method getServletConfig() is undefined for the type TestInitParams

[Omar Perez]

Greetings Community, God Bless

I'm currently on page 154 of the Book HeadFirst Servlets and JSP, using eclipse IDE and the servlet.api from Tomcat's latest release. However I'm getting the following error in eclipse "the method getServletConfig() is undefined for the type TestInitParams". I don't know what I'm not doing correctly, could anyone give me a hand explaining me where is my mistake?

Here is my code for the class

package com.example.web;

import java.io.*;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;

public class TestInitParams {

	public void doGet(HttpServletRequest req, HttpServletResponse resp) 
			throws IOException, ServletException {
		resp.setContentType("text/html");
		
		PrintWriter out = resp.getWriter();
		
		out.println("Test init parameters<br>");
		
		Enumeration e = getServletConfig().getInitiParametersNames();
		while(e.hasMoreElements()){
			out.println("<br> param name =" + e.nextElement() + "<br>");
		}
		out.println("My e-mail is: " + getServletConfig().getInitParameter("mainEmail"));
		out.println("<br>");
		out.println("Admin's email is: "+ getServletConfig().getInitParameter("adminEmail"));
	}


}

And here is the code ffor my DD (web.xml)

		<init-param>

	</servlet-mapping>

You need to extend HttpServlet.
