Assume data comes in a java.util.Map as key/value pairs.

Map data = getParametersFromSomewhere();

StringBuffer buffer = new StringBuffer(100);
for (Iterator i = data.keySet().iterator(); i.hasNext();) {
    Object key = i.next();
    buffer.append(key.toString() + "=" +
URLEncoder.encode((data.get(key)).toString()) + "&");
}
String postString = buffer.toString();
URL url = new URL( "..." );
HttpURLConnection connection= (HttpURLConnection) url.openConnection();
connection.setRequestMethod("POST");
connection.setRequestProperty("Content-type",
"application/x-www-form-urlencoded");
// A content-length header must be contained in a POST request
connection.setRequestProperty("Content-length", postString .length());
OutputStream out = new BufferedOutputStream(connection.getOutputStream());
out.write(postString.getBytes());
out.close();
InputStream in = new BufferedInputStream(connection.getInputStream());
int statusCode = connection.getResponseCode();
processInput(in);
in.close();
