Then the authentication with LoginAction works or not. But I would like to write red error when the authentication fails. ... public void validate() { if (userName.length() != 0 && password.length() != 0 && !(AuthenticateUser(userName, password))) { addFieldError("userName", " The Identification has failed"); } } When the Authenticate fails, the message works with "The Identification has failed" , but the color is not red in the loginForm.jsp...
