This document describes how to create a RESTful web service in Eclipse using JAX-RS and WildFly that returns a "Hello World" response. It involves creating a Dynamic Web Project called HelloRest with a JAX-RS endpoint interface and implementation class. The service returns a greeting message that includes a name passed as a query parameter. Client applications are demonstrated including an HTML form, an untyped REST client, and a typed client using JAX-RS and RESTeasy.
