Implementing a JSON representation of a resource with Jackson and JAXB annotated objects
You can process JavaScript Object
Notation (JSON) requests and responses with Java Architecture for XML Binding (JAXB) annotated
objects and Jackson. Jackson is the default JSON processor in WebSphere Application Server.
By default, it is included in the JAX-RS runtime environment so you
do not need to configure Jackson.
Implementing a JSON resource method using JAXB annotated objects with IBM JSON4J
In WebSphere Application
Server Version 8, the default JSON processor to handle serializing
JAXB annotated classes to JSON is Jackson. If you want to use the IBM JSON4J processor from previous
Feature Packs for Web 2.0 instead, you must add a provider class.
Jackson offers more advanced JSON processing.
