strust框架页面消息封装

strust.xml

<package name="doorwhite" namespace="/doorwhite" extends="struts-default">

   <action name="doorwhiteAction_*" class="com.commsoft.sys.dooraccess.struts.action.DoorwhiteAction" method="{1}">
    <result name="batchisnull">
    ${page}
    </result>
    <result name="success">
    ${page}
    </result>
   </action>
</package>

java代码（部分）
public String importDownUser(){
HttpServletRequest request = this.getHttpServletRequest();
FileOutputStream fos = null;
FileInputStream fis = null;
if(!custfileFileName.contains(".xls")){
request.setAttribute("mess", "请导入.xls格式文件");
        request.setAttribute("download", "");
        return "batchisnull";

}

jsp页面获取

var mess = "${mess}";
