listuseraction.java

本人课程设计时做的一个用struts框架实现的基于cmmi2的项目管理系统的原型。还有部分功能尚未实现

package com.cmmi2pms.sa.user;

import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpSession;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
