Error ORA-29532 service does not contain port

Question

I used utl_dbws in this simple function:
CREATE OR REPLACE FUNCTION get_meteo (p_int_1 IN VARCHAR2,
p_int_2 IN VARCHAR2)
RETURN VARCHAR2
AS
l_service UTL_DBWS.service;
l_call UTL_DBWS.call;
l_wsdl_url VARCHAR2(32767);
l_namespace VARCHAR2(32767);
l_service_qname UTL_DBWS.qname;
l_port_qname UTL_DBWS.qname;
l_operation_qname UTL_DBWS.qname;
l_xmltype_in SYS.XMLTYPE;
l_xmltype_out SYS.XMLTYPE;
l_return NUMBER;
BEGIN
l_wsdl_url := 'http://www.webservicex.net/globalweather.asmx?WSDL';
l_namespace := 'http://www.webserviceX.NET/';
l_service_qname := UTL_DBWS.to_qname(l_namespace, 'GlobalWeather');
l_port_qname := UTL_DBWS.to_qname(l_namespace, 'GlobalWeatherSoap');
l_operation_qname := UTL_DBWS.to_qname(l_namespace, 'GetWeather');
l_service := UTL_DBWS.create_service (
wsdl_document_location => URIFACTORY.getURI(l_wsdl_url),
service_name => l_service_qname);
l_call := UTL_DBWS.create_call (
service_handle => l_service,
port_name => l_port_qname,
operation_name => l_operation_qname);
l_xmltype_in := SYS.XMLTYPE('<?xml version="1.0" encoding="utf-8"?>
<ws_add xmlns="' || l_namespace || '">
<CountryName>' || p_int_1 || '</CountryName>
<CityName>' || p_int_2 || '</CityName>
</ws_add>');
l_xmltype_out := UTL_DBWS.invoke(call_Handle => l_call,
request => l_xmltype_in);
UTL_DBWS.release_call (call_handle => l_call);
UTL_DBWS.release_service (service_handle => l_service);
l_return := l_xmltype_out.extract('//return/text()').GetStringVal();
RETURN l_return;
END;
SELECT get_meteo('Italy', 'Milan') FROM dual;
When I try to execute it, I get the error:
ORA-29532: chiamata Java terminata a causa di un'eccezione Java non ottenuta:
service: {http://www.webserviceX.NET/}GlobalWeather does not contain port:
{{http://www.webserviceX.NET/}GlobalWeather}GlobalWeatherSoap
ORA-06512: a "SYS.UTL_DBWS", line 266
ORA-06512: a "SYS.GET_METEO", line 29
Why? Where is the mistake?
Here is definition of the webservice:

Answer 1

l_namespace := 'http://www.webserviceX.NET/';
According to the WSDL, the target namespace is :
http://www.webserviceX.NET(no ending slash)
See if it makes a difference.
I don't have UTL_DBWS installed to test, but the webservice works well when invoked via UTL_HTTP :
