1)When i send my application to my teacher, how do i tell it to create some empty tables and populate it with sample data on FIRST launch of application? I know that i can include sql script with my files or something. Can i instruct hibrenate to create empty tables? I have my entities which i use in my application.

2)When my ide (NetNeans) starts, i go to services and start my db (JavaDB) manually, because if i dont, on application startup hibernate complains that he cant connect. How do i tell hibernate start to start db (its on localhost:1527)?

my hebernate.cfg:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
