Piszę własny kod, aby samodzielnie indeksować niektóre pliki danych. Wszystko działało. Kiedyś zmodyfikowałemschema.xml plik, teraz mam wewnętrzny błąd serwera, który nie mam pojęcia jak go zinterpretować.

Następnie zaglądam do pliku dziennika catalina, mówiąc, że żaden rdzeń nie został utworzony ...

Zaktualizowany plik dziennika catalina powyżej ... tak, usunąłem dane indeksu, ponieważ myślałem, że zamierzam utworzyć nowy indeks ... i zrobiłem to wcześniej, ale nie widziałem do tej pory tego błędu ... jak to naprawić ? :(

Wielkie dzięki!!! (^ bezokolicznik razy)
