Webservice Header Issue ( Authentication required )

[WFadloun]

Dears
I am developing client application to consume webservice, the webservice developer sent me the wsdl file and the sample SOAP request , all look fine for me

the issue that when I am trying to call the webservice it returns an error message ( Authentication Required ) but I am sending the user name and the password in the header as expected.

here is the Sample SOAP

<soapenv:Envelope xmlns:fax="[URL unfurl="true"]http://fax.po.ws.apps.oracle.xxdof/"[/URL] xmlns:soapenv="[URL unfurl="true"]http://schemas.xmlsoap.org/soap/envelope/">[/URL]
