soap - mtom does not work, classes are generated by Apache CXF,

Question

It is not possible to optimize the SOAP packet, the data is transmitted. What am I doing wrong?

Generated client classes using JBDS. I looked through a lot of examples it is not possible to implement the ability to transfer files outside the package:

</ SOAP-ENV: Envelope>
---- boundary388.5294117647058824932.470588235294118--
Content-Id: <1.B1150656.EC8A.4B5A.8835.A932E318190B>
Content-Transfer-Encoding: binary
CONTENT-TYPE: application / octet-stream
..........

I change the parameters, but it always turns out like this:

<ns2:AttachmentContentList>
                <ns2:AttachmentContent>
                    <ns2:Id>request.zip</ns2:Id>
                    <ns2:Content>UEsDBBQACAg......

            boolean enabled = true;

Problem found. MTOM stops working if handlerList is added. Please tell me how you can use both handlerList and MTOM at the same time?

        List<Handler> handlerList = binding.getHandlerChain();
        // handlerList.add(new Handler1());
        // handlerList.add(new Handler2());
        handlerList.add(handler1);
        handlerList.add(handler2);
        binding.setHandlerChain(handlerList);
