思路：
1.在struts.xml中配置好默认的语言：
2.在jsp页面中，设置一些链接()，这些链接是Action类，然后通过这些链接，在Action中设置好相应的参数, 并将它保存在application对象中。
3.在跳转后的jsp页面中，通过获取application对象的相应的属性的值，以后在相应的表单中通过设置隐藏属性，这样子在以后的跳转页面都会显示相应的语言了。
4.具体的代码如下：
< xml version="1.0" encoding="UTF-8" >
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags" %>
<%
String lang = (String)application.getAttribute("lang");
if (lang == null)
{
lang = "zh_CN";
}
session.setAttribute("language", lang);
%>
"/>

public class UserBean
{
private String userName;
private String passWord;
public UserBean(){}
public String getUserName() {
return userName;
}
public String getPassWord() {
return passWord;
}
public void setUserName(String userName) {
this.userName = userName;
}
public void setPassWord(String passWord) {
this.passWord = passWord;
}
}
//进行语言的设置：

return SUCCESS;

}
