Hello everyone, I have a servlet (TodayServlet) created in eclipse but when I run it on Tomcat server it's leading to a wrong url and it's showing "HTTP Status 404 - Not Found" error. Please how can I resolve this issue? This is the wrong URL that it's leading to -

http://localhost:9999/webdemo/WEB-INF/classes/servlets/TodayServlet.java

but when I changed it to this url -

http://localhost:9999/webdemo/today

it works. Why can't Tomcat pick the right url? I am using Tomacat 10.0.4 version. Thanks for any help.

What I have tried:

package servlets;

import java.io.IOException;
import java.io.PrintWriter;
import java.time.LocalDateTime;

import jakarta.servlet.ServletException;
import jakarta.servlet.annotation.WebServlet;
import jakarta.servlet.http.HttpServlet;
import jakarta.servlet.http.HttpServletRequest;
import jakarta.servlet.http.HttpServletResponse;

@WebServlet("/today")
public class TodayServlet extends HttpServlet {
	private static final long serialVersionUID = 1L;

	protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		String now =  LocalDateTime.now().toString();
		PrintWriter pw =  response.getWriter();
		pw.println("<h1 style='color:blue'>" + now + "</h1>");
	}
}
