how to get a Configuration without configfile?

Hibernate version: 3.2.0.ga

Mapping documents: by annotations

Name and version of the database you are using: MySQL 5.0.27

Hello,

I have to use an openSessionInView-pattern (cause of freemarker and lazy loading).

My problem is how to get a org.hibernate.cfg.Configuration without using the hibernate.cfg.xml OR how I have to configure this file cause all my mappings are done by annotations inside the @Entity-classes and my datasources are defined in a *-ds.xml-file.

Thanks - Bastian

Code:

sessionFactory = new AnnotationConfiguration()
   .addPackage("test.animals") //the fully qualified package name
   .addAnnotatedClass(Flight.class)
   .addAnnotatedClass(Sky.class)
   .addAnnotatedClass(Person.class)
   .addAnnotatedClass(Dog.class)
   .addResource("test/animals/orm.xml")
   .buildSessionFactory();

Thanks for the reply.
But my question was how to get a Configuration without considering the Entity classes.

If I use addAnnotatedClass(...) I destroy the single-point-of-truth. It is not useable to add all entities manually.

Is it possible that the configuration looks itself for all annotated classes?

sessionFactory = new AnnotationConfiguration().buildSessionFactory(); does not work.

Code:

org.hibernate.HibernateException: Hibernate Dialect must be explicitly set
....

I want to get the datasource from the *-ds.xml file.

1. If your persistence.xml is in META-INF of the package that you're deploying from (the one containing your entities), it will pick up all annotated classes. Just don't set the "exclude-unlisted-classes" option. I would recommend creating a JAR with the entities and persistence.xml as a unit....

2. Dialect is not DataSource. You must tell Hibernate which Dialect to use in your database.
