刚接触jsp，按照书上的程序试验一下，可出现了好多出错信息！

主要功能是实现一个计数器，将访问者数量保存在count.txt中。
我把count.txt和count.jsp建在同一目录中
源代码如下：
count.jsp

<%@ page contentType="text/html；charset=GB2312"%>
<HTML>
<TITLE>计数器</TITLE>
<BODY>
<center>计数器</center>
<hr>
<%
String path =request.getRealPath("./");
FileReader fr=new FileReader(path+"count.txt");
BufferedReader br=new BufferedReader(fr);
String strNum=br.readLine();
br.close();
fr.close();
%>
<center>您是第<% =strNum% >位访问者。</center>
<%
FileWriter fw =new FileWriter(path+"count.txt");
int Num=Integer.parseInt(strNum)+1;
fw.write(String.valueOf(Num));
fw.close();
%>
</BODY>
</HTML>


运行后提示的信息：
