reflect and get the Java method - for each i'th param in the java method - get the first child's i'th child -if the elem has an xsi:type attr then find the deserializer for it - if not found, lookup deser for th i'th param (java type) - error if not found - deserialize & save in an object array - end for

- invoke method and get the return value

- look up serializer for return value based on the value and type

- create response msg and add return value as grand child of
