想做个类似google日历的东西，不过要比它简单很多
RT，功能不需要google那么强大，只要点击日历上的某个日期，就能显示那天有没有事情提醒，不需要像google那样精确到小时。我的后台是ssh2的，感觉比较难的是如何在jsp页面中嵌入日历框，原来试过在jsp页面顶上直接加JS代码，那么做日历是可以显示的，但点击的功能就让我犯难了啊。还是帖一些页面的代码吧，反正也是网上down的：
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<%@ taglib uri="/struts-tags" prefix="s"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

    <base href="<%=basePath%>">
