最近有这么一个需求，一个主页面从request中拿到请求的参数（中文）,主页面里有两个Frame,
每个Frame嵌着一个jsp,如何把主页面中得到的中文参数值传入Frame里去呢，后来发现应该先把
中文编码成unicode,然后传给frame中的jsp，frame中的jsp再解码，程序清单如下:
index.jsp
====================================================================
<%@ page contentType="text/html; charset=UTF-8" %>
<%@ page import="java.net.URLEncoder" %>
<%
String flowname = request.getParameter("flowname");
%>
<html>
<head>
<title>

</head>
<frameset rows="70%,*" cols="*" framespacing="1" frameborder="yes" border="0">
<frame src="assetlist.jsp?flowname=<%=flowname%>" name="topFrame" frameborder="1" scrolling="auto" noresize>
<frame src="#" name="acceFrame" scrolling="auto">

</html>
