I have a number of TCC scripts that we want to start using with an API integration - but 1st things 1st.

I am Using SoapUI, and trying the example at: https://docs.oracle.com/cloud/latest/taleo/OTWSU/_web_services_getting_started.htm#OTWSUid20110921131114498 to export usernames.

Step 1. Create New Soap Project

Step 2. Initial WSDL links to find service.

Step 3. Create new request :

<query alias="BasicQuery" projectedClass="User"/>
   <projections>
        <projection>
            <field path="UserName"/>
        </projection>
    </projections>
</query>

Step 4. Receive errors
