  1. sorry
    String nameOfTextFile = "count.txt";
    -->
    String nameOfTextFile = "/tomcat/webapps/ROOT/count.txt";
      

  2. or
    String nameOfTextFile = "count.txt";
    file = new BufferedReader(new FileReader(nameOfTextFile));
    -->
    String nameOfTextFile = "count.txt";
    file = new BufferedReader(new FileReader(request.getRealPath(nameOfTextFile)));
      

  3. 这样就正常了!
