I am trying to create a simple Spring webservice which when called returns a file attachement as part of the SOAP response. The Enpoint class is shown below:
And finally the endpoint
@PayloadRoot(namespace="http://ws.mypackage.com", localPart="downloadMessageRequest")
@ResponsePayload
public JAXBElement<DownloadResponseType> invoke(@RequestPayload DownloadMessageRequest req) throws Exception {
DownloadResponseType response = new DownloadResponseType();
DownloadResponseType.PayLoad payload = new DownloadResponseType.PayLoad();
javax.activation.DataHandler dataHandler = new javax.activation.DataHandler(new FileDataSource("c:\\temp\\maven-feather.png"));
payload.setMessagePayLoad(dataHandler);
response.setPayLoad(payload);
return objectFactory.createDownloadMessageResponse(response);
}
I would like the response to include the file as an attachement similar to the following response:
Content-Type: multipart/related; boundary=MIMEBoundary4A7AE55984E7438034;
type="application/xop+xml"; start="<0.09BC7F4BE2E4D3EF1B@apache.org>";
start-info="text/xml; charset=utf-8"
--MIMEBoundary4A7AE55984E7438034
content-type: application/xop+xml; charset=utf-8; type="application/soap+xml;"
content-transfer-encoding: binary
content-id: <0.09BC7F4BE2E4D3EF1B@apache.org>
<?xml version='1.0' encoding='utf-8'?>
<soapenv:Envelope xmlns:soapenv="...."....>

<xop:Include href="cid:1.A91D6D2E3D7AC4D580@apache.org"
xmlns:xop="http://www.w3.org/2004/08/xop/include">
</xop:Include>
........
</soapenv:Envelope>
--MIMEBoundary4A7AE55984E7438034
content-type: application/octet-stream
content-transfer-encoding: binary
content-id: <1.A91D6D2E3D7AC4D580@apache.org>
Binary Data.....
--MIMEBoundary4A7AE55984E7438034--
I have tried to follow the documentation and the sample code in the spring-ws samples and for some reason the output i am getting is always this (i.e. the base64 data is not an attachement.
HTTP/1.1 200 OK
Server: Apache-Coyote/1.1

As you can see, the payload is not an attachment. Here is how i have configured my application:
web.xml
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/app-config.xml
</param-value>
</context-param>

<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<servlet>
<servlet-name>webservice</servlet-name>
<servlet-class>org.springframework.ws.transport.http.MessageDispatcherServlet</servlet-class>
<init-param>

<param-value>/WEB-INF/ws-config.xml</param-value>
</init-param>

The file does get converted to base64binary. The JAXB clases are generated correctly. The Endpoint works but it is not including the file as an attachement. It is including it as part of the XML tag even though i have set mtomEnabled=true.
What am i missing?
ps. Why are the forum code tags not working??
