You should use Ejb3Configuration instead of the normal configuration. Refer to the entity manager documentation, at the end of the bootstrapping section in the hibernate documentation.

(copied from above source with minor adaptations)

Ejb3Configuration cfg = new Ejb3Configuration();
EntityManagerFactory emf = 
  cfg.addProperties(properties)                  // add some properties
     .setInterceptor(myInterceptorImpl)          // set an interceptor
     .addAnnotatedClass(MyAnnotatedClass.class)  // add a class to be mapped
     .addClass(NonAnnotatedClass.class)          // add an hbm.xml file using the Hibernate convention
     .addResource("mypath/MyOtherCLass.hbm.xml") // add an hbm.xml file
     .addResource("mypath/orm.xml" )             // add an EJB3 deployment descriptor
     .configure("/mypath/hibernate.cfg.xml")     // add a regular hibernate.cfg.xml
     .buildEntityManagerFactory();               // create the entity manager factory

As you can see, you can mix a lot of different types of configuration.

If it's only for the schema update part, you can just set a property in your persistence.xml: hibernate.hbm2ddl.auto:

   org.hibernate.ejb.HibernatePersistence
   
     …
