jsp中java代码显示问题
在MyEclipse中新建一个jsp页面,然后在里面定义java变量方法,以及java代码后(<%! %><% %>),浏览器中直接把<%! %>
<% %>这些当做普通字符串给输出了,这是咋回事呢?

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
  <base href="<%=basePath%>">
   
  <title>My JSP 'index.jsp' starting page</title>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">  
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">
<!--
<link rel="stylesheet" type="text/css" href="styles.css">
-->
  </head>
  <body>
  <%=new Date() %>
  This is my JSP page. <br>
  </body>
</html>



------解决方案--------------------
我测试能显示下面:

Wed May 23 06:41:37 CST 2012 This is my JSP page. 

<% %>没有显示啊!
------解决方案--------------------
只会输出
<%=new Date() %>

浏览器输出要用out.print()
------解决方案--------------------
应该没问题啊,我的跟你一样写的啊

------解决方案--------------------
<%! %>是声明
