WSDL.Proxy newbie question

[dresserd at gouldacademy.org]

Hello,

I am new to implementing and consuming web services with Python.  I
have had
some success setting up a simple SOAPServer and connecting to it and
also using
some of the simpler (one parameter) web services available from
xmethods.org.
I
am currently stuck trying to use a simple hashing service that requires
more
than one parameter to be passed.  I have done a lot of searching and
tried
passing the parameters in many ways.  I think I am stuck on what type
of data
structure to pass the service.

here's the xmethod service profile
http://www.xmethods.net/ve2/ViewListing.po;jsessionid=zbLKBgtAiSjIS-KAclxRipnP(QHyMHiRM)?key=uuid:FD460436-81BF-86BD-F252-2AB6C00B624C

Below is an example attempt.  Thanks in advance for any suggestions.

>>> server.soapproxy.config.dumpSOAPOut =1
>>> server.soapproxy.config.dumpSOAPIn =1
>>> server.debug = 1
>>> server.HashString({'Str':'test','HashType':'MD5'})
