How to set MTOM options in WSDL-generated stubs?

[Sean Doyle]

I've created a WSDL, run it through WSDL2Java, and I wrote some simple JUnit tests that transfer files over the interface. But - now I'd like to optimize the sending of the files in the client (on the server side MTOM is enabled).

From the example at http://ws.apache.org/axis2/1_0/mtom-guide.html I see that I should set ENABLE_MTOM to true

  ServiceClient serviceClient = new ServiceClient ();

  Options options = new Options();
  options.setTo(targetEPR);
  options.setProperty(Constants.Configuration.ENABLE_MTOM, Constants.VALUE_TRUE);
  serviceClient .setOptions(options);

But - I don't see how to use this object on the stub files generated by WSDL2Java. I can copy the code from the stub (basically the contents of populateAxisService() to return a AxisService object, create a new ServiceClient with the AxisService object, then set the stub's ServiceClient to this new value.

The net result is that everything works fine now but extremely slowly. Sending between two processes on the same machine hits a limit of around 180K/second - over a order of magnitude slower than what I was expecting (I'm sending files that are around 3MB in size). I'm running this on a new Macbook Pro - everything else is quite zippy.

So - if I want speed I think there are two alternatives:
1) Someone will point out the magic combination of API calls to enable MTOM with my generated code - or
2) If this is just a client-side problem - perhaps I code up a  OMElement interface on the client side to set the ENABLE_MTOM parameter to be TRUE?

Other suggestions welcomed :-)

Thanks...
