XML Parsing With JAXB

I want to parse the following xml, i tried with JAXB as follows,

public class XMLParsing {

    private static Fields       fields       = null;
    private static JAXBContext  context      = null;
    private static Unmarshaller unmarshaller = null;

    public static void main(String[] args) {

        fields = process();

        System.out.println("Field List : "+fields.getFieldList());

    }

    public static Fields process(){

        try{
            context = JAXBContext.newInstance(Fields.class);
            unmarshaller = context.createUnmarshaller();
            fields = (Fields) unmarshaller.unmarshal(new File("/media/rakesh/WorkZ/test.xml"));
        } catch(Exception e){
            e.printStackTrace();
        } finally{
            context      = null;
            unmarshaller = null;
        }

        return fields;

    }

}

XML File :

<?xml version="1.0" encoding="UTF-8"?>

   <Field Name="list">

Fields.class

@XmlRootElement(name="Fields")
public class Fields {

    private List<Field> fieldList;

    /**
     * @return the fieldList
     */
    public List<Field> getFieldList() {
        return fieldList;
    }

    /**
     * @param fieldList the fieldList to set
     */
    @XmlElement(name="FieldList")
    public void setFieldList(List<Field> fieldList) {
        this.fieldList = fieldList;
    }

}

I think the problem is with the Fields class. Can any please suggest the correct way to parse the xml.
