NuSOAP and SSL?

I'm trying to connect to a webservice using WSDL. The following code works perfectly: require_once('nusoap.php'); $url_wsdl = "http://www.my.server:8080/axis/services/aservice?wsdl"; $parameters = array($param1, $param2, $param3); $soapclient = new soapclient($url_wsdl,'wsdl'); $res = $soapclient->call('serveme', $parameters); ..$res is then parsed and printed to a page. However, once I change to using SSL via: $url_wsdl = "https://www.my.server:8443/axis/services/aservice?wsdl"; ..nothing is printed. It is as if the call never goes through. After hunting around for some information, I installed cURL with SSL on the client machine. It still does not work, though. Can anyone help? I've been stuck on this for almost 3 days now.
