It looks like the Soap Client is using RPC encoded SOAP messages which
are not supported by Tuscany. Tuscany should really be giving an error
for this, can you raise a JIRA so we can get that fixed. I'm not
familiar with the Soap Client but does it have any config options to
change to not use rpc/encoded, thats a really old style thats not used
much these days.
