Hi;

  ws_call         UTL_DBWS.CALL;
  ws_wsdl_url     uritype;
  ws_request_xml  xmltype;
  ws_response_xml xmltype;
BEGIN
  ws_wsdl_url     := urifactory.getUri(url => 'http://10.85.249.85:1112/ws?WSDL');
  ws_service      := utl_dbws.create_service(ws_wsdl_url, NULL);
  ws_call         := utl_dbws.create_call(ws_service);

I worked on it. I changed some of my code but I am getting an error again:
DECLARE
  ws_service      UTL_DBWS.service;
  ws_call         UTL_DBWS.CALL;
  ws_wsdl_url     uritype;
  ws_request_xml  xmltype;
  ws_response_xml xmltype;
BEGIN
  ws_wsdl_url     := urifactory.getUri(url => 'http://10.85.249.85:1112/ws?WSDL');
  ws_service      := utl_dbws.create_service(ws_wsdl_url, 'WS');
  ws_call         := utl_dbws.create_call(ws_service, NULL, 'process');
  utl_dbws.set_property(ws_call, 'OPERATION_STYLE', 'DOCUMENT');
  ws_request_xml  := xmltype('<ns0:WSMessage xmlns:ns0="http://10.85.249.85/schemas"><ns0:WSHeader ACTION="UPDATE"/><ns0:WSPayload><ns0:Attribute name="123456" value="test"/></ns0:WSPayload></ns0:WSMessage>');
  ws_response_xml := utl_dbws.invoke(ws_call, ws_request_xml);
  utl_dbws.release_call(ws_call);
  utl_dbws.release_service(ws_service);
  dbms_output.put_line(ws_response_xml.getstringval);
END;
