[GoogleCodeExporter]

What steps will reproduce the problem?
1. Call web service which returns MTOM response

What is the expected output? What do you see instead?
Response should be read correctly. Error appears instead.

What version of the product are you using? On what operating system?
Android 2.3.4, Samsung Galaxy GIO S5660 (but it doesn't matter)

You need to provide more detail at least. Ideally a potential example app and a 
patch that fixes it..

It doesn't matter what web service I call. The key is that the web service 
returns MTOM response. ksoap2 says that the response is incorrect. I have no 
fix for that, but I have an idea. There could be one property which says what 
kind of response is expected. The response should be parsed in the way 
specified by the property.

You could debug this with the source code from github and see.

Here is stacktrace

And here is the code that creates the output above:
try {
 ht.call("obtainExtraProjectIds", envelope);
 if (envelope.getResponse() == null) {
  throw new Exception("Communication Error.");
 } else {
  returnMSG = "else";
 }
} catch (Exception ex) {
 if (returnMSG == null) {
  returnMSG = getStackTrace(ex); // getStackTrace converts ex.getStackTrace() to String
  System.out.println(returnMSG); // THE OUTPUT - STACKTRACE
 }
}

And here is the response (sniffed using wireshark):

That seems a problem deep down in kxml2. I dont have time or resources to debug 
but the source for it all is on github so feel free to take a stab at it.

This is not xml parser problem. The problem is that Http Transport class does 
not parse MTOM message properly. It seems that HttpTransportSE.Parse passes 
body of the response directly to kxml2 while the correct way would be to parse 
MTOM message and pass extracted SOAP envelop to the parser.

Ok.. fair enough. I know nothing about MTOM so I guess I looked in the wrong 
place. If you know more it would be great if you could implement your 
suggestion and send a pull request with any required fixes/enhancements.

I am working on implementing MTOM on KSOAP2. 

Basically the content-type for MTOM is multipart/related instead of xml. So the 
first thing is to identify by this if it is a MTOM response,then get the 
boundary (Which is the part separator) to parse individually each part, one of 
those is the XML soap response (the one with content-type containing xml) and 
the rest of the parts are the MTOM content that needs to be saved to disk for 
future reference

I'm a main developer in http://easywsdl.com. We are working on MTOM 
implementation for ksoap2 library. We are going to publish our extensions to 
ksoap2 as a separate library but for now if you need MTOM transfer, you will 
find a working solution in http://easywsdl.com.

Feel free to provide the MTOM implementation as a pull request to this project 
as well to make things easier for users. Provided of course this works for you 
in terms of project flow and license.

Is this issued solved ? I get the same problem here. I already download the 
newest version 3.4 and still get the error. Or maybe I'm missing some new 
function ? thanks..

The project is migrating to github. If you believe this issue is still valid 
and should be tracked please file a new issue at
