The Apache Wink REST client is a Java-based HTTP client. This client provides convenience methods for using REST services. The JAX-RS specification does not currently define a standard client API. IBM® JAX-RS provides the Apache Wink REST client API as an easy to use, stand-alone client that enables easier integration with stand-alone Java clients. By adding the relevant JAR files to the classpath, you can send requests and receive responses.
You have implemented a JAX-RS client using the Apache Wink Rest client that can issue requests to a JAX-RS application.
