title: Using pysimplesoap to call ladonize SOAP example. Getting the syntax right
body: <p>I'm trying to call the calculator example from 
  <a href="http://ladonize.org/python-demos/" rel="nofollow">ladonize.org</a> using this code.</p>
  
  <p>I managed to get pysimplesoap to work with other external soap services and am trying to roll out my own soap service using ladon / python 2.7</p>
  
  <p>The SOAP service works when imported into Visual Studio 2008 under Windows.
  For python I can't get the syntax for the request right.
  The sample web service accepts two numbers a &amp; b and returns the added value as a result </p>
  
  <p>This is the code I have</p>
  
  <pre><code>from pysimplesoap.client import SoapClient
  
  client = SoapClient(wsdl='http://ladonize.org/python-demos/Calculator/soap/description',
  location='http://ladonize.org/python-demos/Calculator/soap/description', cacert=None)
  
  response=client.add(paramters={"a":"1","b":"2"})
  print (response)
  </code></pre>
  
  <p>This call is not working.
  I get the error "AttributeError: Tag not found: Body (No elements found)"</p>
  
  <p>The call I want to make it is this function</p>
  
  <pre><code>    &lt;portType name="CalculatorPortType"&gt;
  &lt;operation name="add"&gt;   
  &lt;documentation&gt;Add two integers together and return the result &lt;/documentation&gt;
  &lt;input message="tns:add"/&gt;
  &lt;output
      message="tns:addResponse"/&gt;
  &lt;/operation&gt;
  &lt;/portType&gt;
  </code></pre>
  
  <p>Full description is <a href="http://ladonize.org/python-demos/Calculator/soap/description" rel="nofollow">here</a> </p>
  
  <p>Any tips on what to look for in the description to get the syntax right?</p>
