> Hi,

> 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

> 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 is not supported.
> 	at org.apache.camel.component.cxf.HybridSourceDataBinding.createWriter(
> 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.
