ajax 利用Servlet向html传值中文问题

用servlet PrintWriter 一个xml 里面有中文 ajax 的xmlhttprequest.responseXML 读取xml文件信息是js显示的中文为乱码，请问有没有什么办法可以解决。直接点就是java类给js传值，中文乱码问题。多谢各位。虽然可以把它们都转成%12%AB可以解决，但是有些麻烦，衷心求教，多谢……

ps: 您的js是二进制文件么？？
    我碰到过用eclipse编辑中文，页面上显示的是乱码，用ultraEdit编辑 js 就不会有这个问题。
response.setContentType("text/xml;charset=gb2312");
response.setContentType("text/html;charset=gb2312");
你的xml文件编码方式，文件保存的时候选择编码方式和输出编码方式三者要统一。有3种编码方式可参考：UTF-8、gb2312和gbk。
response.setContentType("text/xml;charset=gb2312");
response.setContentType("text/xml;charset=UTF-8");
在页面上增加那个头部文件了么？声明字体的那部分（jsp中是<%@ page contentType="text/html, charset=gb2312"%>）;
html中也有类似的声明，找一下，加上后，看能否解决
xmlhttprequest.responseXML接受到的xml都是utf-8格式的你需要转码

在js中应该怎么转码呢？求教，在baidu上没找到，多谢
建议全部utf-8
包括数据库.jsp,htm,js,Servlet,javaBeen就不存在什么转码不转码的问题了。
怎么会不行呢？下面是在FireFox中刚刚通过的<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

var xmlDoc;
var http_request=false;

function initXMLHttp() {
if (window.XMLHttpRequest) { // Mozilla, Safari,...
http_request = new XMLHttpRequest();
if (http_request.overrideMimeType) {
http_request.overrideMimeType('text/xml');
}
} else if (window.ActiveXObject) { // IE
try {
http_request = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
try {
http_request = new ActiveXObject("Microsoft.XMLHTTP");
} catch (e) {}
}
}
if (!http_request) {
alert("您需要升级您的浏览器！");
return false;
}
}

function yourfunction(){
initXMLHttp();
http_request.open("get", "rs2.jsp", false);
http_request.setRequestHeader("Content-Type","application/x-www-form-urlencoded");
http_request.send(null);
xmlDoc=http_request.responseXML;
var data=xmlDoc.getElementsByTagName("node1");
document.getElementById("div1").innerHTML=data[0].firstChild.nodeValue;
}
</script>
</head> <body>
<input type="button" onclick="yourfunction()" name="button" value="Click me">
<div id="div1"></div>
</body>
</html>
----------------------------------<%@ page language="java" pageEncoding="gb2312"%>
<%
response.setHeader("pragma","no-cache");
response.setHeader("cache-control","no-cache");
response.setHeader("expires","0");
response.setHeader("content-type","text/xml;charset=gb2312");
        out.println("<docroot><node1>中国</node1></docroot>");
%>
第二个文件改一下，IE和FF都可以了<%@ page language="java" pageEncoding="gb2312"%><%
response.setHeader("pragma","no-cache");
response.setHeader("cache-control","no-cache");
response.setHeader("expires","0");
response.setHeader("content-type","text/xml;charset=gb2312");
out.println("<?xml version=\"1.0\" encoding=\"GB2312\"?>");
out.println("<docroot><node1>中国</node1></docroot>");
%>
我用servlet写的 response xml就是乱码嗷嗷郁闷，结贴，继续研究中……

</html>我把rs2.jsp换成servlet为什么取不到返回值哦。。
大家帮忙public class jugpersonSelectedAction extends Action
{
    public ActionForward execute(ActionMapping actionMapping,
            ActionForm actionForm, HttpServletRequest request,
            HttpServletResponse response) throws Exception
    {
     String forward = "success";
        response.setHeader("pragma","no-cache");
        response.setHeader("cache-control","no-cache");
        response.setHeader("expires","0");
        response.setHeader("content-type","text/xml;charset=gb2312");
        System.out.println("<?xml version=\"1.0\" encoding=\"GB2312\"?>");
        System.out.println("<docroot><node1>中国</node1></docroot>");       return actionMapping.findForward(forward); }
