Servlet getRequestURL :

getRequestURL() method reconstruct the requested client URL. It returns the current URL which containing protocol, server name, port number and server path. It doesn't include query string parameters. It returns URL in StringBuffer in place of String so if required you can add query string parameters.

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

public class GetURLExample extends HttpServlet {
	public void doGet(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {
		response.setContentType("text/html");
		PrintWriter out = response.getWriter();

		out.println("Current URL : " + request.getRequestURL());
		
	}
}

web.xml -

<?xml version="1.0" encoding="UTF-8"?>
