I've recently had the same problem as you. I was getting responses with different data structures but all identified by something like:
<item xsi:type="namesp2:SOAPStruct">
You have to tell Apache SOAP about this type in the mapping registry, eg:
mappingRegistry.mapTypes(Constants.NS_URI_SOAP_ENC, new QName(Constants.NS_URI_XML_SOAP, "SOAPStruct"), MyClass.class, null, new BeanSerializer());
This statement would tell apache soap to use a BeanSerializer to deserialize SOAPStruct's into a class of type MyClass.
I found that I had to manipulate the mapping registry for each call to make sure it was set up correctly which was a bit of a pain! I created a call factory which did this manipulation for me based on the call that I asked for and it works quite well.
This link is good for information about creating custome serializers/deserializers:

Hi,
I have been trying to make a Apache Soap Client for my SOAP::Lite web service. However I run into problems with SOAPStructs returned by the service. It seems java cannot deserialize them. I get the following error message java.lang.IllegalArgumentException: No mapping found for '<http://xml.apache.org/xml-soap:SOAPStruct'>http://xml.apache.org/xml-soap:SOAPStruct' using encoding style '<http://schemas.xmlsoap.org/soap/encoding/'>http://schemas.xmlsoap.org/soap/encoding/'. I've tried writting serializers for java but without any success. Can someone please help me with this, I'm going nuts...
