Help with HTTPS

Question

I have a vendor with an HTTPS server application. I connect to the server, and send data via Posts, and they reply.
Here is an example of the code:
try{
System.setProperty("java.protocol.handler.pkgs","com.sun.net.ssl.internal.www.protocol");
     Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
     URL u = new URL(url);
     HttpsURLConnection huc = (HttpsURLConnection) u.openConnection();
     huc.setDoOutput(true);
     huc.setDoInput(true);
     huc.setRequestMethod("POST");
     huc.connect();
     String sndData = URLEncoder.encode("Data sent to remote application);               
     OutputStreamWriter osr = new OutputStreamWriter(huc.getOutputStream(),"UTF-8");
     BufferedWriter bw = new BufferedWriter(osr);
     bw.write(sndData, 0, sndData.length());
     bw.flush();               
     bw.close();
     InputStreamReader isr = new InputStreamReader(huc.getInputStream());
     BufferedReader br = new BufferedReader(isr);
     String response = br.readLine();
     processResponse(response);
     huc.disconnect();
This code works fine. However, I need to build on this. I would like to keep the HTTPS connection, and send/receive multiple times. Any suggestions?
Thanks.

Hi,
I have exactly the same code, but have on:
avax.net.ssl.HttpsURLConnection con = (javax.net.ssl.HttpsURLConnection)url.openConnection();
following exception:
Exception in thread "main" java.lang.ClassCastException: com.sun.net.ssl.internal.www.protocol.https.HttpsURLConnectionOldImpl
     at SimpleClient.madeObjectCall(SimpleClient.java:67)
     at SimpleClient.<init>(SimpleClient.java:26)

What do you do different?
Thx a lot.
