Post data to https URL not working!!

Question

I currently have an issue with tunnelling through a 1.1 proxy with JSSE.
I used the SSLTunnelSocketFactory class (as defined in http://www.javaworld.com/javaworld/javatips/jw-javatip111-p2.html) and
tried to use it in my code.
Unfortunately, it doesn't work.
I'm trying to connect to a secure (https) website and post some xml to
it then read the response.
I write the xml to the output stream and then try to open the input
stream for reading back the response.
I get the following error:
Connection aborted by peer: socket write error
Does anyone have an example of code that will do a post of xml (or any
data) to a secure URL and read the results? Whether it's using apache's
httpclient, JSSE or something else?
Thanks for any help you can give.

Here's the code where it tries to connect:
String proxyHost = "212.120.142.235";
String proxyPort = "8088";
String response = "";
Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
System.setProperty("java.protocol.handler.pkgs",
"com.sun.net.ssl.internal.www.protocol");
System.setProperty("https.proxyHost",proxyHost);
System.setProperty("https.proxyPort",proxyPort);
url = "https://website/remote.cgi";
URL remoteURL = new URL(url);
HttpsURLConnection connection = (HttpsURLConnection)remoteURL.openConnection();
if(connection instanceof com.sun.net.ssl.HttpsURLConnection){
((com.sun.net.ssl.HttpsURLConnection)connection).setSSLSocketFactory
(new SSLTunnelSocketFactory(proxyHost,proxyPort));
connection.setRequestProperty("USER_AGENT", "payandshop.com Connect V1.0 [Java 1.3.0]");
File f = new File(sFileName);
FileInputStream fis = new FileInputStream(f);
StringBuffer sb = new StringBuffer();
int i = 0;
while ((i = fis.read()) != -1)
sb.append((char)i);
try {
connection.setDoOutput(true);
PrintWriter printwriter = new PrintWriter(connection.getOutputStream());
printwriter.println(sb.toString());
printwriter.close();
} catch (IOException ioe) {
// can anything here be recoverable? - stop
System.out.println( "Error writing xml"+ioe.getMessage());
return;
String inputLine = null;
try {
InputStream is = connection.getInputStream();
InputStreamReader isr = new InputStreamReader(is);
BufferedReader bufferedreader = new BufferedReader(isr);
while ((inputLine = bufferedreader.readLine()) != null) {
response += inputLine;
bufferedreader.close();

Hi, the problem is to do with the HTTP 1.1 proxy, not SSL itself.
Basically, if you connect through a proxy that is a 1.1 proxy, the
JSSE classes check for HTTP/1.0 in the status of the connection to
the proxy. This will fail due to the fact that HTTP/1.1 is returned
as part of the string (see javaworld url above for description of problem).
Anyway, my problem is trying to implement a workaround. My post
to the SSL site isn't working correctly.
