Web Services - Java client

Robert Mac asked some time ago for Java client for my old post here: Web Services in Ruby, Python and Java. So here it is (sorry for the delay). Simplest possible solution, no jars or IDE needed. Just plain Java 6 JDK.

First we have to generate proxy classes for our Web Service (you need to pass WSDL location, as URL or path to file):

wsimport http://localhost:8080/WSServer/Music?wsdl

wsimport is in /bin folder in your JDK.

Now let’s use them:

public class WSClient {

    public static void main(String[] args) {
        Music music = new Music();
        String[] artists = music.listArtists();
        for (String artist : artists) {
            System.out.println(artist);
            Song[] songs = music.listSongs(artist);
            for (Song song : songs) {
                System.out.format("\t%s : %s : %d%s\n", new Object[]{song.getFileName(), song.getArtist(), song.getSize(), "MB"});
            }
        }
    }
}

Now compile it and execute with classes generated by wsimport in classpath.
This is all. Simple, isn’t it?
