To access the Simplest Possible REST Endpoint from Java, you will have to implement some code:

import javax.ws.rs.client.Client;
import javax.ws.rs.client.ClientBuilder;

  final String URI = "http://localhost:8080/hello-rest/resources/message";
		//...
        Client client = ClientBuilder.newClient();
        String result = client.target(URI).
                request().
                get(String.class);
        assertThat(result, containsString("duke"));

For server-to-server communication no additional dependency is required. If you are using the client as test driver, you will have to declare the dependency to the SPI of you choice e.g.

<dependency>
  <groupId>org.glassfish.jersey.core</groupId>
  <artifactId>jersey-client</artifactId>
  <version>2.21</version>
</dependency>
