struts2 JSP Ajax вызов

1 голос
/ 24 июня 2019

Я пытаюсь сделать простой AJAX-вызов в Struts2 JSP, но постоянно получаю эту ошибку: «Диспетчер Struts не найден».Я проверил другие похожие потоки на stackoverflow, и похоже, что все правильно.Пожалуйста, сообщите.

            alert("Some error occured.");
        }
    });

полное сообщение об ошибке: 

The Struts dispatcher cannot be found.  This is usually caused by using Struts tags without the associated filter. Struts tags are only usable when the request has passed through its servlet filter, which initializes the Struts dispatcher needed for this tag. - [unknown location]
