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.

/**
 * JAXP {@link javax.xml.transform.Result} implementation
 * that unmarshals a JAXB object.
 * 
 * <p>
 * This utility class is useful to combine JAXB with
 * other Java/XML technologies.
 * 
 * <p>
 * The following example shows how to use JAXB to unmarshal a document
 * resulting from an XSLT transformation.
 * 
 * <blockquote>
 *    <pre>
 *       JAXBResult result = new JAXBResult(
 *         JAXBContext.newInstance("org.acme.foo") );
 *       
 *       // set up XSLT transformation
 *       TransformerFactory tf = TransformerFactory.newInstance();
 *       Transformer t = tf.newTransformer(new StreamSource("test.xsl"));
 *       
 *       // run transformation
 *       t.transform(new StreamSource("document.xml"),result);
 * 
 *       // obtain the unmarshalled content tree
 *       Object o = result.getResult();
 *    </pre>
 * </blockquote>
 * 
 * <p>
 * The fact that JAXBResult derives from SAXResult is an implementation
 * detail. Thus in general applications are strongly discouraged from
 * accessing methods defined on SAXResult.
 * 
 * <p>
 * In particular it shall never attempt to call the setHandler, 
 * setLexicalHandler, and setSystemId methods.
