JAXB API 2.2.12 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-2.2.12.jar is the JAR file for the JAXB API 2.2 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.Source} implementation
 * that marshals a JAXB-generated 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 marshal a document
 * for transformation by XSLT.
 * 
 * <blockquote>
 *    <pre>
 *       MyObject o = // get JAXB content tree
 *       
 *       // jaxbContext is a JAXBContext object from which 'o' is created.
 *       JAXBSource source = new JAXBSource( jaxbContext, o );
 *       
 *       // set up XSLT transformation
 *       TransformerFactory tf = TransformerFactory.newInstance();
 *       Transformer t = tf.newTransformer(new StreamSource("test.xsl"));
 *       
 *       // run transformation
 *       t.transform(source,new StreamResult(System.out));
 *    </pre>
 * </blockquote>
 * 
 * <p>
 * The fact that JAXBSource derives from SAXSource is an implementation
 * detail. Thus in general applications are strongly discouraged from
 * accessing methods defined on SAXSource. In particular,
 * the setXMLReader and setInputSource methods shall never be called.
 * The XMLReader object obtained by the getXMLReader method shall
 * be used only for parsing the InputSource object returned by
 * the getInputSource method.
 * 
 * <p>
 * Similarly the InputSource object obtained by the getInputSource
 * method shall be used only for being parsed by the XMLReader object
 * returned by the getXMLReader.
