SOAP server: Response with MTOM attachment does not work

[sburkard]

Use case

SOAP server simulation with Citrus. Client sends request, server responds with an MTOM repsonse with attachment.

Inline attachment works fine

If the attachement is sent as inline attachment, it works

<testcase name="MtomSimulationXml">
    <actions>
        <ws:receive endpoint="soapServerSimulation">
            <message>
                <resource file="testfiles/mtom-request.xml"/>
            </message>
        </ws:receive>
        <ws:send endpoint="soapServerSimulation" mtom-enabled="true">
            <message>
                <resource file="testfiles/mtom-response.xml"/>
            </message>
            <!-- this attachment is correctly delivered to the client -->
            <ws:attachment content-id="myAttachment" content-type="application/octet-stream" mtom-inline="true" encoding-type="base64Binary">
                <ws:resource file="classpath:testfiles/attachment.pdf"/>
            </ws:attachment>
        </ws:send>
    </actions>
</testcase>

Problem

Normal MTOM response (NOT inline) does not work. It is not even a multipart response.

<testcase name="MtomSimulationXml">
    <actions>
        <ws:receive endpoint="soapServerSimulation">
            <message>
                <resource file="testfiles/mtom-request.xml"/>
            </message>
        </ws:receive>
        <ws:send endpoint="soapServerSimulation" mtom-enabled="true">
            <message>
                <resource file="testfiles/mtom-response.xml"/>
            </message>
            <!-- this attachment is NOT delivered to the client -->
            <ws:attachment content-id="myAttachment" content-type="application/octet-stream">
                <ws:resource file="classpath:testfiles/attachment.pdf"/>
            </ws:attachment>
        </ws:send>
    </actions>
</testcase>

Multipart response, but still no attachment

If I add this header to the testcase above, the attachment is still NOT delivered to the client, but it is at least a multipart response.

<header>
    <element name="citrus_http_Content-Type" value="application/xop+xml; charset=utf-8"/>
</header>

Example

I have attached an example project (citrus-mtom.zip) that includes a SoapUI project that acts as a client.

XML testcase with inline attachment works

• Open SoapUI project in SoapUI. There is only 1 test request
• Start XML testcase in IDE as JUnit test
• When the server simulation waits for a request, send the request from SoapUI
• SoapUI gets the response with inline attachement

Java testcase with normal attachment does not work

• Start Java testcase in IDE as JUnit test (or modify the XML testcase according to the examples above)
• When the server simulation waits for a request, send the request from SoapUI
• SoapUI gets the response without attachement
• Look at the RAW response view of the SoapUI test to see multipart structure
