I have run into this problem in previous applications -- so I just created a hibernate.properties file and it would work. But my understanding is that this properties file is going away. For some reason my hibernate.cfg.xml is never picked up when I put it in the src directory -- it is first in my classpath when I run the HelloWorld example.

Could this have anything to do with me being on a mac running OS X?

Here is my hibernate.cfg.xml file:

<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">



<hibernate-configuration>
<session-factory>
<property name="hibernate.connection.username">sa</property>
<property name="hibernate.dialect">org.hibernate.dialect.HSQLDialect</property>
<property name="hibernate.connection.url">jdbc:hsqldb:hello</property>
<property name="hibernate.connection.driver_class">org.hsqldb.jdbcDriver</property>
<property name="show_sql">true</property>
<property name="hbm2ddl.auto">create</property>

<mapping resource="hello/Message.hbm.xml"/>
</session-factory>

</hibernate-configuration>

Any help is greatly appreciated -- I have training tomorrow and I was walking through the CBT and I hit this config issue again.

Thanks.

Do you use the HibernateUtil class and is your startup call "new Configuration().configure().buildSessionFactory()"?

Hi there:-)

No not on the CBT am I using the HibernateUtil class -- although I am familiar with it from other projects.

Yes my code is as such:

sessionFactory = new Configuration().buildSessionFactory();

It is exactly as you outlined in your CBT :-)

Thank you for any help.

Thank you Sir! ...
I as can be seen above ... I did not call configure().

This api call slipped by me ... it states it right in the javadoc ... sorry and thank you for your time.
