j2me

I am developing a little J2ME application that will read our grades from our university's server. With Desktop Applications, It is fine, I can do it but in J2ME, it always gives me this error, even I use well-known services like HTTPS Google, I still get the same error.

        urlConn = (HttpsConnection) Connector.open("https://stars.bilkent.edu.tr/srs/ajax/login.php");
        urlConn.setRequestMethod(HttpsConnection.POST);
        urlConn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");    
        o = urlConn.openOutputStream();
        // Sending my POST requests to server
        input = urlConn.openDataInputStream();

In the last line I always get the error I mentioned above. What should I do about it?
