You are developing a PL/SQL package to perform a web service callout using Oracle UTL_DBWS supplied package. Microsoft's Internet Information Server (IIS) resides as a proxy server between the data server and the application server which hosts the called web service. The IIS has windows integrated security activated which is based on NTLM authentication. If the service is not passed through IIS, the callout works fine. When the service is secured by passing through IIS, the following error message is seen:
java.security.PrivilegedActionException: javax.xml.soap.SOAPException: Message
send failed: HTTPClient.AuthSchemeNotImplException: NTLM
An example invocation:
l_result_XML := SYS.UTL_DBWS.invoke (l_call,evXML_Server);
Since the authentication is based on NTLM, research shows an Oracle Java API - HTTPClient.ntlm:
However there is no documentation stating how to incorporate this using the UTL_DBWS package.
