title: soapui soap digital signature
body: <p>I need to digitally sign a soap message in a client. A PEM file with both private key and certificate has been given to me. I thought to test with SoapUI. </p>
  
  <p>Configuration for signature is done OK in Outgoing WS Security configuration - see the picture, as well,  pem is added OK in Keystore/Certificate tab, but the soap message sent to a service is not signed. 
  Does anybody know how to solve this problem?</p>
