Hibernate ogm Neo4j объект управления ошибкой

Question

Я пытаюсь подключиться к базе данных Neo4j. Моя база данных загружена с сайта Neo4j "Cineacts Actors &Movies". Он расположен на C:\NewMovies

вот мое приложение:

public class App 
{
    private static final String JBOSS_TM_CLASS_NAME = "com.arjuna.ats.jta.TransactionManager";
    public static void main( String[] args )
    {  
TransactionManager tm = getTransactionManager();
        //build the EntityManagerFactory as you would build in in Hibernate Core
      EntityManagerFactory emf = Persistence.createEntityManagerFactory("ogm-jpa-tutorial");
System.out.println( "Hello World!" );
    }

   public static TransactionManager getTransactionManager() {
        try {
            Class<?> tmClass = App.class.getClassLoader().loadClass( JBOSS_TM_CLASS_NAME );
            return (TransactionManager) tmClass.getMethod( "transactionManager" ).invoke( null );
        } catch ( ClassNotFoundException e ) {
            e.printStackTrace();
        } catch ( InvocationTargetException e ) {
            e.printStackTrace();
        } catch ( NoSuchMethodException e ) {
            e.printStackTrace();
        } catch ( IllegalAccessException e ) {
            e.printStackTrace();
        }
        return null;
    }
}

мой файл постоянства:

пожалуйста, есть идеи?

Answer 1

Удалить

   <property name="hibernate.transaction.jta.platform"
                  value="org.hibernate.service.jta.platform.internal.JBossStandAloneJtaPlatform"/>

из файла persistence.xml. HibernateOGM для neo4j в настоящее время использует обходное решение для транзакций внутри самого OGM.

Это теперь отражено в последнем бета-руководстве. Посмотрите на окно предупреждения
