jsp中框架页面请求中的中文编码问题

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>

String cond ="flowname = '"+ request.getParameter("flowname")+"'";

// out.println(cond);

HttpSession sess = request.getSession();

int allpage = 0;//页数

String pageNo = request.getParameter("pageNo");

//pageNo为null,则赋值为1

if(pageNo==null){

pageNo="1";

sess.setAttribute("flowname",cond);

}

else{

cond = (String)sess.getAttribute("flowname");

// out.println(cond);

}

int p = Integer.parseInt(pageNo);//当前页

ArrayList al = new ArrayList();

int size=0;

try{

DAMInterfaceApp dapp = new DAMInterfaceApp();

Verify ver = new Verify(dapp);

ver.login("admin","admin");

QueryAssetExt quExt = QueryAssetExt.getInstance(dapp);

String strQueryResult = "";

try

{

strQueryResult = quExt.queryAllAssets(150,cond, "", "", 0);

}

catch(Exception qe)

{

System.err.print("错误：调用博思查询接口QueryAssetExt.queryAllAssets出错，错误信息为："+qe.getMessage());

}

//对得到的查询结果进行解析
