I'm trying to connect to Neo4j database. My database is downloaded from Neo4j site "Cineacts Actors &Movies". It located on C:\NewMovies
here comes my Application:
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;
}
}
my persistence file:
