Una volta ho avuto questo problema con wildfly 8, ma è stato risolto include eclipselink.jar in $ WILDFLY_HOME/modules/system/layers/base/org/eclipse/persistence/main e l'aggiornamento del module.xml con risorsa radiceDistribuzione fallita su Wildfly 9
<resource-root path="eclipselink.jar" />
e anche per quanto riguarda il mio modulo EJB pom.xml
<dependency>
<groupId>org.eclipse.persistence</groupId>
<artifactId>eclipselink</artifactId>
<version>2.6.0</version>
<scope>provided</scope>
</dependency>
Questo funziona bene in wildfly 8. *. Purtroppo impiegando la stessa tecnica per wildfly 9CR1 ha costantemente fallito il con il ceppo di seguito:

ho anche provato a rimuovere il
<resource-root path="eclipselink.jar" />
eclipselink.jar
ma ottenere un diverso errore di Persistence Provider non trovato. Potrebbe essere un bug Wildfly o c'è qualcosa che non sto facendo bene?
Sembra che tu stia caricando due diverse classi 'javax.persistence.spi.PersistenceProvider'. Eclipse collega questo pacchetto all'interno del suo archivio? –
No, la dose di eclipselink.jar non ha javax.persistence.spi.PersistenceProvider – Paullo
È forse impacchettata nel tuo EAR? Ce ne sono sicuramente due copie sul tuo percorso di classe. –
