Java API for RESTful web services

Java™ API for RESTful web services (JAX-RS), also known as JSR-339, is a programming model that you can use to create to create Representational State Transfer (REST) services quickly.

To develop JAX-RS applications, you must do these tasks:

• Install at least one of the following versions of WebSphere Application Server traditional.
  • WebSphere Application Server Liberty V8.5.5 or later
• Create an application in a project using the JAX-RS template. This template enables the JAX-RS facet, and required components of the Web 2.0 facet. This adds the library, servlet information, and support for JAX-RS annotations processing and JAX-RS quick fixes to your project.

To see how to create a JAX-RS application by using the IBM® JAX-RS implementation, see Tutorial: Creating a JAX-RS web service.
