Has anyone got a sample code or utility that will allow a POST request
to be created to a SSL/HTTPS url?

I've spent a few hours googling and got solutions for HTTP and those
that I have found for HTTPs haven't worked.

Here are a small working example:

package october;

import java.io.*;
import java.net.*;
import java.security.cert.*;

import javax.net.ssl.*;

public class HttpsPost {
     public static void main(String[] args) throws Exception {
         SSLContext sslctx = SSLContext.getInstance("SSL");
         sslctx.init(null, new X509TrustManager[] { new MyTrustManager()
}, null);

HttpsURLConnection.setDefaultSSLSocketFactory(sslctx.getSocketFactory());
         URL url = new URL("https://www.xxxx.dk/htbin/tell2");
         HttpsURLConnection con = (HttpsURLConnection) url.openConnection();
         con.setRequestMethod("POST");
         con.setDoOutput(true);
         PrintStream ps = new PrintStream(con.getOutputStream());
         ps.println("f1=abc&f2=xyz");
         ps.close();
         con.connect();
         if (con.getResponseCode() == HttpsURLConnection.HTTP_OK) {
             BufferedReader br = new BufferedReader(new
InputStreamReader(con.getInputStream()));
             String line;
             while((line = br.readLine()) != null) {
                 System.out.println(line);
             }
             br.close();
         }
         con.disconnect();
     }
}

class MyTrustManager implements X509TrustManager {
     public void checkClientTrusted(X509Certificate[] chain, String
authType) {
     }

     public void checkServerTrusted(X509Certificate[] chain, String
authType) {
     }

     public X509Certificate[] getAcceptedIssuers() {
         return new X509Certificate[0];
     }
}
