Java 如何在Struts 1.x中检查Ajax弹出JSP页面的验证

我在验证Struts 1.x时遇到了一些问题。我正在打开一个关于Ajax调用的JSP页面。在这个JSP页面（打开的弹出窗口）中，如果我想进行一些验证，比如需要用户标题等，并且在提交表单时，我直接将详细信息提交给所需的action类方法。提交时，我没有使用Ajax提交。我也尝试过Ajax submit，但它对我不起作用。下面的代码是我的action类方法和JSP页面：

Action class
public ActionForward saveNotificationsFormDetails(ActionMapping mapping, ActionForm form,
            HttpServletRequest request, HttpServletResponse response) {
        DynaValidatorActionForm notificationsForm=(DynaValidatorActionForm)form;
        log.info("In saveNotificationsFormDetails method of NotificationsManagementAction");
        String forwardName="failure";
        String filePath = null;
        String webPath = null;
        FileOutputStream outputStream = null;
        ActionMessages messages = new ActionMessages();     
        User user=null;     
        try
        {
            int userId=0;
            HttpSession session=request.getSession(false);
            if(session!=null)
            {
                user=(User)session.getAttribute("user");
                if(user!=null)
                {

                    if(user.isAdmin()==true)
                    {
                        userId=user.getPrimaryKey();
