If you didn't notice, this version allows you to develop plugins (with Java) that can be imported into your ORDS instance, and provide extended functionality. You want to refer to the Oracle REST Data Services Plugin API, located here:  http://download.oracle.com/otndocs/java/javadocs/3.0/plugin-api/index.html , which itself includes a couple of nice documents: Getting started guide Developer guide This post just re-iterates a lot of what has already been covered in the getting started guide, with a focus on using IntelliJ IDEA. Setting the project up in IntelliJ IDEA So the first step is to set up a new project.
