title: Use ssl certificate in SOAP client
body: <p>I am creating a SOAP client to communicate with a webservice. 
  I have a .pfx certificate in order to communicate with the webservice but I'm not sure how to use it.</p>
  
  <p>If I understand correctly, I need to load the certificate into the jvm. This is what I have right now:</p>
  
  <pre><code>System.setProperty("javax.net.ssl.keyStore", "path/to/cert.pfx");
  System.setProperty("javax.net.ssl.keyStorePassword", "qwerty123");
  System.setProperty("javax.net.ssl.keyStoreType", "PKCS12");
  
  OrderResponseType response = locator.getRpServiceSoapPort().authenticate(authRequest);
  </code></pre>
  
  <p>However, running this code gives me the following error:</p>
  
  <pre><code>Exception in thread "main" AxisFault
