Hallo,
I'm trying to use hibernate with Annotations but I really don't get it to work. :(
I started with the
tutorial which worked well, but uses the old hbm.xml-files rather than annotations.
So I used the
Manual to make it use annotations.
I added the required libraries, annotated the class with Entity, changed the hibernate.cfg.xml to uste mapping-class and used AnnotationConfiguration to generate the session-factory.
Starting the programm (which worked before) now results in an error:
Code:
[...]

The rerevant Part from the hibernate.cfg.xml is probably:
Code:
<property name="connection.driver_class">org.hsqldb.jdbcDriver</property>
<property name="connection.url">jdbc:hsqldb:hsql://localhost</property>
<property name="connection.username">sa</property>
<property name="connection.password"></property>
<!-- SQL dialect -->
<property name="dialect">org.hibernate.dialect.HSQLDialect</property>
[...]
<mapping class="events.Event"/>
Any Idea what could be wrong there?
Is it correct to specify the database in the config file?
(What would be a better place otherwise?)
Is there a complete example somewhere? (I really couldn't find one with google.)
Thanks in Advantage.
(References to better documentation are gladly welcome.)
