How to create tables from classes

[handro1104]

I am learning Seam and I am very comfortable generating CRUD applications. But now I want to create an application from scratch starting with the classes. I have not been able to figure out how to create the tables from the classes. I am using JBoss developer Studio.

Your help will be greatly appreciated,

Hibernate creates the tables for you if they don't exist already.

see the hibernate.hbm2ddl.auto setting.

Thank you very much max.anderson, but I don't known how to access or modify the hibernate.hbm2ddl.auto setting. I have tried many things related to hibernate in JBoss Developer Studio. Could you please give more details or links where I can find the information?

Thank you very much. Setting to "create" in persistence.xml works.

Well, now I have problems. The first time I selected New->Generate Seam entities and in the dialog I set "use existing entities" and a table was created from my class. However, after I added a property to my class and repeated the process, nothing changed in the table. Then i dropped the table and tried again, but no table was created.

Please tell me what I am doing wrong.

use drop-create to get it to drop the tables and recreate them again.
