I have a problem with persisting simple objects to a MS SQL Server. My code works just fine when I am running it with MySQL. But the customer demands MsSQL.
I get no Errors when running it with MS SQL and the output is the same as when running with MySQL. It just doesn´t save it to the DB. Also, the db-table gets locked. It is not possible to access the table with an external application such as MS Query Analyzer.
Someone who have a clue.. here is the details:
Hibernate version: 3 
Mapping documents:
Code:
<hibernate-mapping>
  <class name="com.icr3.model.Test">
    <id name="id" type="long" column="id">
      <generator class="native"/>
    </id>
    <property name="test"/>
  </class>
</hibernate-mapping>
Code between sessionFactory.openSession() and session.close():Code:
public class TestManager extends AbstractManager {
    public void createTest() {
        Test t = new Test();
        t.setTest("hej och hallå");
        try {
            testDao.createTest(t);
        } finally {
            closeSession();
        }
    }
}
Code:
public class TestDAO extends AbstractDAO {
    public void createTest(Test test) {
        try {
            session().save(test);
        }
        catch (HibernateException e) {
            throw new RuntimeException(e);
        }
    }
}
Code:
public abstract class AbstractDAO {
  Logger log = Logger.getLogger(getClass().getName());
  /**
   * The simplest possible way to access the active hibernate session
   * of the current thread.
   */
  protected Session session() {
      return HibernateUtil.currentSession();
  }
}
closeSession() is implemented in AbstractManager and is making a call to :  
HibernateUtil.closeSession()
Code:
public static void closeSession() {
        Session s = (Session) session.get();
        log.debug("SESSION = " + s);
        session.set(null);
        if (s != null) {
            try {
                s.flush();
                s.close();
            }
            catch (HibernateException e) {
                throw new RuntimeException(e);
            }
        }
    }
where testDao is declared in AbstractManager..
