Кроме того, в системе реализована рассылка оповещений. При добавлении задания определенному пользователю, он получает оповещение об этом на почту.

Созданное приложение легко в освоении, удобно в использовании и оперативном получении информации.

Прототип системы документооборота, организованный по модульной архитектуре, может быть легко доработан до коммерческого предложения.

Данная работа помимо этого подразумевала учебную цель: ознакомление с Java Server-Side - технологиями. При разработке системы были использованы современные информационные технологии: JavaEE - JSP, Servlets, JSP, JDBC; технология AJAX. Цель была достигнута.

Система электронного документооборота HotDoc может иметь свое практическое применение, как в средних, так и в крупных организациях, где требуется ведение большого объема документов.
