I have just started to learn servlet technology, and I'm currently trying to create a very basic web application. Just some pages, trying this thing. I can reach the start page /index.html but I get 404 HTTP status code for other part:
Message:The requested resource [/first] is not available
Description: The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.
My web.xml under WEB-INF is this:
<?xml version="1.0" encoding="UTF-8"?><web-app version="4.0" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"></web-app>My FirstServlet.java is this:
package servlet;import javax.servlet.ServletException;import javax.servlet.annotation.WebServlet;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import java.io.IOException;import java.io.PrintWriter;@WebServlet("/first")public class FirstServlet extends HttpServlet { @Override protected void doGet(HttpServletRequest req, HttpServletResponse response) throws ServletException, IOException { response.setContentType("text/html"); PrintWriter pw = response.getWriter(); pw.println("<html>"); pw.println("<body>"); pw.println("Welcome to servlet"); pw.println("</body>"); pw.println("</html>"); pw.close(); }}The context path is /. I tried urlPatterns at WebServlet annotation. I'm trying it under IntelliJ IDEA Community, with Smart Tomcat plugin, with Tomcat 10.1.24 installed, and with Java 11. I ran mvn clean package.
After starting the application I can reach index.html with http://localhost:8080/ but I can't reach http://localhost:8080/first .
I'm trying to find the solution for some time but I wasn't able to do that. I read through the threads here (at least tried), too, but didn't find it. From a Dockerfile image I tried it with Tomcat 9.0.89 but I get the same / 404 http status code.
I would like to ask for your help in this question. If I can provide any useful additional relevant information, please let me know.
Thank you very much for your help in advance.
