Running jre1.6.0_07 on Windows XP

I have a SOAP client that works perfectly with HTTP, but gives an UnknownHostException if I try HTTPS. The error is returned in the SOAP body as follows:

<soapenv:Body xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"><soapenv:Fault><faultcode>soapenv:Server.userException</faultcode><faultstring>java.net.UnknownHostException: x</faultstring><detail><ns1:stackTrace xmlns:ns1="http://xml.apache.org/axis/">java.net.UnknownHostException: x

The message itself is encrypted (yes, the customer wants it encrypted twice!), base 64 encoded and then embedded in a wrapper SOAP request:

encoded = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>" +
"<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\">" +
"<soapenv:Body>" +
"<base64binary>" + encoded + "</base64binary>" +
"</soapenv:Body>" + "</soapenv:Envelope>";
SOAPMessage smsg = MessageFactory.newInstance().createMessage(new MimeHeaders(), new byteArrayInputStream(encoded.getBytes()));

The SOAP request is sent using:

SOAPConnectionImpl conn = (SOAPConnectionImpl) SOAPConnectionFactoryImpl.newInstance().createConnection();
conn.setTimeout(new Integer(15000)); //15 seconds
SOAPMessage response = conn.call(smsg, endpoint);
conn.close();


So far, I've tried adding the domain to my hosts file, installing the server'sSSL certificate with keytool, and adding the lines
System.setProperty("javax.net.ssl.trustStore", "C:\\Program Files\\Java\\jre1.6.0_07\\bin\\client.keystore");
System.setProperty("java.protocol.handler.pkgs","com.sun.net.ssl.internal.www.protocol");
Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());

at the start, but it just gives the same error. I tried various port numbers, and changed the URL to https://www.facebook.com/login.php just to see if it was the server, but I still get the same error. No idea what this 'x' in 'UnknownHostException: x' is meant to be either!

Anyone have any ideas on how I can investigate this further?
