How do I login and download a file from a https web page from Java?

I have to login into a https web page and download a file using Java. I know all the URLs beforehand: baseURL = // a https URL; urlMap = new HashMap(); urlMap.put("login", new URL(baseURL, "exec.asp?login=username&pass=XPTO")); urlMap.put("logout", new URL(baseURL, "exec.asp?exec.asp?page=999")); urlMap.put("file", new URL(baseURL, "exec.asp?file=111")); If I try all these links in a web browser like firefox, they work. Now when I do: urlConnection = urlMap.get("login").openConnection(); urlConnection.connect(); BufferedReader in = new BufferedReader( new InputStreamReader(urlConnection.getInputStream())); String inputLine; while ((inputLine = in.readLine()) != null) System.out.println(inputLine); in.close(); I just get back the login page HTML again, and I cannot proceed to file download. Thanks!
