logonform.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.logon;

import javax.servlet.http.HttpServletRequest;
import org.apache.struts.action.ActionError;
import org.apache.struts.action.ActionErrors;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionMapping;
