   response.setContentType("text/html;charset=gb2312");


You set the charset to gb2312...


   response.setHeader("Cache-Control", "no-cache");
   response.setHeader("Pargma","no-cache");


(Note: that should read "Pragma", not "Pargma".)


   StringBuffer sb=new StringBuffer("");
   sb.append
("北京yangzhousuzhou");
   sb.append("");
   PrintWriter out=response.getWriter();
   out.write(sb.toString());


But you don't send gb2312 bytes back to the client. Java strings are
Unicode (internally, UTF-16be), and when you convert them to bytes
without specifying what encoding to use, you get the "default platform
encoding", which could be just about anything, depending on what
platform you are on, the JVM and appserver you are using, the version,
the phase of the moon, etc.

If you want to convert the string to gb2312 bytes, you need to convert
the string to gb2312 bytes.

out.write(sb.toString().getBytes("gb2312"));

N.B. this can throw an UnsupportedEncodingException, in theory,
although it shouldn't for well-known encodings, in practice.

Maybe you should url-encode them first before sending them to client through
ajax response.

I believe that in order to compile I18N code you must
do two things: make sure your source is in an I18N
format and tell the compiler to use that encoding.

I think with Sun's compiler you can use the -encoding
option.

Ajax can't receive Chinese code from action of struts2

[red phoenix]

when ajax receive information which include Chinese code from action of
Struts2,ajax will show chinese code into confusion code,but if ajax receive
information which include Chinese code from jsp, ajax will show correct
Chinese code.I don't know why raise this error!  How to correct it?

My code is follows:
/*a.html  saved as UTF-8 code*/


var xmlhttp;
function CreateXmlRequest(){
   try {
   xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");
   }
   catch(e){
   try{
   xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
   }
   catch (e){
   try{
   xmlhttp = new XMLHttpRequest();
   }
   catch (e){
   xmlhttp = false;
   }
}
   }
}

function checkUserName(){
   xmlhttp.open("get", "example/test.action", true);
   xmlhttp.onreadystatechange = updatePage;
xmlhttp.send(null);
}

function updatePage(){
   try{
   if(xmlhttp.readyState == 4){
alert(xmlhttp.responseText);
   }
   }
   catch (e){}
}
CreateXmlRequest();






/*HelloWorld.java  saved as UTF-8 no BOM code,I compile as C:>javac -d .
HelloWorld.java  */
package example;
import org.apache.struts2.ServletActionContext;
import java.io.*;
import javax.servlet.http.HttpServletResponse;
public class HelloWorld extends ExampleSupport {
   public String test() throws Exception {
   HttpServletResponse response;
   response=ServletActionContext.getResponse();
   response.setContentType("text/html;charset=gb2312");
   response.setHeader("Cache-Control", "no-cache");
   response.setHeader("Pargma","no-cache");
   response.setDateHeader("Expires",0);
   StringBuffer sb=new StringBuffer("");
   sb.append
("北京yangzhousuzhou");
   sb.append("");
   PrintWriter out=response.getWriter();
   out.write(sb.toString());
   out.close();
   return null;
   }
}

/*struts.xml*/

http://struts.apache.org/dtds/struts-2.0.dtd";>

   
   
   

/*example.xml*/

http://struts.apache.org/dtds/struts-2.0.dtd";>

   
   
   /example/a.jsp
   
   


When I run a.html,ajax should alert information
"北京yangzhousuzhou",but
it shows "?confusion
characters?yangzhousuzhou"

Anybody know how to do it?
Thanks!
