Send image multipart (Thread)

Question

I send image divided into some parts (about 500 bytes per part) from my device through http connection. after i send image part,MIDlet listen for the response from server. If the response received then i send the next part....
The problem is: in emulator it works fine but in real device it often doesn't received the response (probably because of the poor quality of gprs in my country) so it looks hang up.. i'm trying to solve this by adding Command to continue (it will send the last part again) but it catch IlegalStateThreadException
how can i stop myThread that is currently running and waiting for response that will never come... and start the thread for re-send the part again?????

Friends
I am writting a application to send Image object from midlet to a servlet and save that as a file on server. I am converting Image to byte[] and at the server end reading the data from stream and save it.
I am converting Image to byte array line by line and writting it over http connection line by line.
the problem is I am not able to save the real image at server.
The file gets created of the size of the data sent but not able to open the image.
the code for image to array [] is
if (initialized) {
if (hasNextLine()) {
// Get one line of pixels out of the image, each integer value
// represents a pixel (0xAARRGGBB)
int[] temp = new int[width];
raster.getRGB(temp, 0, width, 0, y, width, 1);
// Convert pixels to gray scale, byte is sufficient
byte[] pixels = new byte[width];
for (int x = 0; x < temp.length; x++) {
// Get brightness of pixel (R + G + B) / 3; ignore alpha
pixels[x] = (byte) ((((temp[x] & 0x00FF0000) >> 16)
+ ((temp[x] & 0x0000FF00) >> 8) + (temp[x] & 0x000000FF)) / 3);
// Process and compress the image line
byte[] processedImgLine = processImageLine(pixels);
byte[] compressedImgLine = compressImageLine(processedImgLine);
// Update position in image
y++;
return compressedImgLine;
// No more lines
else {
throw new NoSuchElementException("No more lines in image");
and writing it in while loop line by line
and at the server side
InputStream in = request.getInputStream();
BufferedReader r = new BufferedReader(new InputStreamReader(in));
StringBuffer buf = new StringBuffer();
String line;
while ((line = r.readLine()) != null) {
buf.append(line);
String s = buf.toString();
// write a file
FileOutputStream f1;
File directory = new File("C:/Image/");
directory.mkdirs();
String path = "C:/Image/image.jpeg";
//byte[] data = Base64.decode(s);
ImageIcon imageIcon = new ImageIcon(s.getBytes());
Image image = imageIcon.getImage();
System.out.println(" Image "+image);
ImageIO.write(toBufferedImage(image), "jpeg",
new File("C:/Image/jpeg.jpeg")) ;Can anyone tell me the solution
