Calling a Webservice with Savon

# testing the webservice with soapUI works fine using :
# <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:tem="http://tempuri.org/">
#   <soapenv:Header/>
#   <soapenv:Body>
#      <tem:GetAllUsers/>
#   </soapenv:Body>
# </soapenv:Envelope>
