Unmarshalling an XML document

In this section, we shall unmarshal an XML document using the JAXB API and the Java classes generated by compiling the example XML schema. A prerequisite for unmarshalling is that the XML document should conform to the XML schema from which the binding classes are generated. The XML document that we shall unmarshal is the same that is marshalled in the previous section. Create a Java application, JAXBUnMarshaller.java, in JDeveloper project JAXB similar to the JAXBMarshaller application. In the JAXBUnMarshaller class import the JAXB API package. As JAXBUnMarshaller.java is created in the same package as the binding classes, the binding classes do not need to be imported.

import javax.xml.bind.*;

Create a JAXBContext object using static method newInstance(String contextPath). ContextPath is a colon-separated list of packages that contain the schema-derived binding classes.

JAXBContext jaxbContext=JAXBContext.newInstance("jaxb");
