Answer 1

You need to add the following property to your configuration:

Drop and Recreate everytime SessionFactory is created and destroyed:

<property name="hbm2ddl.auto">create-drop</property>

Other possible options:

• validate: validate the schema, makes no changes to the database.
• update: update the schema.
• create: creates the schema, destroying previous data.

Answer 2

for future googlers : it was so simple after all , i just needed to build session factory so i added this line and it worked like charm :

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

note that buildSessionFactory() is deprecated in hibernate 4 but i guess you can use the code here to do the same.
