Ajax中文问题

[进一步-海阔天空]

我通过这样的代码向客户端返回XML。
response.setContentType("text/xml");
PrintWriter out = new PrintWriter(response.getOutputStream());
System.out.println(xmlutil.transformDOM(doc));
out.println(xmlutil.transformDOM(doc));
out.close();
在控制台打出中文是对的。
<?xml version="1.0" encoding="UTF-8"?>
<ARCXML version="1.1">

</ARCXML>

但在客户端用
alert(xmlHttp.responseText);
弹出了这样的结果，跟服务器端明显不一致，是什么原因呢？如何解决？

关键是你服务器端的编码 是否和 客户端一致

改了一下编码alert(xmlHttp.responseText)显示是对的，但xmlHttp.responseXML还是不对，为什么？

prototype.js

[o光o]

private void setHead(HttpServletRequest request,HttpServletResponse response) throws Exception{
response.setHeader("Pragma","no-cache");
response.setHeader("Cache-Control","no-cache");
response.setDateHeader("Expires", 0);
request.setCharacterEncoding("GBK");
response.setContentType("text/xml;charset=GBK");
response.getWriter().println("<?xml version='1.0' encoding='GBK'?>");
}

private void setHead(HttpServletRequest request,HttpServletResponse response) throws Exception{
response.setHeader("Pragma","no-cache");
response.setHeader("Cache-Control","no-cache");
response.setDateHeader("Expires", 0);
request.setCharacterEncoding("UTF-8");
response.setContentType("text/xml;charset=UTF-8");
response.getWriter().println("<?xml version='1.0' encoding='UTF-8'?>");
}

统一编码...

是XML文件的用xmlHttp.responseXML.xml

[huaguol]

在java类里加：
response.setContentType("text/xml;charset=UTF-8");
response.setHeader("Cache-Control", "no-cache");
