The Java EE 7 Tutorial
19.5 JSON in Java EE RESTful Web Services
This section explains how the Java API for JSON Processing is related to other Java EE packages that provide JSON support for RESTful web services. See Chapter 29, "Building RESTful Web Services with JAX-RS," for more information on RESTful web services.
Jersey, the reference implementation for JAX-RS (JSR 311) included in GlassFish Server, provides support for binding JSON data from RESTful resource methods to Java objects using JAXB, as described in Using JAX-RS with JAXB in Chapter 31, "JAX-RS: Advanced Topics and an Example". However, JSON support is not part of JAX-RS (JSR 311) or JAXB (JSR 222), so that procedure may not work for Java EE implementations other than GlassFish Server.
The Java API for JSON Processing (JSR 353) does not explicitly support JSON binding in Java. A future JSR (JSON Binding) that is similar to JAXB for XML is under consideration for a future release of Java EE.
You can still use the Java API for JSON Processing with JAX-RS resource methods. For more information, see the sample code for JSON Processing included with the Java EE 7 SDK.
