CXF File Upload With SOAP MTOM

CXF File Upload With SOAP MTOM shows Implementing a SOAP service for uploading/sending large attachment using MTOM (SOAP Message Transmission Optimization Mechanism)

MTOM is used for encoding binary data in base64Binary and send as binary attachement than keeping it with actual SOAP message. MTOM is approved by WC3 and is a standard. MTOM very useful for transfering binary data such as MS documents, PDF, images etc. MTOM uses XML-binary Optimized Packaging (XOP) packages for transmitting binary data

MTOM is used for sending large attachments using WSDL based services (SOAP).

You can go through following tutorial, in order to use MTOM inside CXF

CXF MTOM File Upload Example

I am creating a simple web service project used for uploading different file formats using CXF MTOM implementation.

The service is using simple POJO (Plain Old Java Object) bean.

Firstly create a Dynamic Web Project (File->New->Dynamic Web Project) named "CXFUpload" according to following screenshot

Create CXF MTOM Project CXF File Upload With SOAP MTOM

Create a FileUploader Object

This is a pojo class used to mapping the binary data, that we are going to upload

package com.student;

import javax.activation.DataHandler;

public class FileUploader {
private String Name;
private String FileType;
private DataHandler Dfile;

public String getName() {
return this.Name;

public void setName(String Name) {
this.Name = Name;

public DataHandler getDfile() {
return this.Dfile;

public void setDfile(DataHandler Dfile) {
this.Dfile = Dfile;

public String getFileType() {
return FileType;

public void setFileType(String FileType) {
this.FileType = FileType;

Create a Service Interface

This service interface will defines which methods of web service, to be invoked by the client

package com.student;

import javax.jws.WebParam;
import javax.jws.WebService;

public interface UploadService {
void uploadFile(@WebParam(name = "file") FileUploader file);

Implement the Service Interface

Here we will implement the service interface created on the previous step

package com.student;

import javax.activation.DataHandler;
import javax.jws.WebService;

@WebService(endpointInterface = "com.student.UploadService", serviceName = "UploadService")
public class UploadServiceImpl implements UploadService {

public void uploadFile(FileUploader Dfile) {

DataHandler handler = Dfile.getDfile();
try {
InputStream is = handler.getInputStream();

         OutputStream os =
new FileOutputStream(new File("C:/uploads/" + Dfile.getName() + "." + Dfile.getFileType()));
byte[] b = new byte[100000];
int bytesRead = 0;
while ((bytesRead = != -1) {
os.write(b, 0, bytesRead);

} catch (IOException e) {



CXF is using Spring internally, Finding classes by spring we need to add service implementation class on "jaxws:endpoint" tag

we also added following line in order to enable the MTOM support inside CXF framework

<entry key="mtom-enabled" value="true" /> 
<beans xmlns=""
	xmlns:xsi="" xmlns:jaxws=""
	<jaxws:endpoint id="uploadfile" implementor="com.student.UploadServiceImpl"
			<entry key="mtom-enabled" value="true" />


Change the web.xml file to find CXF servlet and cxf.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi=""
    xmlns="" xmlns:web=""
    id="WebApp_ID" version="3.0">




Publishing CXF MTOM Web Service

Publish MTOM On Tomcat


You can Find all the deployed JAX-WS/JAX-RS services you need to append 'services' at the end of the URL so URL will become following


Deployed CXF MTOM Web Service

CXF MTOM WebService Running


you can also see CXF MTOM Client in order to run this service
