WebService 4.7 / WAS 620 XSTRING BASE 64

Question

Hi all,
I am working on WebAS 620 and have to call from ABAP side a Webservice via SOAP.
The webservice belongs to a third party tool and is placed on a different server in the internet.
This webservice contains coomlpex parameter. I will include the WSDL to this thread.
Reading the documentation it says that every webservice can be called from ABAP on WAS 602.
(but i don't know how ...)
One of the parameter is a table which can contain many pdf streams. This streams have to be
in BASE64 format
I found an example (SMS) at the forum/blogs, but i didn't found a way to manage this complex
parameter in a WebService call on 620 ...
Do you know if this is possible and how I can do it?
