HttpConnection.getResponseCode() return -1

Question

Hi guy's
I am developing a midp application which is communicate with server and display the result on the client using HttpConnection.Basically i am from bangalore,India and using Airtel,Vodafone connections for GPRS. My jar file is properly working in the Sony Ericsson models(k800i,k310i) with airtel and vodafone connections. But the same jar file is failed to communicate with server in Nokia models. HttpConnection.getResponseCode() return -1 in Nokia 6020,6070,6300 devices. Even N6030 is also return same value with vodafone. But same time application working fine in another 6030 model with airtel. Please look at my source code below.
private static String requestToServer(final String url, final String data)throws IOException {
HttpConnection httpCon = null;
InputStream inputStream = null;
String result = null;
try {
while (true) {
httpCon = (HttpConnection) Connector.open(connectionUrl,Connector.READ_WRITE);
httpCon.setRequestMethod(HttpConnection.POST);
final String conf = System.getProperty("microedition.configuration");
final String prof = System.getProperty("microedition.profiles");
httpCon.setRequestProperty("User-Agent","Profile/" + prof + " Configuration/" + conf);
writeDataToConnection(httpCon, data);
if (!isRedirectResponse(httpCon)) {
break;
connectionUrl = httpCon.getHeaderField("Location");
httpCon.close();
inputStream = httpCon.openInputStream();
result = readStreamData(inputStream);
} catch (final ClassCastException e) {
throw new IllegalArgumentException("Not an HTTP URL"); }
catch (final IOException e) { throw e; }
catch (final Exception e) { throw e; }
finally {
if (inputStream != null) { inputStream.close(); }
if (httpCon != null) { httpCon.close(); }
return result;
private static void writeDataToConnection(final HttpConnection c, final String data) throws IOException {
final OutputStream os = c.openOutputStream();
try {
final DataOutputStream dos = new DataOutputStream(os);
dos.writeUTF(data);
dos.flush();
catch(IOException e) { throw e; }
finally { os.close(); }
private static boolean requestToServer(final HttpConnection httpCon)throws IOException {
boolean result = false;
final int conResponseCode = httpCon.getResponseCode();
switch (conResponseCode) {
case HttpConnection.HTTP_OK:
result = false;
break;
case HttpConnection.HTTP_MOVED_TEMP:
if (DEBUG_REDIRECT) {
System.out.println("Request is redirected"); }
result = true;
break;
default:
throw new IOException("HTTP response code: " + conResponseCode);
return result;
In the Nokia models, the httpCon.getResponseCode() return -1. Can anybody tell me, whats the problem and what the solution for this please.

use this ---> return new int[]{1,3};
