http connection not working on phone
Hi i am trying to connect to a http server using the new nokia n95 phone with T-mobile web and walk(Unlimited 3g internet access)
on the emulaor and on the phones wifi connection, it works. But when i try connecting to the server using gprs/3g it doesnt. The response code never equals to OK . here is my code below:
I know it is not working because has soon as the program makes an attempted to connect, the root.notifyDestroy() closes the application as i expect it too
server = (HttpConnection) Connector.open(url);
server.setRequestMethod(HttpConnection.POST);
int rc = server.getResponseCode();
if (rc == HttpConnection.HTTP_OK)
{
is = server.openInputStream();
}
else
{
root.notifyDestroyed();
Alert alert =new Alert ("Error");
alert.setString("Error, server is down");
alert.setTimeout (5000);
Display.getDisplay(root).setCurrent(alert);
thrownew IOException("HTTP response code: " + rc);
}

its hard to tell has i cant debug from the phone device. Al i can say is that the response code is not equal to OK.
I have checked my gprs settings and there is nothingw rong on it as far as ic an see because i can browse the web and use other programs like FRING to access the web
Its strange because on the emulator and on a wifi connection from the phone it works! Can anybody give me some ideas on why it is not working?

I had all sorts of strange problems getting http connect to work from phones. Most of my problems were resolved by adding every single header I could find that tells the carrier's gateway to leave it alone. Try adding these headers to the connection from the phone, and the response from the server:
connection.setRequestProperty( "User-Agent","Profile/MIDP-1.0 Configuration/CLDC-1.0");
connection.setRequestProperty( "Content-Type", "application/octet-stream");
connection.setRequestProperty( "Content-Length", ""+(allContentToSend.length));
connection.setRequestProperty( "Cache-Control","no-store");
connection.setRequestProperty( "Cache-Control", "no-cache");
connection.setRequestProperty( "Pragma","no-cache");
connection.setRequestProperty( "Cache-Control", "no-transform");
connection.setRequestProperty( "Connection", "Keep-Alive");
connection.setRequestProperty( "Proxy-Connection", "Keep-Alive");
The content-type will depend on what you are sending. octet-stream is for binary data. If you are just encoding parameters in your POST you may need something else like "application/x-www-form-urlencoded".
The content-length is obviously dependant on what you are sending. The rest of the properties simply tell whoever is transporting the request to leave it alone.
TEMP_MOVED sounds like a redirect or some odd thing. Maybe the carrier is caching the response, and you are actually getting something unnexpected.
Hope this helps.
