HelloWorld servlet

pytanie zadane 13 lipca 2016 w Java przez Aisekai Nałogowiec (42,190 p.)

Cześć. Ucząc się javy ee, napotkałem na problem (Eclipse Neon + Tomcat 7.0) "The requested resource is not available". Jak go rozwiązać? :

package pl.helloWorldServlet.servlets;

import java.io.*;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;


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

    
    public HelloWorld() {
    	
    }

	
	protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		response.getWriter().append("Served at: ").append(request.getContextPath());
		PrintWriter out = response.getWriter();
		
		out.println("<html><body> Hello World! </body></html>");
		
	}

	
	protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		
		doGet(request, response);
	}

}
