Claudio, I cannot speak for these other services, but you can grab my example WSDL file (one for openacs):
http://junom.com/ws/openacs/?WSDL
From my experience the wsdlpull client more correctly constructs SOAP messages. It doesn't know how to verify restrictions based upon patterns (regexp), but it does verify enumerations.
On the command to invoke stockQuoter, I guess you mean what SOAP message to send? In the stockquoter/www directory, there should be a post.tcl file, which probably needs to be edited so it sends to the correct address. Otherwise what you are asking for is a client, and wsdlpull looks like the easiest to use.
Otherwise, move the stockquoter procs to another file under pageroot and use the <ws>* API.
