Hello,
I'm trying to do integrations tests in my app, but I get a
NullPointerException when this line is executed:
private static final EntityManagerFactory instance =
Persistence.createEntityManagerFactory("transactions-optional")
See:
Caused by: java.lang.NullPointerException
at org.datanucleus.jpa.EntityManagerFactoryImpl.initialisePMF
(EntityManagerFactoryImpl.java:452)
at org.datanucleus.jpa.EntityManagerFactoryImpl.<init>
(EntityManagerFactoryImpl.java:355)

org.datanucleus.store.appengine.jpa.DatastoreEntityManagerFactory.<init>

(Persistence.java:33)
at javax.persistence.Persistence$createEntityManagerFactory.call
(Unknown Source)
at org.grails.appengine.AppEngineEntityManagerFactory.<clinit>
(AppEngineEntityManagerFactory.groovy:13)
Has anybody any ideas of why I'm getting NullPointerException in
datanucleos jpa EntityManagerFactoryImpl? Any advice that help me to
find how to solve the problem is very welcome, for example what line
452 of EntityManagerFactoryImpl expects?
Regards,
Felipe Cypriano
