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>
 * The javaType binding declaration can be used to customize the binding of 
 * an XML schema datatype to a Java datatype. Customizations can involve 
 * writing a parse and print method for parsing and printing lexical 
 * representations of a XML schema datatype respectively. However, writing 
 * parse and print methods requires knowledge of the lexical representations ( 
 * <a href="http://www.w3.org/TR/xmlschema-2/"> XML Schema Part2: Datatypes 
 * specification </a>) and hence may be difficult to write. 
 * </p>
 * <p>
 * This class makes it easier to write parse and print methods. It defines
 * static parse and print methods that provide access to a JAXB provider's 
 * implementation of parse and print methods. These methods are invoked by 
 * custom parse and print methods. For example, the binding of xsd:dateTime 
 * to a long can be customized using parse and print methods as follows:
 * <blockquote>
 *    <pre>
 *    // Customized parse method 
 *    public long myParseCal( String dateTimeString ) {
 *        java.util.Calendar cal = DatatypeConverter.parseDateTime(dateTimeString);
 *        long longval = convert_calendar_to_long(cal); //application specific
 *        return longval;
 *    }
 *     
 *    // Customized print method
 *    public String myPrintCal( Long longval ) {
 *        java.util.Calendar cal = convert_long_to_calendar(longval) ; //application specific
 *        String dateTimeString = DatatypeConverter.printDateTime(cal);
 *        return dateTimeString;
 *    }
 *    </pre>
 * </blockquote>
 * <p>
 * There is a static parse and print method corresponding to each parse and 
 * print method respectively in the {@link DatatypeConverterInterface 
 * DatatypeConverterInterface}. 
 * <p>
 * The static methods defined in the class can also be used to specify
 * a parse or a print method in a javaType binding declaration.
 * </p>
 * <p>
 * JAXB Providers are required to call the 
 * {@link #setDatatypeConverter(DatatypeConverterInterface) 
 * setDatatypeConverter} api at some point before the first marshal or unmarshal 
 * operation (perhaps during the call to JAXBContext.newInstance).  This step is 
 * necessary to configure the converter that should be used to perform the 
 * print and parse functionality.  
 * </p>
 * 
 * <p>
 * A print method for a XML schema datatype can output any lexical 
 * representation that is valid with respect to the XML schema datatype.
 * If an error is encountered during conversion, then an IllegalArgumentException,
 * or a subclass of IllegalArgumentException must be thrown by the method.
 * </p>
