Question

i am using the following code for establishing Https connection

    HttpsConnection httpConnector = null;
    InputStream in = null;
    Document doc ;
    String content = "";

            try 
                {
               httpConnector = (HttpsConnection)Connector.open(url,Connector.READ_WRITE);
                    httpConnector.setRequestMethod(HttpConnection.GET) ;
                    in = httpConnector.openInputStream();
                    byte[] data = new byte[in.available()];
                    int len = 0;
                    int size = 0;
                    StringBuffer raw = new StringBuffer();
                        while ( -1 != (len = in.read(data)) ) {
                            raw.append(new String(data, 0, len));
                            size += len;
                        }
                        content = raw.toString().trim();
                                }
                   catch(Exception ex)
                   {
                       ex.printStackTrace();
                       return false;  
                   }
                   try{
                    in.close();
                    in =null;
                    httpConnector.close();
                    httpConnector =null;

            }catch(Exception ex)
            {
                Dialog.alert("Error:" + ex.getMessage());
                return false;

            } 
            } 

i think i am able to establish the connection but the values are not coming. i am testing it on Simulator, i have not tested on device

Answer 1

I think your mistake is in the following line:

byte[] data = new byte[in.available()];

The available() method only returns how many bytes are immediately available for reading from the inputstream, but you are using it to initialize the size of the temporary byte array. Since it’s possible that available() returns 0, you may be initializing a zero-length array.

It would be better to just initialize “data” with a fixed-length array.
