String type = request.getParameter("type");//执行类型

int diId = pgroups.getPgId();//取得Bean的一个编号
List subGroups = DAO_Groups.doSelectGroups(" and Cg_Parent=" + diId);//根据Id查找

一个JSP文件：
[code="html"]
<%@ page contentType="text/html; charset=GB2312" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>

[/code]
请教各位大侠~！在JSP中怎么取得在action中动态设置的request作用域变量~！急啊~！
