In my earlier blog entry on Jersey, I used HTTPClient API and curl command line utility as the clients. I had not mentioned about the Jersey Client API. It is part of the Jersey distribution. I would prefer using Jersey Client API as it is modeled around the concepts of JAX-RS spec. Let us quickly re-write our client using the Jersey API and see how easy is to write a client in Java.


import com.sun.jersey.api.client.Client;
import com.sun.jersey.api.client.WebResource;
import restful.impl.jaxb.MovieCollection;
import restful.impl.jaxb.MovieDetails;

import static java.lang.System.out;

public class JerseyClient {
    public static void main(String args[]) {
        Client client = Client.create();
        WebResource r = client.resource("http://localhost:9090/boxoffice/movies");
        MovieCollection movies = r.accept("application/xml").get(MovieCollection.class);
        for (MovieDetails movie : movies.getMovie()) {
            out.println("Title : " + movie.getTitle());
            out.println("Genres : " + movie.getGenres());
            out.println("Directed By : " + movie.getDirectedBy());
            out.println("Rank : " + movie.getRank());
        }        
    }
}

This program will print all the top box office movie details in the console. I will be discussing more about this client API in future posts.
