Extract tar.gz file

Question

Hi,
I have a file with extension tar.gz and i need to extract it. I tried with GZIPInputStream class of java.util.zip package but could not do it. Below is the code snippet for the same. Please suggest the way we can handle this problem in Java.
String filename = "C:\\TarFile\\Test.20110519_123033_00001.tar.gz";
               final int BUFFER_SIZE = 2048;
               try {
                    BufferedOutputStream dest = null;
                    FileInputStream fis = new FileInputStream(filename);
                    GZIPInputStream zis = new GZIPInputStream(new BufferedInputStream(fis));
                    int len;
                    FileOutputStream fos = new FileOutputStream("C:\\TarFile\\Test.20110519_123033_00001.tar");
                    dest = new BufferedOutputStream(fos, BUFFER_SIZE);
                    byte data[] = new byte[BUFFER_SIZE];
                    while ((len = zis.read()) != -1) {
                         //int count;
          // write the files to the disk
          dest.write(data, 0, len );
     //dest.flush();
     dest.close();
          zis.close();
}catch(Exception e) {
Thanks.

By words "could not do it" , it should be very much clear that - i could not extract the file tar.gz completely. That is what the actual problem is. I understand people should have commonsense to understand it.
Of course we understand it. What we don't understand is what happened instead. Exception? Data corruption? Nothing? Computer exploded?
You aren't going to get anywhere here or indeed in life by making rude remarks about common sense to people who are trying to help you. You provided one binary digit of information. You needed to provide more. Would you accept that as a bug report from a user? or would you ask for some details?
