The origin server did not find a current representation (404 error)

Question

i have a problem. I don't know how to solve. I get an error: Type Status Report Description The origin server did not find a current representation for the target resource or is not willing to disclose that one exists. Apache Tomcat/9.0.78

I use the usual intellij idea (not ultimate). I use only two files in my project(pom.xml,MyServlet ) I tried to use jakarta, didn't help, also changed tomcat 10,9,8 version, didn't help either.It should work without intellij idea ultimate. Idk . In url i use :

http://localhost:8080/hello-servlet

pom.xml

MyServlet

package org.example;

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

@WebServlet( urlPatterns = {"/hello-servlet"})
public class MyServlet extends HttpServlet {

    @Override
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException {
        response.setContentType("text/html");
        PrintWriter writer = response.getWriter();
        try {
            writer.println("<h2>Hello from HelloServlet</h2>");
        } finally {
            writer.close();
        }
    }
