title: JPA/JSP/EJB : How to create tables from entities?
body: <p>I'm learning how to use JPA with NetBeans/Glassfish.</p>
  
  <p>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.</p>
  
  <p>But when I look in services to my database, I don't see any table corresponding to the entities. What should I do now?</p>

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