struts2 session 解读

httpsession < session　＝　servletactioncontext.getrequest().getsession();
        例：

        public string findall(){
     httpsession session = servletactioncontext.getrequest().getsession();
        list = userservice.find();
     session.setattribute("list", list);
        return this.success;
    }
        在jsp中如何得到session中的属性呢：
        如下：

         s:iterator value="#session.list" id="user"
            s:property value="user.userid"
            s:property value="user.firstname"
            s:property value="user.lastname"
         s:iterator
