Like this:
        //upload
        String fileName = formFile.getFileName();
     Sting  destFile = "c:/upload/" + fileName;//path to save the upload file on server
     try {
             InputStream     in = formFile.getInputStream();
          OutputStream     out = new FileOutputStream( new File(destFile) );
          int n = 0;
          byte[] buff = new byte[8192];
          while( (n = in.read( buff, 0, 8192 )) != -1 ) {
               out.write( buff, 0, n );
          out.close();
          in.close();     
        }catch(Exception e){
        //download
        String serverFile = "c:/upload/a.txt";//file path on server to be downloaded
        File serverF = new File(serverFile);
        response.setContentType("text/html");
     response.setHeader("Content-Disposition","attachment;filename="+serverF.getFileName()+";");
     try {
         ServletOutputStream outStream = response.getOutputStream();
         FileInputStream stream = new FileInputStream(serverF);
         BufferedInputStream  bis = new BufferedInputStream(stream);
         BufferedOutputStream bos = new BufferedOutputStream(outStream);
         byte[] buff = new byte[2048];
         int bytesRead;
            try{
             while(-1 != (bytesRead = bis.read(buff, 0, buff.length))) {
                  bos.write(buff, 0, bytesRead);
         } catch (Exception e) {
            } finally {
        if (bis != null) bis.close();
        if (bos != null) bos.close();
        if (stream != null) stream.close();
     }catch (IOException e){
     }
