I upload a file from a Nokia N97 phone to server, everything works fine but after file is uploaded I want to get response from server. The problem is that I get response only after half a minute or more. From what I see the code blocks in httpConnection.getResponseCode() waiting for response. I tested it on a Sony Ericsson and I get response very fast so I assume is a Nokia N97 problem. (is not a server problem because it works fine on other phones)

Does anyone knows why this thing happens only on Nokia?

Here is a code snippet:

public uploadFile() {

       httpConn = (HttpsConnection) Connector.open(url, Connector.READ_WRITE);
        ...
       //set httpConn parameters and request method 
       ...

       writeParametersAndFileName(os, "text/plain");


       **writeFileToStream(os);** 

       os.write("
".getBytes());
       os.write("--".getBytes());

       os.write(boundary.getBytes());

       os.write("--".getBytes());
       os.write("
".getBytes());

        *//here code blocks on Nokia N97. Same thing happens if I use os.flush() after
        // I send chunks of the file*
         .....
        codeResp = httpConn.getResponseCode();
        // check condition
        checkResponseHeader();

}

public writeFileToStream() {

        InputStream is = null;
        FileConnection c = null;
        try
        {
           c = (FileConnection) Connector.open("file:///"+ sourcePath, Connector.READ);

           if(c.exists()) {
               is = c.openInputStream();

               long fs = c.fileSize();
               while (total < fs) {
                    byte[] data = new byte[512];
                    int readAmount = is.read(data,0,512);                       
                    total += readAmount;
                    os.write(data, 0, readAmount);


            }

            //os.flush();
        }
        catch (IOException ex) {
           //               
        }
        finally
        {
           //close connection

        }

}
