JAXB API Source Code

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.

/**
 * <p>
 * A container for multiple @{@link XmlElement} annotations.
 *
 * Multiple annotations of the same type are not allowed on a program
 * element. This annotation therefore serves as a container annotation
 * for multiple &#64;XmlElements as follows:
 *
 * <pre>
 * &#64;XmlElements({ @XmlElement(...),@XmlElement(...) })
 * </pre>
 *
 * <p>The {@code @XmlElements} annotation can be used with the
 * following program elements: </p>
 * <ul>
 *   <li> a JavaBean property </li>
 *   <li> non static, non transient field </li>
 * </ul>
 *
 * This annotation is intended for annotation a JavaBean collection
 * property (e.g. List). 
 *
 * <p><b>Usage</b></p>
 *
 * <p>The usage is subject to the following constraints:
 * <ul>
 *   <li> This annotation can be used with the following
 *        annotations: @{@link XmlIDREF}, @{@link XmlElementWrapper}. </li>
 *   <li> If @XmlIDREF is also specified on the JavaBean property,
 *        then each &#64;XmlElement.type() must contain a JavaBean
 *        property annotated with {@code @XmlID}.</li>
 * </ul>
 *
 * <p>See "Package Specification" in javax.xml.bind.package javadoc for
 * additional common information.</p>
