied
 * to a top level class, can always be applied to a nested
 * static class. Hence in the Javadoc documentation, for
 * brevity, the term "top level class" or just class is used to
 * mean either a top level class or a nested static
 * class.
 * <p>
 * <b>mapping annotation:</b>A JAXB 2.0 defined program
 * annotation based on the JSR 175 programming annotation
 * facility.
 * <h3>Common Usage Constraints</h3>
 * <p>The following usage constraints are defined here since
 * they apply to more than annotation:
 * <ul>
 * <li> For a property, a given annotation can be applied to
 * either read or write property but not both. </li>
 * <li> A property name must be different from any other
 * property name in any of the super classes of the
 * class being mapped. </li>
 * <li> A mapped field name or the decapitalized name of a
 * mapped property must be unique within a class. </li>
 * </ul>
 * <h3>Notations</h3>
 * <b>Namespace prefixes</b>
 * <p>The following namespace prefixes are used in the XML Schema
 * fragments in this package.
 * <p>
 * <table class="striped" summary="XML Schema fragments namespace prefixes">
 *   <thead>
 *     <tr>
 *       <th scope="col">Prefix</th>
 *       <th scope="col">Namespace</th>
 *       <th scope="col">Notes</th>
 *     </tr>
 *   </thead>
 *   <tbody>
 *     <tr>
 *       <th scope="row">xs</th>
 *       <td>http://www.w3.org/2001/XMLSchema</td>
 *       <td>Namespace of XML Schema namespace</td>

 *     </tr>

 *       <th scope="row">xsi</th>

 *       <td>XML Schema namespace for instances</td>
