Witam, mam pewien kod który powinien działać jako servlet projektu Apache FOP do konwertowania XML+XSL:fo do postaci PDF, sam od siebie stworzyłem Applet który działa, nawet na serwerze, jednakże problem w nim jest dość specyficzny, tzn. trzeba potwierdzać użycie każdej biblioteki co przy 13 daje ładną liczbę klikania OK...

Dołączyłem do Eclipse wszelkie potrzebne biblioteki, plik nie pokazuje żadnych błędów, po odpaleniu pliku CreatePDF.java, dostaje komunikat "The selection cannot be launched, and there are no recent launches" Oczywiście sprawdziłem co to za błąd, wchodzę do Run Configurations, wybieram Java Application, no i tu jest pies pogrzebany co wybrać jako main class aby to działało ?

Poniżej przesyłam kod źródłowy:
