see this article. http://www.perfectxml.com/articles/xml/soapguide.asp Apache SOAP doesn't like a response without xsi:type. This is a known interop issue between Apache client and MS server. Also an Integer serializer (and a lot others) is built in SOAPMappingRegistry for SOAP encoding style. You don't have to set your IntSerializer. Hope this helps.

I am using the Java client below, which calls a method (test_AddThem) to add two numbers and return the result. This result is always a '0' (zero). I have another version of this method which adds the xsi:type attribute to each element in the returned XML, since Microsoft's server does not normally do this. This method works fine and returns the correct result. I am adding to the mapping registry the deserializer to deserialize the 'test_AddThemResponse' response element as an Integer yet I still get zero as the result. I have been trying to find my bug for about 4 hours now with no luck. Could someone help me out? I will be very grateful. Thanks.
