计数器

　　计数器是一般网站必备的东东，别小看它了，每当站长看着小小计数器上的数字飞速增长的时候，感觉实在是好极了。以前我们用cgi、asp来写计数器，这方面的文章很多了，在这里，我们将会采用目前比较流行的jsp技术演示如何做一个计数器。
其中我们用到了两个文件，test.jsp文件用于在浏览器中运行，counter.java是后台的一个小java bean程序，用来读计数器的值和写入计数器的值。而对于计数器的保存，我们采用了一个文本文件lyfcount.txt。

下面是详细的程序代码(test.jsp放到web目录下，counter.java放到class目录)：

//test.jsp文件
