Python & SOAP

[annaiak]

I trying to run some implementation of SOAP in Python. Iam using ZSI, 
but iam little bit lost. I downloaded the official documentation, but 
iam still not able to understand relations between objects (soapwriter, 
typecode). Everything i can, is send a simple string via return value of 
server function to client request. I need more. Some examples would be 
useful for me. Searching with google had no results 
(http://www-128.ibm.com/developerworks/webservices/library/ws-pyth9/). I 
need sending data inside function body. I need send contents /etc/passwd 
or contents postrgresql table.
I'll be glad if you have some experience or at least some links.
