I am receiving a 404 error (in the web browser console) upon sending a GET request from an html page via jquery to my java servlet .class file.
I honestly don't know what I should be doing after creating the core files in my IntelliJ maven-webapp project:
pom.xml, MyTestServlet.class, web.xml, index.html, do.js
I am building my project to a folder called "target" via:
Build > Build Artifacts >> All Artifacts > Build
And then, I take all the files in target and upload them to my department's server, but when I navigate to index.html and click the button, it returns a 404 error on the GET request instead of printing out the text specified in the servlet.
Here is the file structure of the project:
Here is the file structure of the result:
"MyTestServlet.java" File (the Java Servlet):

//@WebServlet("/MyTestServlet") <-- idk what i'm doing
public class MyTestServlet extends HttpServlet {

this.doGet(request,response);
}
@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String text = "some text boiii";
response.setContentType("text/plain"); // Set content type of the response so that jQuery knows what it can expect.
response.setCharacterEncoding("UTF-8"); // You want world domination, huh?
response.getWriter().write(text); // Write response body.
}

Can someone guide me as to what I should change to make this work, I feel I am quite close to a solution here? Also let me know if there are better ways about going about this problem, I have briefly heard of web servlet 3.0 but could not find any good resources on it for IntellliJ and Maven. Thanks!
