consuming a sharepoint webservice from PL SQL - To transfer a file from UNIX to Sharepoint

 Hi all,

    I am trying to transfer a file available in UNIX server to Sharepoint. I have chosen to use the built-in webservice provided by Microsoft sharepoint to upload files. This webservice will be available in the location 'http://<sharepoint-location>/_vti_bin/Copy.asmx'. where, <sharepoint-location> is the sharepoint address.

   I have created a simple anonymous block that calls this webservice. When i run this block, ORA-29532 error occurs. The below is the entire error message.

ORA-29532: Java call terminated by uncaught Java exception: HTTP transport error:
javax.xml.soap.SOAPException: java.security.PrivilegedActionException: javax.xml.soap.SOAPException:
Message send failed: HTTPClient.AuthSchemeNotImplException: NTLM
