Servlet 3 – Contoh Hello World

Project Servlet 3 ini membutuhkan Java Enterprise Edition versi 3, Anda perlu menggunakan Application Server atau Web Server yang sudah mendukung Servlet 3, seperti Glassfish 3, JBoss 6 atau Apache Tomcat 7.

package khannedy.web.servlet;

import java.io.IOException;
import java.io.PrintWriter;
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(name = "HelloWorld", urlPatterns = {"/HelloWorld"})
public class HelloWorldServlet extends HttpServlet {

    private static final long serialVersionUID = 1L;

    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        PrintWriter writer = resp.getWriter();
        writer.write("Hello World");
        writer.close();
    }
}
