struts2中add cookie 不能再客户端生成cookie文件，为什么？

Question

我做自动登录的功能，是这样操作的：
[code="java"]
package com.zuwoba.presentation.action.account;

import java.util.Map;

import javax.servlet.http.Cookie;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;

import org.apache.struts2.ServletActionContext;
import org.apache.struts2.StrutsStatics;
import org.apache.struts2.interceptor.ServletRequestAware;
import org.apache.struts2.interceptor.ServletResponseAware;

import com.opensymphony.xwork2.ActionContext;
import com.zuwoba.model.User;
import com.zuwoba.model.UserSession;
import com.zuwoba.presentation.action.base.BaseAction;
import com.zuwoba.util.EmailLoginAddress;
import com.zuwoba.util.MD5_Encoding;

  }

奇怪的是，客户端就是不能生成cookie文件，我真的不知道是为什么了，哪位大哥分析一下是什么原因，小弟感激不尽

没仔细看楼主的代码,你的domain是什么值？ domain应该是xxxx.com的形式，比如网站是www.baidu.com,domain应该是baidu.com。
