Pada tutorial sebelumnya saya memposting cara menggunakan JAX-WS, pada kesempatan kali ini saya akan memposting bagaimana membuat web service dengan attachment dengan menggunakan Transmission Optimization Mechanism (MTOM). Lets begin…

1. Create Web Service

Class = ImageServer.java

package com.yudi.ws;

import java.awt.Image;

import javax.jws.WebMethod;
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;
import javax.jws.soap.SOAPBinding.Style;

@WebService
@SOAPBinding(style = Style.RPC)
public interface ImageServer {

@WebMethod Image downloadImage(String name);
@WebMethod String uploadImage(Image data, String name, int param1, int param2, String operator);

}

Class = ImageServerImpl.java

package com.yudi.impl;

import java.awt.Image;
import java.awt.image.BufferedImage;
import java.awt.image.RenderedImage;
import java.io.File;
import java.io.IOException;
import java.net.URL;

import javax.imageio.ImageIO;
import javax.jws.WebMethod;
import javax.jws.WebService;
import javax.xml.ws.WebServiceException;
import javax.xml.ws.soap.MTOM;

import com.yudi.ws.ImageServer;

@MTOM
@WebService(endpointInterface = "com.yudi.ws.ImageServer")
public class ImageServerImpl implements ImageServer {

final static String PATH = "/home/yudi/Pictures/";

@WebMethod
public Image downloadImage(String name) {
// TODO Auto-generated method stub
try {

File image = new File("/home/yudi/Pictures/" + name);
return ImageIO.read(image);

} catch (IOException e) {

e.printStackTrace();
return null;

}
 }

@WebMethod
public String uploadImage(Image image, String name, int param1, int param2, String operator) {
// TODO Auto-generated method stub
int hasil =0;
if (image != null) {
try {
File imageFile = new File(PATH + name);
ImageIO.write((RenderedImage) image, "png", imageFile);

if("+".equals(operator)){
hasil = param1 + param2;
}else if("*".equals(operator)){
hasil = param1 * param2;
} else {
hasil = param1 - param2;
}

} catch (IOException e) {
e.printStackTrace();
throw new WebServiceException("Upload Failed");
}
return "Upload Successful "+String.valueOf(hasil);

 }

throw new WebServiceException("no data to upload!");

}

}

Class = ImagePublisher.java

package com.yudi.publish;

import javax.xml.ws.Endpoint;

import com.yudi.impl.ImageServerImpl;
public class ImagePublisher {

 public static void main(String[] args) {

 Endpoint.publish("http://localhost:9999/ws/image", new ImageServerImpl());
 System.out.println("Publish");
 }
}

Jalankan ImagePublisher.java untuk mem-publish web service yang telah kita buat tadi.

2. Web Service Client

Class = Main.java

package com.yudi.main;

import java.awt.Image;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import java.net.URL;

import javax.imageio.ImageIO;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.xml.namespace.QName;
import javax.xml.ws.Service;

import com.yudi.ws.ImageServer;

public class Main {

public static void main(String[] args) {

/************ test upload ***************/
 try {
 URL url = new URL("http://localhost:9999/ws/image?wsdl");
 QName qname = new QName("http://impl.yudi.com/",
 "ImageServerImplService");

Service service = Service.create(url, qname);
 ImageServer imageServer = service.getPort(ImageServer.class);

File imageFile = new File("/home/yudi/Music/bg.png");
 Image imageUi = null;

 imageUi = ImageIO.read(imageFile);

 imageServer.uploadImage((BufferedImage) imageUi,"bg_upload.png", 5, 6, "*");
 System.out.println("Upload Successful");

/************ test download ***************/
 Image image = imageServer.downloadImage("bg_upload.png");
 //display it in frame
 JFrame frame = new JFrame();
 frame.setSize(300, 300);
 JLabel label = new JLabel(new ImageIcon(image));
 frame.add(label);
 frame.setVisible(true);

 System.out.println("imageServer.downloadImage() : Download Successful!");

 } catch (IOException e) {
 // TODO Auto-generated catch block
 e.printStackTrace();
 }

}
}

Selesai, silahkan di test, tolong di komentary
