POST from HttpsURLConnection

I am trying to create web client for  form-based logging  .
here is the piece of code I am using.
All values I am getting by parsing start up form.
When looking at Post request in IEWatch one line is different:
(Method-Line)      POST /c/a/WirelessLogIn HTTP/1.1
I am using just       connection.setRequestMethod("POST");   without any parameters
I am not sure  if this makes any difference.

Here is what  I am posting:
      String body    ="USERID="+v_account+"&PASSWORD="+v_pin
      url = new URL(t_url+body);
      connection = (HttpsURLConnection)url.openConnection();
      //connection.setRequestProperty("Accept", "image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/x-shockwave-flash, application/, application/msword, */*");
      connection.setRequestProperty("Accept", "*/*");
      connection.setRequestProperty("Referer", "");
      connection.setRequestProperty("Accept-Language" , "en-us");
      connection.setRequestProperty("Accept-Encoding", "gzip, deflate");
      connection.setRequestProperty("Content-Type" , "application/x-www-form-urlencoded") ;
      connection.setRequestProperty("User-Agent",  "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.0.3705; .NET CLR 1.1.4322; Media Center PC 4.0)");
      connection.setRequestProperty("Host", "");
     // connection.setRequestProperty("Content-Length","120");    
      connection.setRequestProperty("Connection", "Keep-Alive");
      connection.setRequestProperty("Cache-Control", "no-cache");
      connection.setRequestProperty("Cookie", cookie);

 The response is :

<TITLE>Page Unavailable</TITLE><BODY>
/html/errors/404.html is unavailable, please contact system administractor.

As you can see I've commented out one line       // connection.setRequestProperty("Content-Length","120");  
because with this line the sessin hangs and I am getting no response at all .
How to solve this issue ???

your passing the parameters as a GET.
For a post you need to instead write them to the connections output sytream

Yes !!!  It works , Thanks !!. I've seen this example before but it looks like not quite got it before. POST and GET is a little bit confusing,
somtimes I was using GET method to login, and it worked, but in this situation it had to bePOST .

Great, I am really approciated
