@RequestMapping(value="/addfile")

public String addfile(ModelMap model, HttpServletRequest req) throws FileUploadException, IOException {

System.out.println("/addfile called");

// Get the image representation

   ServletFileUpload upload = new ServletFileUpload();

   FileItemIterator iter = upload.getItemIterator(req);

   FileItemStream item = iter.next();

   InputStream stream = item.openStream();

   

   // construct our entity objects

   byte[] bytes = IOUtils.toByteArray(stream);

   Blob imageBlob = new Blob(bytes);

   System.out.println("BLOB: " + imageBlob.toString());

   

   String str = new String(bytes,0,bytes.length);

   String[] lines = str.split("\n");

   int i = 1;

   

   SyncInfo syncInfo = new SyncInfo();

   for (String line : lines) {

//System.out.println(i++ + " : " + line);

syncInfo = getSyncInfo(line);

}

       

return prefix + "list";
