浙江大学宁波明州医院:求个JSP小程序，满意的多加100分，在线等

JSP，如果是课件，最好做个《用户登陆》或者《留言本》。
网上也有很多免费下载源代码的网站：

http://www.csdn.net 网络开发者
http://www.onjava.com 教程不多
http://www.javaworld.com
http://www.javaworld.com.tw 台湾的网站哦,10万帖
http://forum.javaeye.com

实在找不到,可以到Google搜一下!
如果还是没有，那，我给你：w_binglong@yahoo.com.cn

楼主注意：

楼上那个可能对你来说不真是，用这个吧

jsp 计数程序 我自己写的

<%

BufferedReader inf = new BufferedReader(new FileReader("/path/to/counter.txt"));
int tmp = Integer.parseInt(inf.readLine());
int i=0;

try {

i = Integer.parseInt(request.getSession().getValue("tal").toString());
} catch (NullPointerException t) {i=0; }

if (i==0) {
tmp++;

PrintWriter outf = new PrintWriter(new BufferedWriter(new FileWriter("/path/to/counter.txt")));
outf.println(tmp);
outf.close();
inf.close();
request.getSession().putValue("tal", "1");
}

BufferedReader inf2 = new BufferedReader(new FileReader("/path/to/counter.txt"));
%>
<%
String zeroes="";
String hits = inf2.readLine();
inf2.close();
for (int t=0; t < 8-hits.length(); t++) {
zeroes=zeroes+"0"; }
out.println(zeroes + hits);
%>

给你一个简单清晰而且有趣的例子给你呵呵,能反映出基本JSP的原理了~:
<%! static int a = 0;%>
<% static int b = 0;%>
<%=a++%> <%=b++%>

JSP中捕获 OUT 输出的例子

在CSDN里面看了一篇关于将动态JSP内容保存为静态页面的文章,忘记网址了,大家可以搜索一下 :)
他没有提供源代码,然后自己测试着写了一个.
主要想法是捕获 out 的输出后,可以保存到一些静态文件中,可以写一个 JSP的缓冲程序.
代码有待完善, 希望有这方面经验的朋友来共同完善.

在RESIN环境中测试成功,没有在tomcat其他服务器下测试,还存在一个问题,就是不能够同时输出到IE浏览器中.

?

以下为程序代码, 例如保存到 test.jsp 文件中,然后在IE中执行

http://....../test.jsp

将看不到任何输出,但是可以在后台resin的DOS窗口中看到输出的内容

<%@ page language="java" contentType="text/html;charset=gb2312"%>
<%@ page import="java.io.*"%>
<%@ page import="java.util.*"%>
