Мой сервлет не работает вообще.Я получаю HTTPS Status 404 - Not Found.Ниже приведен полный код для того же: -

Я новичок в сервлете, поэтому, возможно, я бы что-то пропустил.Когда я нажимаю на ссылку, у меня появляется ошибка «HTTP Status 404 - Not Found».Я действительно не понимаю, что я сделал не так.
Я использую NetBeans IDE 8.2 и GlassFish 4.1.1
