Applicazione netbeans platform application

[tritrillidan]

Salve, sto seguendo un tutorial su netbeans per creare applicazioni CRUD.
(il tutorial è il seguente:tutorial )

Sono riuscito a seguirlo fino alla fase della creazione del window component e al testing dello stesso, riesco a compilare senza errori ma al momento del testing dell'applicazione realizzata fin ora si genera il seguente errore:

Caused: javax.persistence.PersistenceException: No Persistence provider for EntityManager named programmaLibraryPU
        at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:84)
        at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:54)
        at org.UI.lavoriTopComponent.<init>(lavoriTopComponent.java:35)
        at org.UI.lavoriTopComponent.getDefault(lavoriTopComponent.java:89)

le righe del codice realizzato che danno l'errore sono:
35

EntityManager entityManager = Persistence.createEntityManagerFactory("programmaLibraryPU").createEntityManager();

89(riga in grassetto sottolineata)

 public static synchronized lavoriTopComponent getDefault() {
         if (instance == null) {
          instance = new lavoriTopComponent();  
           }
         return instance;
     }

qualcuno mi sà dire a cosa potrebbe essere dovuto questo problema?
su cosa dovrei agire per cercare di risolverlo?

[satifal]

Hai creato il file "persistemce.xml" come indicato nel paragrafo "Integrating the Database"?

[tritrillidan]

si il file persistenze.xml è stato creato in automatico quando ho creato la class library

[LeleFT]

Posta il contenuto del file "persistence.xml" e dicci anche quale provider di persistenza intendi usare (forse Hibernate?).


Ciao.

PERSISTENCE.XML

provider di persistenza: eclipselink JPA2.0

[LeleFT]

Alcune domande:

1) Sicuramente il trace dell'eccezione è più lungo rispetto a quello che hai postato. Puoi portare il trace completo dell'eccezione?

2) Come fai ad effettuare il testing dell'applicazione?

Nel frattempo dò una sistemata all'indentazione del file XML da te postato, giusto per avere un'idea chiara del suo contenuto.


Ciao.

il testingvorrei farlo avviando il programma ma non riesco a farlo perchè avviandolo si generano questi problemi

[LeleFT]

Non sembra che tu abbia postato tutto il trace dell'eccezione (dovrebbe esserci qualcos'altro prima), ma da quello che vedo sembrerebbe che non riesca a leggere il file XML con le configurazioni di persistenza.

Prova ad avviare l'applicazione al di fuori di NetBeans, andando nella directory "dist" del progetto e copiando tutto il suo contenuto da qualche altra parte e provando ad avviare il JAR.


Ciao.
