/**
 * 标题： 登陆界面层
 * 小组：SEX
 * 时间：2007.8.31
 * 版本：1.0
 * 类名：SLoginMenu
 * 提示各组件命名规则以-后为前缀：JPanel--pnl,JScrollPane--scp,JTextArea--txa,JTextFileld--txt,JLabel--lbl,
 *                            JButton--btn,JCheckBox--chk,JComBox--cbo
 * 本类主要实现：通过连接数据库，核对输入用户帐号，密码。
 * 细节：界面层需导入javax.swing.*;包
 * 1：判断用户帐号，密码框是否为空，并重新获得焦点------文本框名：userName
 * 2：如果输入帐号既密码正确，给出提示（要求弹出消息框）-----密码框：userPwd
 * 3：判断登陆人员的等级情况（即属于哪一部门） ----下来菜单：cbodept
 * 4：以上判断都只需调用事务层SLonginAction类的处理方法boolean isLogin(String name,String pwd)
