<head>

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

<title>My JSP 'demo1.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">



</head>

<body>

<%

Date date=new Date();

out.write(date.toLocaleString()+"<br/>");

%>

<%

//域之间的信息获取

request.setAttribute("data", "abc");//request的域

String data=(String)pageContext.getAttribute("data", PageContext.REQUEST_SCOPE);//用pageContext域获取Request域的内容

out.write(data+"<br/>");

String data2=(String)pageContext.findAttribute("data");//直接寻找data

out.write(data2+"<br/>");

%>

${data}



</body>

</html>
