I've been trying to use attachments with the Dispatch api, and haven't
been able to make it work. After digging through the code I couldn't see
anywhere that it was even trying to make it work. Is this just not
supported?
Attachments work without any problems on the Provider side.
Here's a sample for Dispatch:
// create and configure the dispatch object with actual service
endpoint address
Service service = Service.create(new
QName("http://cxf.apache.org";, "attachmentService"));
QName portQName = new QName("http://cxf.apache.org";,
"attachmentPort");
service.addPort(portQName, SOAPBinding.SOAP12HTTP_BINDING,
args[0]);
Dispatch<Source> dispatch = service.createDispatch(portQName,
Source.class, Service.Mode.PAYLOAD,
new AddressingFeature(true));
SOAPBinding binding = (SOAPBinding)dispatch.getBinding();
binding.setMTOMEnabled(true);
// configure logging to view messages being exchanged
...
// set attachment to be sent
Map<String, Object> requestContext = dispatch.getRequestContext();
Map<String, DataHandler> attachments = (Map<String,
DataHandler>)requestContext.
get(MessageContext.OUTBOUND_MESSAGE_ATTACHMENTS);
if (attachments == null) {
attachments = new HashMap<String, DataHandler>();
requestContext.put(MessageContext.OUTBOUND_MESSAGE_ATTACHMENTS,
attachments);
}
byte[] bytes = new byte[1024];
for (int i = 0; i < bytes.length; i++) {
bytes[i] = (byte)i;
}
attachments.put("attachment-1", new DataHandler(new
ByteArrayDataSource(bytes)));
// configure the WS-Addressing Action to select operation
...
// execute the request
Source response = dispatch.invoke(new StreamSource(new
ByteArrayInputStream("<test/>".getBytes("UTF-8"))));
System.out.println("Success");
The request gets sent using mime, but without the attachment. Here's the
Provider code that works:
@MTOM(threshold = 0, enabled = true)
@WebServiceProvider(
portName = AttachConstants.PORT_LOCALNAME,
serviceName = AttachConstants.SERVICE_LOCALNAME,
targetNamespace = AttachConstants.SERVICE_NAMESPACE)
@ServiceMode(value = Service.Mode.PAYLOAD)
@BindingType(javax.xml.ws.soap.SOAPBinding.SOAP12HTTP_BINDING)
public class AttachProvider implements Provider<StreamSource>
{
/** Injected context for invocations. */
@Resource
private WebServiceContext serviceContext;
private void setAttachment(DataHandler handler) {
Map<String, DataHandler> attachments = new HashMap<String,
DataHandler>();
attachments.put(AttachConstants.OUT_ATTACH_ID, handler);
serviceContext.getMessageContext().put(MessageContext.OUTBOUND_MESSAGE_ATTACHMENTS,
attachments);
}
public StreamSource invoke(StreamSource request) {
...
byte[] bytes = new byte[AttachConstants.ATTACHMENT_SIZE];
for (int i = 0; i < AttachConstants.ATTACHMENT_SIZE; i++) {
bytes[i] = (byte)i;
}
setAttachment(new DataHandler(new ByteArrayDataSource(bytes)));
Has anyone else gotten Dispatch attachments to work?
Thanks,
- Dennis
