struts2 JSP Ajax call

Question

I'm trying to make a simple AJAX call in Struts2 JSP, but I'm keep getting this error: "The Struts dispatcher cannot be found." I've checked other similar threads on stackoverflow and it looks like everything is right. Please advise.

Ajax Call:

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

full error message:

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]

Are you using Struts 2 tags in a JSP without going through an action? — Dave Newton, Jun 25 '19 at 05:06
I'm not sure how to rephrase. Are there JSP pages accessed directly, e.g., the jsp extension is in the URL? — Dave Newton, Jun 25 '19 at 11:28
` at jsp_servlet.__404._jsp__tag0(__404.java:162)` so I'd disagree. You're hitting a 404, serving a 404 page, and looks like serving a `404.jsp` that isn't going through an action. — Dave Newton, Jun 25 '19 at 14:36
as you probably already know, I'm completely new to Struts. I've been using this tutorial to make an AJAX call: https://www.websparrow.org/struts/how-to-send-data-from-jsp-to-struts-action-class-using-jquery-ajax, but I can't make it work. Could you please explain what should I do to fix the issue? — Pawel, Jun 26 '19 at 09:42
What's the request being made in the network console? You're getting a 404. What happens if you try to got that URL from the browser directly? — Dave Newton, Jun 26 '19 at 10:45
when I try to hit that URL directly from browser I got: 500 Internal Server Error — Pawel, Jun 26 '19 at 12:06
So you should investigate: (1) that error, (2) why you get a 404. — Dave Newton, Jun 26 '19 at 13:43
