Hello World

====== Servlets and JSP ====== ===== Servlets ===== A simple "HelloWorld" servlet, that also prints the current date.

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


public class HelloWorld extends HttpServlet {


   public void doGet(HttpServletRequest req, HttpServletResponse res)
			throws ServletException, IOException {


	res.setContentType("text/html");
	PrintWriter out = res.getWriter();


	out.println("");
	out.println("Hello World");
	out.println("");
	out.println("Hello World");
	out.println("Today is: " + (new java.util.Date().toString()) );
	out.println("");
   } // doGet

} // HelloWorld

In order to run it, do the following: - Place it in a file, HelloWorld.java - Compile it. - Place the resulting HelloWorld.class file in the "servlets" directory. - Run it by pointing browser to: http://server.address/servlets/HelloWorld ===== JSP ===== The same page as above using JSP looks as shown below:
