3. Hello avec un Servlet

import java.io.*;

import javax.servlet.*;

import javax.servlet.http.*;

public class HelloServlet extends HttpServlet {

    // Handle the Get Method

protected void doGet(HttpServletRequest request, HttpServletResponse response)

	throws ServletException, IOException {

		PrintWriter out ;

		// Content type and other HTTP response header fields

		response.setContentType("text/html");

		// get a print writer, to write out the data of the response

		out = response.getWriter();

		// Write ...

		String header = "<HTML><HEAD><TITLE>Hello Client!</TITLE></HEAD>";

		out.println(header + "<body>");

		out.println("<h1>Hello Client!</h1> How is life at Tecfa ?");

		out.println("</BODY></HTML>");

		out.close();

    public String getServletInfo() {

	return "HelloClientServlet by DKS";

Java:          import java.io.*;

Duservlet kit: import javax.servlet.*;

               import javax.servlet.http.*;

public class HelloServlet extends HttpServlet { ... }

protected void doGet
(HttpServletRequest request,HttpServletResponse response)

		throws ServletException, IOException { .... }

Le servlet passe deux variables à cette méthode:

	response.setContentType("text/html");

	out = response.getWriter();

	out.println( ....)

out.close()
