Why Isn't Hibernate Automatically Creating My Database Tables?

Automatically Creating/Updating Database Tables with Hibernate

Your code example includes a persistence.xml configuration with the property hibernate.hbm2ddl.auto set to create. As the documentation indicates, this should automatically create the tables based on your entity classes.

However, if the table is not being created, confirm that:

• "hibernate" is included in property names: Ensure the properties are referenced as hibernate.hbm2ddl.auto (not hbm2ddl.auto).
• Entity annotation is included: Verify that your @Entity annotation is present on your ServerNode class.
• element is defined in persistence.xml: Check if your persistence.xml includes the proper element to specify the persistent class.
• Table annotation is present (optional): As suggested in the answer, explicitly specify the table annotation (@Table) on your entity class, even though Hibernate can typically infer the table name based on the class name.

If all of these are in order, you may need to investigate further into the underlying database connection, JDBC driver, or any potential exceptions that may be occurring. It is recommended to enable debug logging to see what Hibernate is doing behind the scenes.
