Я использую Netbeans версии 8.2 для отработки моего весеннего MVC проекта. Версия IDK по умолчанию, предоставляемая netbeans, составляет 1,8, я использую этот проект для изучения проверки формы. Я использую все библиотеки, необходимые для этого проекта, включая старую версию, сервер, который я использую здесь, GlassFi sh 4.1.1.

мои ошибки здесь:
