我正在开发一个 Web 应用程序，并且卡在身份验证代码上，我已经在 Eclipse 上使用休眠完成了连接，现在它是关于身份验证，当我提交身份验证时没有任何反应，请帮助我，我是新手。这是 JSP 文件：

这是登录的servlet：

// creation d'un request dispatcher
RequestDispatcher rd = null;
Session s = HibernateSessionFactory.getSessionFactory().openSession();

rd = request.getServletContext().getRequestDispatcher("/AdminServlet");
}
else{

}
rd.forward(request, response);
}
}
finally {

}
