public abstract class BaseAction extends DispatchAction {
    public static String USER_IN_SESSION="user_in_session";

    public String getUser(HttpServletRequest request){
    String userName=(String)request.getSession().getAttribute(USER_IN_SESSION);
    return userName;
    }
    public ActionForward execute(ActionMapping mapping, ActionForm form,
            HttpServletRequest request, HttpServletResponse response)
            throws Exception {
           String userName=getUser(request);
           if(userName==null||"".equals(userName)){
            return new ActionForward("login");
           }

           return super.execute(mapping, form, request, response);
    }
    public Session getHibernateSession(HttpServletRequest request){
    return (Session)request.getAttribute(OpenHibernateSessionInView.HIBERNATE_SESSIN_KEY);
    }
}
