How to use Webservices in SAP 7.0 SP 17

Question

Hi,
I am having issues calling the webservices in SAP 7.0 SP 17.
I am following the below mentioned tutorial to call a webservice from a portal project (PAR).
http://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/b449e790-0201-0010-1188-ff17840712d3
I have been successful to a point where my websevice needs authentication. I am not sure how to do this.
Here is the code of doContent()
public void doContent(IPortalComponentRequest request, IPortalComponentResponse response)
         try
              logger.infoT("Inside doConent()...");
               UserProfile up = pushUserProfileAttributes();
               logger.infoT("After pushUserProfileAttributes()...");
               ILDAPOperationsService port=(ILDAPOperationsService) PortalRuntime.getRuntimeResources ().getService (ILDAPOperationsService.KEY);
               logger.infoT("After port()...");
               RegisterUserResponse res = port.CreateExternalUserProfile(up);               
               logger.infoT("After res ..user created." + res.getEmailAddress());
         } catch (UserRegistationFailed e){logger.errorT("Error in calling webservice...."+ e.getLocalizedMessage());}
              catch (Exception e1){logger.errorT("Error in calling webservice...."+ e1.getLocalizedMessage());
Its failing at RegisterUserResponse res = port.CreateExternalUserProfile(up);     
and the error I am getting is
Error : Error in calling webservice....com.sap.engine.services.webservices.jaxm.soap.accessor.NestedSOAPException: Problem in server response: [Unauthorized].
Any help with this will be highly appreciated.
Also , if any documentation could be shared.
Looking forward to hear something soon on this.
Thanks,
Shiv

Hi Sumit,
you may move your question to the ABAP for SAP HANA community (http://scn.sap.com/community/abap/hana).
Are you asking about the SAP_BASIS version, or which version do you refer to?
