Я создал простую библиотеку пользовательских тегов. Но когда я запускаю JSP, я получил ошибку ниже кода. Может кто-нибудь объяснить мне ошибку.

Мой класс Java
public class Test extends SimpleTagSupport{
@Override

System.out.println("tag work");
}
}
Обновлен вопрос
Я переместил класс Java в папку. но все равно получил ошибку при компиляции.
