HttpConnection issue on Nokia 6300

[imraniqbal]

Hi,

I am facing a challenge in J2ME code. When I execute following code on Nokia 6300 it produces service not supported.
i have executed same code on Noka 6100, N73 and 6120 Classic.
Can any guide me about the error. Please look in to the code
I receive error on Sage "2" (if(mHttpConnection.getResponseCode() != HttpConnection.HTTP_OK))

//////////////////// Source Code/////////////////
  private void connect() {
    InputStream ins = null;
    
    String s = new String() ;

    try 
    {
      // Query the server and retrieve the response.
      mWaitCanvas.setMessage("Connecting...");
      mHttpConnection = (HttpConnection)Connector.open(mURL, Connector.READ_WRITE,true);
      mStage = "1";
      mHttpConnection.setRequestMethod(HttpConnection.GET);
      mHttpConnection.setRequestProperty("Connection", "close");
      //mHttpConnection.setRequestProperty("User-Agent", "");
      mStage = "2";
      if(mHttpConnection.getResponseCode() != HttpConnection.HTTP_OK)
      {
          throw (new HTTPException(mHttpConnection.getResponseCode(), mHttpConnection.getResponseMessage()));
          
          //throw (new HTTPException(mHttpConnection.getResponseCode(), mHttpConnection.getResponseMessage()));
      }
      
      mStage = "2.5";
      ins = mHttpConnection.openInputStream();
      mStage = "3";
      // Pull back the server's response. If a content length is not
      // specified, we'll just read 255 bytes.

Hi,

Few check points to ensure your midlet will work with GPRS-

1- Do you have GPRS enabled in your MSISDN.
2- Have you configured the proper ASSCESS POINT.
3- Are you able to browse the web using native browser.

Please let us know so that we can help you further.

Hi Iqbal,

On S40 3rd Ed. onwsrds devices MIDlets have issues of connecting to GPRS with WAP APN. In simple words the midlet can not connect using basic GPRS plans provided by the operators.

You can verify this by downloading any third part appliucation such as opera mini or gmail.

If you have the INTERNET APN then the MIDlet will work smoothly.

Hope this will help you.

Hi,

I have tested same application on Sony Ericsson K700i and gives same error. But woking fine on Blackberry.

In addition to what others have answered below, you say that you are able to browse on the phone, but does for example Opera Mini (or any other MIDlet connecting to network) work? As MIDlets are using a predefined access point, browser might work but MIDlets do not.

Issue Resolved

Can I get the list of Acces Points or Can i get the Preffered/ Selected Access Point name in Midlet like Opera Mini shows the preffered Access pont's name before going to connect GPRS.

6300 uses preffered acces point for third party applications.

Thakns for yor guidance. I appreciate.
