JAX-WS attachment with MTOM

A complete JAX-WS SOAP-based example to show how to use Message Transmission Optimization Mechanism (MTOM) and XML-Binary Optimized Packaging (XOP) technique to send a binary attachment (image) from server to client and vice verse.

Note
There are ton of articles about what’s MTOM and the benefits of using it (see reference sites below), but it’s lack of complete example to use MTOM in JAX-WS, hope this example can fill in some missing pieces in the whole picture.

Enabling MTOM on server

Enable server to send attachment via MTOM is very easy, just annotate the web service implementation class with javax.xml.ws.soap.MTOM.

1. WebService Endpoint

Here’s a RPC-style web service, published two methods, downloadImage(String name) and uploadImage(Image data), to let user upload or download an image file.

File : ImageServer.java


package com.mkyong.ws;

import java.awt.Image;

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

//Service Endpoint Interface
@WebService
@SOAPBinding(style = Style.RPC)
public interface ImageServer{
	
	//download a image from server
	@WebMethod Image downloadImage(String name);
	
	//update image to server
	@WebMethod String uploadImage(Image data);
	
}

File : ImageServerImpl.java


package com.mkyong.ws;

import java.awt.Image;
import java.io.File;
import java.io.IOException;

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

//Service Implementation Bean
@MTOM
@WebService(endpointInterface = "com.mkyong.ws.ImageServer")
public class ImageServerImpl implements ImageServer{

	@Override
	public Image downloadImage(String name) {
		
		try {
			
			File image = new File("c:\\images\\" + name);
			return ImageIO.read(image);
			
		} catch (IOException e) {
			
			e.printStackTrace();
			return null; 
			
		}
	}

	@Override
	public String uploadImage(Image data) {

		if(data!=null){
			//store somewhere
			return "Upload Successful";
		}
		
		throw new WebServiceException("Upload Failed!");
		
	}

}

File : ImagePublisher.java


package com.mkyong.endpoint;

import javax.xml.ws.Endpoint;
import com.mkyong.ws.ImageServerImpl;

//Endpoint publisher
public class ImagePublisher{
	
    public static void main(String[] args) {
		
	Endpoint.publish("http://localhost:9999/ws/image", new ImageServerImpl());
		
	System.out.println("Server is published!");
	   
    }

}

2. WebService Client

Here’s a web service client, to access the published web service at URL “http://localhost:9999/ws/image“.

File : ImageClient.java


package com.mkyong.client;

import java.awt.Image;
import java.io.File;
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.BindingProvider;
import javax.xml.ws.Service;
import javax.xml.ws.soap.MTOMFeature;
import javax.xml.ws.soap.SOAPBinding;

import com.mkyong.ws.ImageServer;

public class ImageClient{
	
	public static void main(String[] args) throws Exception {
	   
	URL url = new URL("http://localhost:9999/ws/image?wsdl");
        QName qname = new QName("http://ws.mkyong.com/", "ImageServerImplService");

        Service service = Service.create(url, qname);
        ImageServer imageServer = service.getPort(ImageServer.class);
 
        /************  test download  ***************/
        Image image = imageServer.downloadImage("rss.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!");

    }

}

3. HTTP and SOAP traffic

Here’s the HTTP and SOAP traffic generated by the client, captured by traffic monitoring tool.

P.S The first wsdl request is omitted to save space.
Client send request :


POST /ws/image HTTP/1.1
SOAPAction: ""
Accept: text/xml, multipart/related, text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2
Content-Type: text/xml; charset=utf-8

Enabling MTOM on client

Enable client to send attachment via MTOM to server is required some extra efforts, see following example :


//codes enable MTOM in client
BindingProvider bp = (BindingProvider) imageServer;
SOAPBinding binding = (SOAPBinding) bp.getBinding();
binding.setMTOMEnabled(true);

1. WebService Client

Here’s a webservice client to send an image file to published endpoint above (http://localhost:8888/ws/image) via MTOM.

File : ImageClient.java


package com.mkyong.client;

import java.awt.Image;
import java.io.File;
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.BindingProvider;
import javax.xml.ws.Service;
import javax.xml.ws.soap.MTOMFeature;
import javax.xml.ws.soap.SOAPBinding;

import com.mkyong.ws.ImageServer;

public class ImageClient{
	
	public static void main(String[] args) throws Exception {
	   
	URL url = new URL("http://localhost:8888/ws/image?wsdl");
        QName qname = new QName("http://ws.mkyong.com/", "ImageServerImplService");

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

        /************  test upload ****************/
        Image imgUpload = ImageIO.read(new File("c:\\images\\rss.png"));
        
        //enable MTOM in client
        BindingProvider bp = (BindingProvider) imageServer;
        SOAPBinding binding = (SOAPBinding) bp.getBinding();
        binding.setMTOMEnabled(true);
   
        String status = imageServer.uploadImage(imgUpload);
        System.out.println("imageServer.uploadImage() : " + status);
        
    }

}

I am new to SOAP webservice. I downloaded your code & used but i got an error at ” ImageServer imageServer = service.getPort(ImageServer.class);” saying nullpointerException. I am using Eclipse(helios) with tomcat 6 .I have no knowledge of xml too.

Dear,
The main problem is webclient is another machine so it is unable to find ImageServer class.then how it will work.

mkyoung,

Thank you for taking the time to put this tutorial together. You saved us many more hours of banging our heads against the wall trying to figure out how to correctly enable MTOM on the client to send a large file up to the server.

Thanks,

Thanks for your article. It is really helpful. I created my Mtom project successfully but I am facing with another problem about Mtom&soap signature. While trying to verify soap signature with SoapHandler, Soaphandler tries to keep all message and destroys Mtom optimization. Then it switches the attachment to base64 encoded. Do you know anything about this? How can i verify the soap message properly without destroy Mtom optimization?

Thanks

In the case of upload, the client is using the java.awt.Image object and pass it to the remote method call uploadImage(). How does non-java consumers call this method when they dont have java.awt.Image library?

This is some great stuff. Here’s what else I did with it. I wrote an RPC web service. I wanted to use encryption but the algorithms introduce invalid XML characters. You couldn’t transfer the data due to XMLStreamException(s). I used your example to transfer the encrypted data as byte[]. I was able to use the encryption! Next I wrote up some code to do serialized Object transfers. I uploaded a Customer object, changed the name using setName(String s) and then sent the object back down. The name changed! I have a question public ImageServer getImageServerImplPort(WebServiceFeature… features) What’s up with the… Read more »

Although the response has a binary attachment, there is no xop tag. Instead, there is the ascii base64 attachment inside a “return” tag and “Content-Type: text/xml; charset=utf-8”.

It works fine if I use soapUI and force MTOM, but I can’t make it with a dynamic proxy, although it returns true for SOAPBinding.isMTOMEnabled().
