Java Programming

This code generates a 0 byte *.zip file and doesn't throw any errors. BUFFER is set at 20480. What am I doing wrong?

    private void zipEm()
  {
    File directory = new File(_imageFolderPath);
    String files[] = directory.list();

    try {
      BufferedInputStream origin = null;
      FileOutputStream dest = new FileOutputStream(_zipFilePath);
      ZipOutputStream zip = new ZipOutputStream(new BufferedOutputStream(dest));
      
      byte data[] = new byte[BUFFER];
      
      File f = null;
      ZipEntry entry = null;
      FileInputStream fi = null;
      int count;
      
      for (int i=0; i <files.length; i++)
      {
        fi = new FileInputStream(files);

origin = new BufferedInputStream(fi, BUFFER);

entry = new ZipEntry(files[i]);

zip.putNextEntry(entry);



while((count = origin.read(data,0,BUFFER)) != -1)

{

zip.write(data,0,count);

}

count = 0;

origin.close();

}

zip.close();

}

catch (Exception e)

{

// handle exception

e.printStackTrace();

}

}
