I downloaded the DocuSignSample and put in my developer credentials and it fails with:
javax.xml.ws.soap.SOAPFaultException: Response was of unexpected text/html ContentType. Incoming portion of HTML stream: <html><head><title>Object moved</title></head><body>
<h2>Object moved to <a href="/API/3.0/Member/Error.aspx?aspxerrorpath=/api/3.0/api.asmx/">here</a>.</h2>
</body></html>
I am using an end point of: "https://demo.docusign.net/api/3.0/api.asmx/";
I am not sure if my issue is the end point or something about my account.
I am see help for other APIS, but not the CredentialSoap used in the code.
