Create the JAXB Context (Metadata)

The first thing that needs to be done in an JAXB application is to create the JAXBContext. To ensure the EclipseLink JAXB runtime is used see Specifying the EclipseLink JAXB Runtime.

Code Example
Class[] classes = new Class[4];
classes[0] = AddressType.class;
classes[1] = ContactInfo.class;
classes[2] = CustomerType.class;
classes[3] = PhoneNumber.class;
JAXBContext jaxbContext = JAXBContext.newInstance(classes);

Unmarshal the XML Document

JAXB is used to manipulate XML data. The following code demonstrates how to unmarshal an XML document using the statically generated classes see Generating Java Source from an XML Schema.

Code Example
File file = new File("../Resource/bin/Customer-data.xml");
StreamSource source = new StreamSource(file);
Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();
JAXBElement jaxbElement = unmarshaller.unmarshal(source, CustomerType.class);
CustomerType customer = (CustomerType) jaxbElement.getValue();

Modify the Objects

Below is an example of manipulating the objects.

Code Example
PhoneNumber homePhoneNumber = new PhoneNumber();
homePhoneNumber.setValue("(613) 555-3333");

Marshal the Objects

The following code segment demonstrates how to marshal the objects back to XML.

Code Example
Marshaller marshaller = jaxbContext.createMarshaller();
marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);
marshaller.marshal(jaxbElement, System.out);
