I have a problem. I am new in hibernate and I want to write a very simple example with HibernateOGM. I get an Exception that says:
Caused by: org.hibernate.HibernateException: Unable to instantiate specified TransactionFactory class [org.transaction.JDBCTransactionFactory]I have searched really alot, but I couldn't find any solution for my problem. As I understand, the problem occures in this line:
Code:
sessionfactory=cfgogm.buildSessionFactory(serviceregistry);
If I comment the other lines I have no exception, only INFOS.
this is my Stacktrace:
Code:
at org.hibernate.engine.transaction.internal.TransactionFactoryInitiator.initiateService(TransactionFactoryInitiator.java:80)
at org.hibernate.ogm.transaction.impl.OgmTransactionFactoryInitiator.buildServiceInstance(OgmTransactionFactoryInitiator.java:61)
at org.hibernate.ogm.transaction.impl.OgmTransactionFactoryInitiator.buildServiceInstance(OgmTransactionFactoryInitiator.java:41)
at org.hibernate.ogm.service.impl.OptionalServiceInitiator.initiateService(OptionalServiceInitiator.java:37)
at org.hibernate.service.internal.StandardServiceRegistryImpl.initiateService(StandardServiceRegistryImpl.java:69)
at org.hibernate.service.internal.AbstractServiceRegistryImpl.createService(AbstractServiceRegistryImpl.java:176)
here you can find my code and hibernate.cfg.xml and pom.xml:
Code:
OgmConfiguration cfgogm=new OgmConfiguration();
cfgogm.configure("hibernate.cfg.xml");
serviceregistry=new ServiceRegistryBuilder().applySettings(cfgogm.getProperties()).buildServiceRegistry();
sessionfactory=cfgogm.buildSessionFactory(serviceregistry)
hibernate.cfg.xml is:
Code:
<?xml version="1.0" encoding="UTF-8"?>
