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.

 * <p>Enables JAXB unmarshalling of a root document containing optimized binary data formats.</p>
 *
 * <p>This API enables an efficient cooperative processing of optimized
 * binary data formats between a JAXB 2.0 implementation and MIME-based package
 * processor (MTOM/XOP and WS-I AP 1.0). JAXB unmarshals the body of a package, delegating the 
 * understanding of the packaging format being used to a MIME-based 
 * package processor that implements this abstract class.</p>
 *
 * <p>This abstract class identifies if a package requires XOP processing, {@link #isXOPPackage()} and provides retrieval of binary content stored as attachments by content-id.</p>
 *
 * <h2>Identifying the content-id, cid, to pass to <code>getAttachment*(String cid)</code></h2>
 * <ul>
 * <li>
 * For XOP processing, the infoset representation of the cid is described 
 * in step 2a in 
 * <a href="http://www.w3.org/TR/2005/REC-xop10-20050125/#interpreting_xop_packages">Section 3.2 Interpreting XOP Packages</a>
 * </li>
 * <li>
 * For WS-I AP 1.0, the cid is identified as an element or attribute of 
 * type <code>ref:swaRef </code> specified in 
 * <a href="http://www.ws-i.org/Profiles/AttachmentsProfile-1.0-2004-08-24.html#Referencing_Attachments_from_the_SOAP_Envelope">Section 4.4 Referencing Attachments from the SOAP Envelope</a>
