JPA/JSP/EJB : How to create tables from entities?

I'm learning how to use JPA with NetBeans/Glassfish.

I have created a new EE project, and some entities in the EJB. I also created a new database. While creating the entities I also created a new persistence unit. In Data Source I chosed "New data source", and for the database connection I used the one I've created just before.

But when I look in services to my database, I don't see any table corresponding to the entities. What should I do now?

Thanks for your help. And sorry if the question is obvious but I'm really new to this kind of programming.

JPA (2.1) allows you to create the schema appropriate for your JPA entities in your persistence-unit when the EntityManagerFactory is created. The linked page tells you what persistence properties to specify in your persistence-unit for this to happen automatically. (assuming your JPA implementation is for JPA version 2.1)
