Runtime error wihle calling a webservice

Question

Hi all,
I am trying a portal application which uses an external webservice . I have created a portal service from the webservice and then used it in a portal component     after excuting  i am getting the following exception at run time .
com.sap.engine.services.webservices.jaxm.soap.accessor.NestedSOAPException: Problem in server response: Proxy Authentication Required.
I have given the proxy settings in the com.sap.portal.ivs.httpservice  in the portal and also
defined a proxy server in the Visual Administrator under Services -> Webservice Container -> HTTP Proxy Server
I am calling service in the following manner.
IPortalRuntimeResources runtime = PortalRuntime.getRuntimeResources();
IServiceservice = runtime.getService(IWS_P_Service.KEY);
   IWS_P_Service ws_service = (IWS_P_Service)service;
    Volumes from = new Volumes(Volumes.VOLUMES_KILOLITER_VALUE);
    Volumes to = new Volumes(Volumes.VOLUMES_LITER_VALUE);
    ChangeVolumeUnit cvu = new ChangeVolumeUnit(1200,from,to);
    // working upto here
     response.write("working");
     ChangeVolumeUnitResponse cvu_res = ws_service.ChangeVolumeUnit(cvu);
     double result = cvu_res.getChangeVolumeUnitResult();
     response.write(result+"");
The program is executing till "Working"
If any body has any solutions please post.
