<%

Date date=new Date();

%>

<%

//域之間的信息獲取

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

String data=(String)pageContext.getAttribute("data", PageContext.REQUEST_SCOPE);//用pageContext域獲取Request域的內容

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

String data2=(String)pageContext.findAttribute("data");//直接尋找data

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

%>

${data}



</body>
