Struts Encode question

[red phoenix <ro...@gmail.com>]

I want to get a value from a JSP in Action,like follows:
/*jsp*/
<%@ page contentType="text/html;charset=gb2312" %>
<html:text property="ex"/>
....

And I input a Chinese Word in ex area,then I get the ex value from a
Action,like follows:
/*Action*/
public ActionForward execute(ActionMapping mapping,ActionForm
form,HttpServletRequest request,HttpServletResponse response) throws
Exception {
   request.setCharacterEncoding("gb2312");
   String ex=request.getParameter("ex");
 ....

But I find ex don't show propertly,it should show right Chinese word,but it
shows ???????í?±,I use DynaActionForm,like follows:
<form-bean
   name="tt"
  type="org.apache.struts.action.DynaActionForm">
   form-property
   name="ex"
   type="java.lang.String"/>
 ...

Why struts don't show propertly? How to show Chinese Word in Struts Action?

Thanks.

The call to setCharacterEncoding() looks suspicious to me; I don't think 
that should be necessary. You have the character encoding declared in 
the JSP page directive, which is good; you may also need to add a 
meta-equiv content type tag to your page (in the HTML HEAD section) to 
help the browser determine the character encoding to use.

Also be wary of displaying non-ASCII string values with e.g. 
System.out.println(); the console output may be misleading if it's using 
the wrong character encoding. Test your 'ex' variable's value against a 
known-good string constant to verify it rather than relying on printing it.

HTH,
