java se with hibernate and JavaDB. How do i deploy application?

Question

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">
<hibernate-configuration>
  <session-factory>
    <property name="hibernate.dialect">org.hibernate.dialect.DerbyDialect</property>
    <property name="hibernate.connection.driver_class">org.apache.derby.jdbc.ClientDriver</property>
    <property name="hibernate.connection.url">jdbc:derby://localhost:1527/sample</property>
    <property name="hibernate.connection.username">app</property>
    <property name="hibernate.connection.password">app</property>
    <property name="hibernate.show_sql">true</property>
    <property name="hibernate.query.factory_class">org.hibernate.hql.classic.ClassicQueryTranslatorFactory</property>
    <mapping resource="entity/PurchaseOrder.hbm.xml"/>
    <mapping resource="entity/Customer.hbm.xml"/>
    <mapping resource="entity/ProductCode.hbm.xml"/>
    <mapping resource="entity/Product.hbm.xml"/>
    <mapping resource="entity/MicroMarket.hbm.xml"/>
    <mapping resource="entity/Manufacturer.hbm.xml"/>
    <mapping resource="entity/DiscountCode.hbm.xml"/>
  </session-factory>
</hibernate-configuration>

Yes you can using hbm2ddl property, See this

It isn't good thing to handle such things by our app, instead make your app to accept different configurations using properties file may be

thank you for answer and link. But i reaaly need our app to check if db started, and if not start it

may be you can invoke native commands from java but its bad because many time it needs some password to start the DB and it can be different per machine.. so better to write it in setup guide :)

In my app when Hibernate makes first queries it takes the most time. I could use jdbc connection once at startup. can i tell hibernate to use establised connection?
