У меня есть 2 массива, которые мне нужны для JSP. Я отправил пользовательский ввод из первого тега ввода в сервлет и хочу вернуть массив, значения которого зависят от того, что пользователь ввел, но для тестирования я думал, что отправлю обычную строку и напечатаю ее в консоли, но для по какой-то причине это не работает. Когда я go на вкладке сети в Проверяем элемент , я вижу, что получил от сервлета ответ POST , но в консоли ничего не отображается.
Вот мой JSP:
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html>
<html>
<head>

Вот мой сервлет:
package servlet;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
@WebServlet("/foundCountry")
public class foundCountry extends HttpServlet {
private static final long serialVersionUID = 1L;
public foundCountry() {
super();
}
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
response.setContentType("text/html");
System.out.println(request.getParameter("newVal"));
String newVal = request.getParameter("newVal");
response.getWriter().write(newVal+ " ree");
}
}
