        byte[] buf = new byte[1024];
        int len=0;
        /*len = fis.read(buf);
        System.out.println(new String(buf,0,len));
        len = fis.read(buf);
        System.out.println(new String(buf,0,len));*/
        while((len = fis.read(buf))!=-1){
            System.out.println(new String(buf,0,len));
