10.19. Attachments

JBoss-WS4EE relied on a deprecated attachments technology called SwA (SOAP with Attachments). SwA required soap/encoding which is disallowed by the WS-I Basic Profile. JBossWS provides support for WS-I AP 1.0, and MTOM instead.

10.19.1. MTOM/XOP

This section describes Message Transmission Optimization Mechanism (MTOM) and XML-binary Optimized Packaging (XOP), a means of more efficiently serializing XML Infosets that have certain types of content. The related specifications are

The above table shows a list of supported endpoint parameter types. The recommended approach is to use the javax.activation.DataHandler classes to represent binary data as service endpoint parameters.

Note

Microsoft endpoints tend to send any data as application/octet-stream. The only Java type that can easily cope with this ambiguity is javax.activation.DataHandler

10.19.1.2. Enabling MTOM per endpoint

On the server side MTOM processing is enabled through the @BindingType annotation. JBossWS does handle SOAP1.1 and SOAP1.2. Both come with or without MTOM flavors:
MTOM enabled service implementations 
package org.jboss.test.ws.jaxws.samples.xop.doclit;
  
import javax.ejb.Remote;
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;
import javax.xml.ws.BindingType;
  
@Remote
@WebService(targetNamespace = "http://org.jboss.ws/xop/doclit")
@SOAPBinding(style = SOAPBinding.Style.DOCUMENT, parameterStyle = SOAPBinding.ParameterStyle.BARE)
@BindingType(value="http://schemas.xmlsoap.org/wsdl/soap/http?mtom=true")                         (1)
public interface MTOMEndpoint

  1. The MTOM enabled SOAP 1.1 binding ID
MTOM enabled clients
Web service clients can use the same approach described above or rely on the Binding API to enable MTOM (Excerpt taken from the org.jboss.test.ws.jaxws.samples.xop.doclit.XOPTestCase): 
...
Service service = Service.create(wsdlURL, serviceName);
port = service.getPort(MTOMEndpoint.class);
  
// enable MTOM
binding = (SOAPBinding)((BindingProvider)port).getBinding();
binding.setMTOMEnabled(true);

Use the JBossWS configuration templates to setup deployment defaults.
