下面是我的代码　请各位高手看看吧　　帮帮忙　小弟新到公司　在线等　谢谢！！！　
public ActionForward register(ActionMapping mapping, ActionForm form,
                                  HttpServletRequest request,
                                  HttpServletResponse response) throws
        Exception {
       
TbAuthManager mgr = (TbAuthManager) getBean("tbAuthManager"); TbAuthForm tbauthForm = (TbAuthForm) form;
TbAuth tbauth = new TbAuth();
copyProperties(tbauth, tbauthForm);
        String year = request.getParameter("year");
        String mon = request.getParameter("mon");
        String day = request.getParameter("day");
        String bd = year+"-"+mon+"-"+day;
        GetDate currentdate = new GetDate();
        Date birthday = currentdate.getStringToDate(bd);
       
        String prov = request.getParameter("select");
        String city = request.getParameter("select2");
        String street = request.getParameter("myaddress");
        String myaddress = prov+city+street;
       
        TbLoginlog tbloginlog =(TbLoginlog)request.getSession().getAttribute("tbloginlog");
       
            
        tbauth.setId(currentdate.getID());
        tbauth.setUserid(tbloginlog.getUserid());
        tbauth.setBirthday(birthday);
        tbauth.setMyaddress(myaddress);
        mgr.saveTbAuth(tbauth);        
      
        TbUserManager usermgr = (TbUserManager) getBean("tbUserRegistManager");
        System.out.println(tbloginlog.getId());
        TbUser tbuser = (TbUser) usermgr.getTbUserid(tbloginlog.getUserid());
        tbuser.setAuthstate("y");
        
        usermgr.saveTbUser(tbuser);
        return mapping.findForward("update");
}
    }
我在前台想取TbAuth中的值，在这个action中都能输出，但是到前台就取不出来　bean中的get set方法都有
