java.io.IOException;
import java.io.PrintWriter;
import
javax.servlet.ServletException;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class HelloServlet extends HttpServlet {
/**
* Constructor of the object.
*/
public HelloServlet() {
super();
}
/**
* Destruction of the servlet. <br>
*/
public void destroy() {
super.destroy(); // Just puts "destroy" string in log
// Put your code here
}
/**

*
* @param request the request send by the client to the server

*/
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
request.setCharacterEncoding("UTF-8");
response.setCharacterEncoding("UTF-8");
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.println("<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.01 Transitional//EN\">");
out.println("<HTML>");
out.println(" <HEAD><TITLE>A Servlet</TITLE></HEAD>");
out.println(" <BODY>");String requestURI=request.getRequestURI();
out.println("<form action='"+requestURI+"' method='post'>");
out.println("Input your name:<input type='text' name='name'/>");
out.println("<input type='submit'/>");
out.println("</form>");
out.println("");
String name=request.getParameter("name");
if(name!=null && name.trim().length()>0){
out.println("Hello,<b>"+name+"</b>.");
out.println(" </BODY>");
