Direct access to result document using Apache XML-RPC

Question

I have Apache XML-RPC up and running fine, but I want to see the full XML response document, not just the return value. According to http://ws.apache.org/xmlrpc/client.html in the Transport Factory section, it says:

XmlRpcCommonsTransportFactory -- Another HTTP transport factory, which uses the Jakarta Commons HttpClient. The main advantage over the default factory is, that the Commons HttpClient allows direct access to the result document. This allows a much lower memory profile.

However, I can't find anything about how to directly access the result document. If anyone has done this before, please help me out.
