Servlet 3.0 Program on Tomcat 7.0

Here, I have developed sample project with version 3 servlet on Tomcat server.

Folder Structure:
Tomcat -- > webapps -- > sample -- > WEB-INF -- > classes

Now just write a servlet class using servlet 3.0 standards like MyServlet.java.

My Servlet.java:

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("/myServlet")

public class MyServlet extends HttpServlet {

      private static final long serialVersionUID = 1L;

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

            // TODO Auto-generated method stub

            PrintWriter out = response.getWriter();

            out.print("Welcome to Servlet World!!!");

      }

}

Optional :Copy the following web.xml file into WEB-INF folder. It is optional as we are not using application level settings.

web.xml    

<xml version="1.0" encoding="UTF-8"?>

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">

</web-app>

Compile the MyServlet.java and copy the class files in classes folder.

Now start the tomcat server with startup.bat located in tomcat/bin folder and wait for startup.

Now enter the following address to see the result of our servlet.

http://localhost:8080/sample/myServlet
