FOP tworzenie aplikacji sieciowej

Witam potrzebuje pewnej pomocy ze stworzeniem aplikacji sieciowej która korzystała by z procesora Apache FOP za pomocą którego możliwa byłaby konwersja plików XML na PDF przy pomocy Formatting Objects.

Apache udostępnia nam kod który można użyć

Jednakże problem w tym że nie mam bladego pojęcia jak się dobrać do niego aby stworzyć na jego podstawie działający produkt.
Byłbym wdzięczny za wszelką pomoc, od razu mówię że niestety z Java jestem zielony.

@Edit:
Po uruchomieniu tego projektu w CMD dostaje błędy typu:

error: package org.apache.fop.apps doesnt exist import org.apache.fop.apps.Fop

Jak sobie z nimi poradzić ?
