Example demonstrate how EclipseLink JAXB (MOXy) can map an object model to XML and JSON using the same metadata.

Binding to JSON & XML - Geocode Example

This is the complete source code for the following blog post:

• http://blog.bdoughan.com/2011/08/binding-to-json-xml-geocode-example.html

Summary

In EclipseLink 2.4 the MOXY component includes support for JSON binding. Now you can map the following class:

public class Address {

    @XmlPath("Placemark/ns:AddressDetails/ns:Country/ns:AdministrativeArea/ns:Locality/ns:Thoroughfare/ns:ThoroughfareName/text()")
    private String street;

    @XmlPath("Placemark/ns:AddressDetails/ns:Country/ns:AdministrativeArea/ns:Locality/ns:LocalityName/text()")
    private String city;

    @XmlPath("Placemark/ns:AddressDetails/ns:Country/ns:AdministrativeArea/ns:AdministrativeAreaName/text()")
    private String state;

    @XmlPath("Placemark/ns:AddressDetails/ns:Country/ns:CountryNameCode/text()")
    private String country;

    @XmlPath("Placemark/ns:AddressDetails/ns:Country/ns:AdministrativeArea/ns:Locality/ns:PostalCode/ns:PostalCodeNumber/text()")
    private String postalCode;

}

To the following XML:

<?xml version="1.0" encoding="UTF-8"?>
<Response xmlns="http://earth.google.com/kml/2.0" xmlns:ns="urn:oasis:names:tc:ciq:xsdschema:xAL:2.0">
   <Placemark>
      <ns:AddressDetails>
         <ns:Country>
            <ns:CountryNameCode>US</ns:CountryNameCode>
            <ns:AdministrativeArea>
               <ns:AdministrativeAreaName>CA</ns:AdministrativeAreaName>
               <ns:Locality>
                  <ns:LocalityName>Mountain View</ns:LocalityName>
                  <ns:Thoroughfare>
                     <ns:ThoroughfareName>1600 Amphitheatre Pkwy</ns:ThoroughfareName>
                  </ns:Thoroughfare>
                  <ns:PostalCode>
                     <ns:PostalCodeNumber>94043</ns:PostalCodeNumber>
                  </ns:PostalCode>
               </ns:Locality>
            </ns:AdministrativeArea>
         </ns:Country>
      </ns:AddressDetails>
   </Placemark>
</Response>

And the following JSON:

{
   "Placemark" : {
      "AddressDetails" : {
         "Country" : {
            "CountryNameCode" : "US",
            "AdministrativeArea" : {
               "AdministrativeAreaName" : "CA",
               "Locality" : {
                  "LocalityName" : "Mountain View",
                  "Thoroughfare" : {
                     "ThoroughfareName" : "1600 Amphitheatre Pkwy"
                  },
                  "PostalCode" : {
                     "PostalCodeNumber" : "94043"
                  }
               }
            }
         }
      }
   }}
