The following exception is ocorring for me:
java.lang.NullPointerException
at com.google.inject.persist.jpa.JpaPersistService.begin(
JpaPersistService.java:77)
at com.google.inject.persist.jpa.JpaLocalTxnInterceptor.invoke(
JpaLocalTxnInterceptor.java:53)
Follows my persistence.xml:
<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd";
version="1.0">
<!-- A JPA Persistence Unit -->
<persistence-unit name="persistence.unit"
transaction-type="RESOURCE_LOCAL">
<provider>org.hibernate.jpa.HibernatePersistenceProvider</
provider>
<!-- JPA entities must be registered here -->
<!--<class>com.wideplay.warp.jpa.JpaTestEntity</class> -->
</persistence-unit>
</persistence>
follows the configuration code:
persistModule = new JpaPersistModule(PERSISTENCE_UNIT_NAME);
install(persistModule);
bind(org.hibernate.Session.class).toProvider(new SessionProvider());
filter("/*").through(PersistFilter.class);
can anyone point me what I'm doing wrong?
regards
Diogo
