Mam kod który generuje mi z jednego beana jego zawartość do PDFa.
Teraz chcę wydrukować beana który zawiera inne beany. Znalazłem informację, iż robi się to z wykorzystaniem subreportów. Czyli główny bean to główny raport, a beany zawarte w głównych są drukowane w subreportach.

Szablony tworzę w jasper Studio.

  1. Jak stworzyć subreport do głównego raportu ?

W tym momencie w Jasper Studio dodaję subreport na którym dodaję pole które chcę wydrukować z zagnieżdzonego beana.
W głównym raporcie wskazuję atrybut z encji który przechowuję listę zagnieżdzonych beanów.
<field name="policyHolder" class="java.util.List" />

BŁĄD Z Konsoli to:
net.sf.jasperreports.engine.JRException: Resource not found at : TestPolisaSub.jasper

Wnioskuję, że mam błędnie połączony RAPORT główny z subreportem.

Proszę o pomoc / wskazówki.
