Hello,

I have found a workaround for this, but I wanted to report my experience.

I am starting out with Hibernate and have spent the past few days building my "hello world" ap.

I finally got SchemaExport working and my configuration set up. My database is all set up, etc.

When I do this, it works:

public static void main(String[] args) {
Configuration cfg = new Configuration();
SessionFactory factory = cfg.configure("primeschedule/hibernate/hibernate.cfg.xml").buildSessionFactory();
for(int i=0;i < 5;i++) {
Session session = factory.openSession();
session.beginTransaction();
Practice p = new Practice();
p.setName("tim-" + Integer.toString);
session.save(p);
session.getTransaction().commit();
session.close();
}
factory.close();
}

but when I do this it does not:

public static void main(String[] args) {
Configuration cfg = new Configuration();
SessionFactory factory = cfg.configure("primeschedule/hibernate/hibernate.cfg.xml").buildSessionFactory();
for(int i=0;i < 5;i++) {
Session session = factory.openSession();
session.beginTransaction();
Practice p = new Practice();
p.setName("tim-" + Integer.toString);
session.save(p);
session.flush();
session.close();
}
factory.close();
}

If I run the second test case in JDB it would actually output junk to the screen and crash! When running test case 2 in the standard java interpreter it outputs the INSERT statement, but the records do not post to the database. Weird.

My workaround is to not use FLUSH but instead use getTransaction().commit(). The book "Hibernate Quickly" suggests using the flush command at the end of the session.

Thanks for your attention,

Tim
