Jestem na etapie nauki Springa. Uczę się z książki "Spring mvc przewodnik dla początkujących" i przerabiając przykład z uzywania znaczników Spring Security natknąłem się na problem i nie mam kompletnie pojęcia co robie nie tak. Zarówno w login.jsp jak i addProducts.jsp wykrywa mi błąd podczas użycia mapowania "/j_spring_security_check", a w momenie gdy próbuje się zalogować wyrzuca mi "HTTP Status 404 – Not Found". Byłby w stanie mi ktoś powiedzieć co jest przyczyną błędu? Przejrzałem wiele podobnych problemów, ale nie byłem w stanie zrozumieć jak zastosować poszczególne wskazówki umnie :x
