How do I use a soap xml based webservice in javascript over a secure https connection?

Question

I want to use a XML SOAP web service in JavaScript to create a Firefox Addon, but the web service I want to use is under a secure https connection.

https://cuotas.uci.cu:443/servicios/v1/InetCuotasWS.wsdl

The soapclient.js library that I downloaded doesn't work with a secure connection. How can I solve this problem? Are there any existing useful JS libraries?

EDIT: This is what is shown in the link

EDIT I used SoapUI as you said, this is the URI https://cuotas.uci.cu/servicios/v1/InetCuotasWS.php?wsdl And SoapMessage is

<soapenv:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:urn="urn:InetCuotasWS">
<soapenv:Header/><soapenv:Body>
<urn:ObtenerCuota soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<usuario xsi:type="xsd:string">dogcalas</usuario>
<clave xsi:type="xsd:string">.*Pepe</clave>
<dominio xsi:type="xsd:string">uci</dominio>
</urn:ObtenerCuota></soapenv:Body></soapenv:Envelope>    

When I send the soap message in Firefox, the alert('ERROR') is shown and Firefox´s firebug addon shows this message.

Error de lectura XML: no se encuentra elemento Ubicación: moz-nullprincipal:{fc98c066-ae21-4b57-b743-83e9519342c7} Número de línea 1, columna 1:

Even using another service, Firefox always shows the same message. Only when I use Internet Explorer 10, the message is sent, but the server response isn´t what I expect:

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"><SOAP-ENV:Body><SOAP-ENV:Fault><faultcode>SOAP-ENV:Client</faultcode>
<faultstring>SoapClient::SoapClient() [&lt;a href='soapclient.soapclient'&gt;soapclient.soapclient&lt;/a&gt;]: 'location' and 'uri' options are required in nonWSDL mode</faultstring></SOAP-ENV:Fault></SOAP-ENV:Body></SOAP-ENV:Envelope>

In IE, if I use another service, the script works.

If you are not concern about Cross-Domain, then you can give this a try... I'll use jQuery as it's way simpler, you would have to convert to your own syntax if you have to as I never did Mozilla Plugins.

Note: you need to get the correct URL for the call, and the correct Soap Message

For this, I would suggest you install SoapUI and connect to the service, you will get all raw information needed to send and receive information

var webServiceURL = 'https://cuotas.uci.cu:443/servicios/v1/InetCuotasWS?op=ObtenerCuota';
var soapMessage = '<soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope"><soap12:Body><ObtenerCuota xmlns="http://tempuri.org/" /></soap12:Body></soap12:Envelope>';

function CallService()
{
    $.ajax({
        url: webServiceURL, 
        type: "POST",
        dataType: "xml", 
        data: soapMessage, 
        contentType: "text/xml; charset=\"utf-8\"",
        success: OnSuccess, 
        error: OnError
    });

    return false;
}

function OnSuccess(data, status)
{
    alert(data.d);
}

function OnError(request, status, error)
{
    alert('error');
}

$(function() {
    jQuery.support.cors = true;
});
