Hibernate Annotations

[Reema Patel]

Hi All,
I've made a simple "Hello World" app with Hibernate Annotations.
I'm struck at getting a SessionFactory. Ive tried bothe the code fragments.

Approach 1 -

  sessionFactory = new Configuration().configure().buildSessionFactory();
  

Here, I get a runtime error saying:

[java] at hello.HelloWorld.main(Unknown Source)
[java] Caused by: org.hibernate.MappingException: An AnnotationConfiguratio
n instance is required to use <mapping class="hello.Message"/>

Approach 2 -

  // Load settings from hibernate.properties
 
AnnotationConfiguration  cfg = new AnnotationConfiguration();
// ... set other configuration options programmatically
cfg.addAnnotatedClass(hello.Message.class);
sessionFactory = cfg.buildSessionFactory();
  

Here I get compilation error saying that AnnotationConfiguration class not found. Whereas I've included the following packages:
import org.hibernate.*;
import org.hibernate.cfg.*;
import javax.persistence.*;

Any help shall be highly appreciated.

Thanks,
Reema
