Form Submitted In Servlet

My inputted data is note display in the same page when I click on the submit button. Please help me. Whenever submit button is clicked, the inputted values in the textboxes, checkboxes, etc should be displayed in the same page. Here's my code:

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

public class HW extends HttpServlet{

	public void doGet(HttpServletRequest request,HttpServletResponse response) throws ServletException,IOException
		{
			response.setContentType("text/html");
			PrintWriter pw = response.getWriter();
			pw.println("<html>");
			pw.println("<head><title>Home Page</title></title>");
			pw.println("<body>");
			pw.println("<FORM method= post>");
pw.println("<TABLE BORDER= 1>");
    pw.println("<TR>");
        pw.println("<TD>Personal Information</TD>");
    pw.println("</TR>");
   
    pw.println("<TR>");
        pw.println("<TD>");
            pw.println("<TABLE>");
           
            pw.println("<TR>");
                pw.println("<TD>First Name:</TD>");
                pw.println("<TD><input type= text name= fname/></TD>");
            pw.println("</TR>");
           
            pw.println("<TR>");
                pw.println("<TD>Last Name:</TD>");
                pw.println("<TD><input type= text name= lname/></TD>");
