> Hi,
> I posted this on the CXF user list without getting a response (except from Aki who supports this);
> We use CXF 3.1.9 together with Camel 2.17.4. We want to enable MTOM on the Camel-CXF producer. To test it I created a simple route using Camel test infrastructure where the producer uses a WSDL with base64 encoded payload parts. But in the log output of CXF I always get a payload like this
> Http-Method: POST
> Content-Type: multipart/related; type="application/xop+xml"; boundary="uuid:2a84a041-d9ce-4caf-a8e1-b4247e1ad6d6"; start="<ro...@cxf.apache.org>"; start-info="text/xml"

> This is not MTOM. The endpoint configuration is
>     <cxf:cxfEndpoint id="clientEndpoint" address="http://localhost:8770/cxf/mtom" bus="ClientBus" wsdlURL="wsdl/mtom_xop.wsdl">
>         <cxf:properties>
>             <entry key="dataFormat" value="PAYLOAD" />
>             <entry key="defaultOperationName" value="testXop" />
>             <entry key="defaultOperationNamespace" value="http://cxf.apache.org/mime"/>
>             <entry key="mtom-enabled" value="true" />
>         </cxf:properties>
>     </cxf:cxfEndpoint>
> Here I even used a WSDL that is used in the CXF MTOM tests. Then I compared the execution of the relevant interceptors in Camel-CXF and CXF and found one difference:
> In AbstractOutDatabindingInterceptor. writeToOutputStream() it is checked that the data binding is implemented by the class org.apache.cxf.jaxb.JAXBDataBinding. That is correct for CXF but Camel-CXF sets in CxfEndpoint the  binding to org.apache.camel.component.cxf.HybridSourceDataBinding which is derived from JAXBDataBinding but of course is a different class. This seems to prevent the completion of the MTOM conversion. I changed the code locally so that now all subclasses are accepted and now the attachment processing gets really called. But now the next problem apears; HybridSourceDataBinding.createWriter() raises an exception:
> java.lang.UnsupportedOperationException: The type java.io.OutputStream is not supported.
> 	at org.apache.camel.component.cxf.HybridSourceDataBinding.createWriter(HybridSourceDataBinding.java:87)
> I guess the method getSupportedWriterFormats of JAXBDataBinding/HybridSourceDataBinding should prevent something like this but in this case it does not work.
> I am also unsure whether the problem is now really in CXF or in Camel-CXF. Therefore please forward it to Camel if the problem is locarted there. 
> Best Regards,
