Unsupported policies issue while calling Web service.

Hi All,

I'm trying to call a web service using the 'Call Web Service' smart service. However, when I paste the WSDL URL, I receive the following warning. As a result, I'm unable to select the Service and Endpoint options. Is there a solution to configure the webservice without modifying the WSDL structure?

Warning: 'The endpoint BasicHttpBinding_AAA contains a reference to an ExactlyOne policy operator which does not contain a supported policy alternative. That endpoint is not available for selection. The unsupported policies are [[alternative 1 : SignedSupportingTokens, Wss10]]. (APNX-2-4041-007).'

Hi Sharat,

1. In the WDSL URL, do not enter the dynamic URL which gets generated in run time, you can use "use dynamic wsdl url" check box.

2. If you are connecting using a proxy server you have to enable settings in admin console.

3. Below page has list which are not supported.

See if below documentation helps, docs.appian.com/.../Call_Web_Service_Smart_Service.html

Hello [mention:37a936c53217469e86396495d68d179f:e9ed411860ed4f2ba0265705b8793d05] 
You can ask server-side to disable security policies SignedSupportingTokens with the Wss10 standard.
SignedSupportingTokens authentication scheme is not supported


Still you can think of this option suggested by Appian.
