EclipseLink/Release/2.4.0/JSONBinding

Object-to-JSON Binding Layer

Overview

New in EclipseLink 2.4 is support for converting objects to and from JSON. This can be useful when creating RESTful services, as JAX-RS services often accept both XML (application/xml) and JSON (application/json) messages.

Same Flexibility as Object-to-XML Mapping

JSON binding is compatible with all existing MOXy extensions. This includes:

• External bindings file
• Dynamic JAXB
• Extensible models

Support both XML and JSON Messages with One Set of Mappings

Both an XML message such as:

<foo xmlns="urn:examle" id="123">
   <bar>Hello World</bar>
</foo>

and a JSON message such as:

{"foo" : {
    "id" : 123,
    "bar : "Hello World"
}}

can be supported by a single object model:

@XmlRootElement(namespace="urn:example")
public class Foo {
 
   @XmlAttribute
   private int id;
 
   @XmlElement(namespace="urn:example")
   private String bar;
 
}
