No tak jsem pokročil o kus dál. Přidal jsem modul Toplink-essentials z
Libraries a ne jako "Library Wrapper Module Project". Proto nemohl najít
persistence.xml a rozpoznat persistence unit.
Teď mám pro změnu další chybu, kdy už našel persistence.xml, ale asi ho
nemůže parsovat. pak dále:

Ahoj,
nemáte někdo prosím zkušenost s vytvářením modulu pro platformu
netbeans, tak aby modul podporoval java persistence např. Toplink.?
Nemohu najít žádný tutoriál pro NB5.5 či NB6 :(
Pro použití persistence v aplikaci J2SE jsem něco našel a to bez
problémů funguje, na všechno jsou v aplikaci přístupní průvodci, ale
při vývoji modulu NB6 průvodci nejsou přístupní ani nic z
"persistence" (entity class, persistence unit...). Okopíroval jsem do
vytvořeného modulu META-INF a persistence.xml z J2SE aplikace, přidal
knihovnu toplink, javaee.jar.
u každé anotace @Entity v entitních třídách je chybové hlášení že
tento projekt neobsahuje persistence unit, v NB6 je sice hezký
průvodce, který se snaží fixnout tu chybu vytvoření nové persistence
unit, ale po stisku ok se nic neděje. Při stejném pokusu v J2SE
aplikaci se persistence unit normálně vytvoří, ale NB6 modulu ne.
Při pokusu vytvořit:
private static EntityManagerFactory emf =
Persistence.createEntityManagerFactory("persistenceunit");
dojde k exception. Asi evidentně v nastavení projektu není vše v
pořádku a nemůže najít persistence unit:(
